#include <MFnArrayAttrsData.h>

Class Description

Function set for multiple arrays of attributes for dependency node data.

MFnArrayAttrsData allows the creation and manipulation of multiple arrays of attributes as a data object over a single connection for use as dependency graph data.

If a user written dependency node either accepts or produces MFnArrayAttrsData, then this class is used to extract or create the data that comes from or goes to other dependency graph nodes. The MDataHandle::type method will return kDynArrayAttrsData when data of this type is present. To access it, the MDataHandle::data() method is used to get an MObject for the data and this should then be used to initialize an instance of MFnArrayAttrsData.

NOTE: these data attributes are not storable.

Examples:: dynExprField/dynExprField.cpp, ownerEmitter/ownerEmitter.cpp, ownerEmitter/ownerEmitter.h, simpleEmitter/simpleEmitter.cpp, simpleEmitter/simpleEmitter.h, simpleFluidEmitter/simpleFluidEmitter.h, sweptEmitter/sweptEmitter.cpp, and sweptEmitter/sweptEmitter.h.

Class constructor that initializes the function set to the given MObject.

Constructor

Parameters

[in]	object	The MObject to attach the function set to
[out]	ReturnStatus	the return status

Status Codes:

MS::kSuccess if the function set is successfully attached
