Detailed Description

int array function set for dependency node data.

MFnIntArrayData allows the creation and manipulation of MIntArray data objects for use in the dependency graph.

If a user written dependency node either accepts or produces MIntArrays, 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 kIntArray 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 MFnIntArrayData.

Examples:: AbcBullet/AttributesWriter.cpp, AbcExport/AttributesWriter.cpp, AbcImport/CreateSceneHelper.cpp, and AbcImport/NodeIteratorVisitorHelper.cpp.

Constructor & Destructor Documentation

MFnIntArrayData	(	MObject &	object,
		MStatus *	ReturnStatus = `NULL`
	)

Constructor.

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

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
MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

MFnIntArrayData	(	const MObject &	object,
		MStatus *	ReturnStatus = `NULL`
	)

Constructor.

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

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
MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

Member Function Documentation

MFn::Type type ( ) const

virtual

Function set type.

Return the class type : MFn::kIntArrayData.

Returns: the class type.

Reimplemented from MFnData.

OPENMAYA_MAJOR_NAMESPACE_OPEN const char * className ( )

static

Returns the name of this class.

Return the class name : "MFnIntArrayData".

Returns: Name of this class.

unsigned int length ( MStatus * ReturnStatus = NULL ) const

Return the number of integers in the instance.

Parameters

[out] ReturnStatus kFailure if the instance is not attached to an MObject, and kSuccess otherwise.

Returns: The number of integers in the instance

Examples:: AbcBullet/AttributesWriter.cpp, and AbcExport/AttributesWriter.cpp.

int operator[] ( unsigned int index ) const

Extract the indicated integer from the const instance.

No checking is done by this class to ensure that the index is valid - use the length method to determine the size of the array. If the instance is not attached to an MObject, this method will return an integer containing zero.

Parameters

[in] index the index of the integer to extract

Returns: The indicated integer

MStatus set	(	int	element,
		unsigned int	index
	)

Set the integer element at the specified index of this array.

No checking is done by this class to ensure that the index is valid - use the length method to determine the size of the array.

Parameters

[in]	element	the element
[in]	index	the index of the integer to extract

Returns

kSuccess operation successful
kFailure instance is not attached to an MObject

MStatus copyTo ( MIntArray & dest ) const

Copy all the integers in the instance into the given MIntArray.

Parameters

[out] dest the MIntArray to populate

Returns

kSuccess operation successful
kFailure instance is not attached to an MObject

MStatus set ( const MIntArray & array )

Set the instance to contain the integers defined in the given MIntArray.

Parameters

[in] array the MIntArray containing the data to set into this instance

Returns

kSuccess operation successful
kFailure instance is not attached to an MObject

MIntArray array ( MStatus * ReturnStatus = NULL )

Return an MIntArray containing the integer array currently operated upon by the function set.

The MIntArray returned by this method is editable, so any changes to the return instance also affects the MObject operated upon by this function set.

Parameters

[out] ReturnStatus kFailure if the instance is not attached to an MObject, and kSuccess otherwise.

Returns: A copy of the MIntArray held in this instance

MObject create ( MStatus * ReturnStatus = NULL )

Create a new MObject, attach it to this instance, and initialize it to contain no ints.

Parameters

[out] ReturnStatus kSuccess

Returns: The newly created MObject

Examples:: AbcImport/NodeIteratorVisitorHelper.cpp.

MObject create	(	const MIntArray &	arr,
		MStatus *	ReturnStatus = `NULL`
	)

Create a new MObject, attach it to this instance, and initialize it to contain the data from the given MIntArray.

Parameters

[in]	arr	the data to use when initializing this instance
[out]	ReturnStatus	kSuccess

Returns: The newly created MObject

int & operator[] ( unsigned int index )

NO SCRIPT SUPPORT.

Extract the indicated integer from the instance.

by the function set. The integer returned by this method is editable, so any changes to the return instance also affects the MObject operated upon by this function set.

No checking is done by this class to ensure that the index is valid - use the length method to determine the size of the array. If the instance is not attached to an MObject, this method will return an integer containing zero.

Parameters

[in] index the index of the integer to extract

Returns: The indicated integer
