Detailed Description

Functions related to accessing and manipulating Attribute and the Attribute-related data of elements.

Attribute Overview

Available types of attributes are enumerated in the API_AttrTypeID structure. The definition of an attribute is described in the API_Attribute structure, which is in fact a union of all types of attributes. All of the attribute structures begin with a common header structure, named [APIAPI_Attr_Head

• The typeID field identifies the type of the attribute.
• The index field gives the current database index of the given attribute. References to any attribute are done through these indices.
• The guid field gives the global unique ID of the given attribute. You can also refer to any attribute through its guid.
• The flags field describes some attribute type dependent information. Possible values are listed at the same place where the given attribute structure is.
• The name field gives the name of the attribute which appears in the appropriate dialogs.
• The modiTime field tells you when the attribute was last modified.

Many attribute related functions use the API_Attribute structure on the parameter list. As a general rule, you have to fill the required fields in the union, then Archicad parses the request based on the values and passes the return parameters in the same parameter. This is why most of the functions do not have the const directive in the prototypes.

---

Retrieving an attribute

Let's see a simple example. Assume you are interested in the definition of the second line type of the data structure. In this case you should use a variable with the type API_Attribute structure.

API_Attribute    attrib = {};
GSErrCode        err;
 
attrib.header.typeID = API_LinetypeID;
attrib.header.index  = 2;
 
err = ACAPI_Attribute_Get (&attrib);

The description of the attribute is returned in the attrib.linetype part of the union. With this function call, you get the basic data of the given attribute, such as the name, the flags, the defined scale, etc., but you do not get the definition of the actual shape of the line type. Since producing this data may be a relatively a long conversion process, this information can be obtained with an additional function call.

API_AttributeDef    defs;
err = ACAPI_Attribute_GetDef (API_LinetypeID, 2, &defs);

In this case, you have all of the additional data related to the particular attribute. The API_AttributeDef structure is a collection of several handles (dynamic memory). If any of them are allocated it contains data. If you do not need the data any more, you have to free the allocated memory blocks to avoid memory leaks. The suggested way is the following:

ACAPI_DisposeAttrDefsHdls (&defs);

If you use this function, it is ensured that all of the dynamic data will be freed, and also that there will be no compatibility problems if your add-on is installed to a newer version of Archicad.

It is very important to examine the error codes returned by the API functions, and parse the returned value.

A typical situation is when you want to go through the instances of a particular attribute type in the database. The following example gives a good template to do that.

API_Attribute  attrib = {};
short      nLin, i;
GSErrCode  err;
 
attrib.header.typeID = API_LinetypeID;
err = ACAPI_Attribute_GetNum (API_LinetypeID, &nLin);
for (i = 1; i <= nLin && err == NoError; i++) {
    attrib.header.index = i;
    err = ACAPI_Attribute_Get (&attrib);
    if (err == NoError) {
        /* do what you want */
    }
    if (err == APIERR_DELETED)
        err = NoError;
}

First you need to get the number of line types in the database. You can do that with the ACAPI_Attribute_GetNum function, but be careful. This function returns the largest index used in the database, not the number of installed attributes, because instances may be deleted. Deleted attributes are not purged from the database immediately, which means that the valid index range is not (always) continuous. This is why the APIERR_DELETED return code has to be handled.

---

Creating an attribute

The attribute creation process is also fairly simple. All you have to do is to fill the appropriate part of the API_Attribute, and optionally the API_AttributeDefExt structure. The ACAPI_Attribute_CreateExt function does the following:

• It checks the data for possible inconsistency. If some problem is encountered it may be corrected automatically or an error code is generated.
• It ignores for example, the index field in the header structure, you cannot influence which index the attribute should be referenced by. This value is automatically generated and returned to you.
• If an attribute exists with the same name in the database, the existing index will be returned. The matching procedure ignores the differences of the attribute definition. Multiple attributes with the same name are not allowed.
• The generated attribute is placed in the data structure and it can be referenced in any subsequent API call.

It is very important that Archicad does not free any dynamic data structure you have allocated and passed to Archicad. They must be freed by your code.

Another important note is the following. Every data structure filled by you must be initialized to zero, for forward compatibility. Fillers may become real data fields in the later versions of the API, so if they are not initialized to zero, the result may be unpredictable.

The template to create an attribute is the following:

API_Attribute          attrib = {};
API_AttributeDefsExt   defs = {};
short               ltypeIndex;
GSErrCode           err;
 
attrib.header.typeID = API_LinetypeID;
/* fill attrib.linetype */
/* fill defs for dashed and symbol line types */
 
err = ACAPI_Attribute_CreateExt (&attrib, &defs);
ltypeIndex = attrib.header.index;
 
ACAPI_DisposeAttrDefsHdlsExt (&defs);

APIERR_BADID

invalid reference;
the attribute type is invalid or the operation cannot apply that type

APIERR_BADINDEX

invalid reference;
the supplied attribute index is out of range

APIERR_DELETED

invalid reference;
the attribute does not exist in the database (deleted)

APIERR_NOTMINE

permission denied;
the attribute is out of the users workspace

Notes

There are certain rules which effect the attribute operations; i.e. they may be refused for some reason. The most important rules are:

• certain attribute types have a fixed number of instances (e.g. pens),
• certain attribute types must have at least one instance (e.g. line types),
• any type of modification is allowed only in the case when the target attribute instance is in the user's workspace

This function is used to create an attribute, defined by the typeID field of the attribute header. The reference index of the newly created attribute is returned in the index field of the attribute header. You cannot create pen and font attributes. The function also checks the data for possible inconsistency. If a problem is encountered it may be corrected automatically, or an error code is generated. If an attribute with the same name exists in the database, the existing index will be returned. The matching procedure ignores the differences of the attribute definition. Multiple attributes with the same name are not allowed. When creating the attribute, the applicable fields should be filled.

ACAPI_Attribute_CreateFolder()

GSErrCode ACAPI_Attribute_CreateFolder

(

API_AttributeFolder &

folder

)

Creates attribute folders. To create a folder, its full path has to be provided. The command will create all folders along the path, if they do not exist.

Since

Archicad 26

Parameters

folder

[in out] Type and path of the attribute folder to create.

Returns

• NoError - The function has completed with success.
• APIERR_BADID - Incorrect folder.typeID was specified, or folder.path is illegal, see remarks.
• APIERR_NOPLAN - There is no open project.
• APIERR_NOACCESSRIGHT - User has no permission to create folders under typeID.
• APIERR_BADPARS - Folder creation is not available for folder.typeID.

Remarks

older.path has to be legal, i.e. all names in the array must not be empty, and must not begin or end with whitespace. If a folder in folder.path already exists, it is not renamed or recreated. Name collision of folders is case insensitive. Examples:

• If the folders A/B exist, and folder.path = a/b/c/d, two new folders, c/d under A/B are created. A and B are not renamed to a and b.
• If the folders A/B/C exist, and folder.path = a/b/c, this has no effect. NoError will be returned. If a folder at folder.path was successfully created, it's unique identifier is set to folder.guid. It can be used later, even if the folder was moved or renamed since it's creation.

Example

    API_AttributeFolder folder {};
    folder.typeID = API_CompWallID;
    folder.path = { "A", "B", "C1" };
    DBVERIFY (ACAPI_Attribute_CreateFolder (folder) == NoError);

ACAPI_Attribute_Delete()

GSErrCode ACAPI_Attribute_Delete

(

const API_Attr_Head &

attrHead

)

Deletes an attribute.

Since

Archicad 26

Parameters

attrHead

[in] The typeID and index fields in the header identifies the attribute to delete.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - The passed parameter (attrHead) is invalid.
• APIERR_REFUSEDPAR - You tried to delete pens, fonts, a solid or an empty fill, or an attribute with index 1.
• APIERR_NOTMINE - The attribute is out of the users workspace.

Remarks

This function is used to delete an attribute, defined by the typeID and index field of the attribute header. Certain attributes in the database can not be deleted; see the return values. Note, that deleting an attribute do not effect any changes in the element database; they will refer to an attribute which is missing. That is not a problem, the server applications work in the same way when an attribute is deleted from the menus. The only exception is the layer attribute. Once a layer is deleted all the elements will be deleted; no matter in which database they are. The floor plan and all the section/elevations will be scanned to delete the elements which are on the given layer. You can delete more than one attribute of the same type with the ACAPI_Attribute_DeleteMore function. This function is a non-undoable data structure modifier function. See more details on this topic at Command Overview.

Example

API_Attribute attrib = {};
attrib.header.typeID = API_LinetypeID;
attrib.header.index = 5;
 
GSErrCode err = ACAPI_Attribute_Delete (attrib.header);

ACAPI_Attribute_DeleteFolder()

GSErrCode ACAPI_Attribute_DeleteFolder

(

const API_AttributeFolder &

folder

)

Deletes an attribute folder and all the folders and attributes it contains.

Since

Archicad 26

Parameters

folder

[in] The folder to delete.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - Incorrect folder was specified.
• APIERR_NOPLAN - There is no open project.
• APIERR_NOACCESSRIGHT - User has no permission to delete folders under folder.typeID.
• APIERR_NOTMINE - Attribute type folder.typeID is not reserved.

Remarks

Folder has to be an existing folder identified by it's typeID, and path or guid.. Deletes all deletable attributes and folders the given folder contains. If an attribute is not deletable, the folders containing the attribute are not deleted. newName has to be legal, must not be empty, and must not begin or end with whitespace. Renames the specified folder (while preserving it's guid). The root folder can't be renamed, two folders in the same parent folder can't have the same name.

Example

API_AttributeFolder lineFolder {};
lineFolder.typeID = API_LinetypeID;
lineFolder.path = { "A", "B", "C" };
ACAPI_Attribute_DeleteFolder (lineFolder);
 
API_AttributeFolder cwFolder {};
cwFolder.typeID = API_CompWallID;
cwFolder.guid = GS::Guid ("27075EFF-611F-4B11-9BBB-553AC8BDA922");
ACAPI_Attribute_DeleteFolder (cwFolder);

ACAPI_Attribute_DeleteMore()

GSErrCode ACAPI_Attribute_DeleteMore	(	API_AttrTypeID	attrTypeID,
		const GS::Array< API_AttributeIndex > &	attrIndexList
	)

Deletes more attributes of the same type.

Since

Archicad 26

Parameters

attrTypeID	[in] Identifies the type of the attributes to delete.
attrIndexList	[in] List of attribute indices to be deleted.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - The passed parameter attrTypeID is invalid or the given attrIndexList is empty.
• APIERR_REFUSEDPAR - You tried to delete pens, fonts, a solid or an empty fill, or an attribute with index 1.
• APIERR_NOTMINE - The attribute is out of the users workspace.

Remarks

This function is the extension of ACAPI_Attribute_Delete. You can specify a list of attribute indices to be deleted. If you pass only one index in the attrIndexList parameter, this function works like ACAPI_Attribute_Delete. This function is a non-undoable data structure modifier function. See more details on this topic at Command Overview.

Example

GSErrCode err = ACAPI_Attribute_DeleteMore (API_LinetypeID, { 3, 4, 5 });
if (err != NoError) {
    // failed to delete the attributes
}

ACAPI_Attribute_EnumerateAttributesByType()

GSErrCode ACAPI_Attribute_EnumerateAttributesByType	(	API_AttrTypeID	typeID,
		const std::function< void(API_Attribute &)> &	processor
	)

Iterates the instances of a given attribute type in the database.

Since

October 18, 2022

Parameters

typeID	[in] Type of the attribute.
processor	[in] The enumerator process on the API_Attribute as a lambda function.

Returns

ACAPI_Attribute_Get()

GSErrCode ACAPI_Attribute_Get

(

API_Attribute *

attribute

)

Retrieves an attribute from the database.

Since

Archicad 27

Parameters

attribute

[in/out] Parameters of the attribute. The type and the index or the name of the attribute must be passed in the typeID and index, or in the typeID and name fields in the attribute header. The data of the attribute is returned in the appropriate fields of the API_Attribute structure.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - The passed parameter (attribute) is nullptr
• APIERR_BADID - The attribute type is invalid
• APIERR_BADINDEX - The attribute index is invalid; if referenced by index
• APIERR_BADNAME - The attribute with the given name doesn't exist; if referenced by name

Remarks

This function is used to retrieve one attribute's data from the database. Beside the typeID, you should specify either the index or the name field of the header. In the latter case, the index field should be set to zero, and the attribute database is searched by name. You may optionally call ACAPI_Attribute_GetDef to get extended information for certain attribute types. The index range is not always continuous; deleted attributes are not purged immediately from the database. Note: The received attributes can have dynamically allocated members depending on the typeID. They should be disposed when they are no more needed.

• API_MaterialID : attribute.material.texture.fileLoc
• API_ModelViewOptionsID : attribute.modelViewOpt.modelViewOpt.gdlOptions Note: Special pen IDs can be used:
• 1000 : returns the color of the grid line
• 1001 : returns the color of the zone stamp
• 1002 : returns the color of the ghost story

	)

Sets the value of a property for multiple attributes. If the property is not available for at least one of the given attribute then returns with an error without changing any property value.

Parameters

property	[in] The new value of the property.
attrHeaders	[in] The array of attributes, that the property should be available for.

Returns

• NoError - The function has completed with success.
• APIERR_BADID - Inexistent property item.
• APIERR_NOACCESSRIGHT - The current user does not have the right to modify the properties of a specified attribute on a teamwork server.
• APIERR_READONLY - Tried to modify a read-only property (for example a property coming from a hotlink).
• APIERR_BADPROPERTY - The property definition is not available for one of the given attributes.

ACAPI_Attribute_Move()

GSErrCode ACAPI_Attribute_Move	(	const GS::Array< API_AttributeFolder > &	foldersToMove,

Moves attributes and attribute folders.

Since

Archicad 26

Parameters

foldersToMove	[in] List of folders to move.
attributesToMove	[in] List of attributes to move.
targetFolder	[in] Target folder, i.e. the new parent of the folders and attributes to move.

Returns

• NoError - The function has completed with success.
• APIERR_BADID - Incorrect typeID was specified.

Remarks

All folders (items of foldersToMove and targetFolder) have to be existing folders. Handling name collisions:

• If there are name collisions, the moved folders will be merged with the colliding folders in targetFolder, like in a filesystem.
• Name collision of folders is case insensitive. An existing folder in targetFolder will not be renamed. E.g. merging 'foo' into an existing 'Foo' keeps the 'Foo' name.
• Name collision between two moved folders will be handled in order of appearance in foldersToMove. E.g. moving 'A/foo' and 'B/Foo' (in this order) to 'Bar' will result in 'Bar/foo', because 'foo' is first created in 'Bar', and then it is not renamed to 'Foo'. foldersToMove and attributesToMove can contain repeated items. Repeated items will be handled as if only the first occurrence would be present in the list. foldersToMove and attributesToMove can contain items which are already under targetFolder. Such items will be left in place. foldersToMove and attributesToMove can contain items which are under a folder to move. Such items will be ignored, as if they would not be on the list, and only the outermost folder will be moved. A folder or attribute cannot be moved out of its attribute type.
