Detailed Description

Indexable Array of DAG Paths.

Provides methods for manipulating arrays of DAG Paths.

Arrays of DAG Paths are useful for storing and manipluating multiple Paths to a particular DAG Node. The DAG Path method MDagPath::getAllPathsTo() and DAG Node Function Set method MFnDagNode::getAllPaths() implicitly return an array of DAG Paths.

These arrays may also be used to manage Paths for a number of different Nodes.

DAG Path arrays are used in conjunction with DAG Paths (MDagPath) and individual elements of the arrays can be parameters to some methods of the DAG Node Function Set (MFnDagNode).

Use this DAG Path Array Class to create and manipulate arrays of DAG Paths, for either a particular DAG Node or a number of different DAG Nodes.

The length of the array adjusts automatically.

Examples:: AbcExport/MayaNurbsCurveWriter.cpp, AbcExport/MayaNurbsCurveWriter.h, apiMeshShape/apiMeshSubSceneOverride.cpp, apiMeshShape/apiMeshSubSceneOverride.h, exampleCameraSetView/exampleCameraSetViewCmd.h, exportSkinClusterDataCmd/exportSkinClusterDataCmd.cpp, footPrintNode_SubSceneOverride/footPrintNode_SubSceneOverride.cpp, gpuCache/gpuCacheSubSceneOverride.cpp, gpuCache/gpuCacheSubSceneOverride.h, instancerListCmd/instancerListCmd.cpp, listLightLinksCmd/listLightLinksCmd.cpp, maTranslator/maTranslator.cpp, narrowPolyViewer/narrowPolyViewer.cpp, narrowPolyViewer/narrowPolyViewer.h, narrowPolyViewer/narrowPolyViewerCmd.h, skinClusterWeights/skinClusterWeights.cpp, and testCameraSetCmd/testCameraSetCmd.cpp.

Constructor & Destructor Documentation

OPENMAYA_MAJOR_NAMESPACE_OPEN MDagPathArray ( )

Class Constructor.

Creates a DAG Path Array

MDagPathArray ( const MDagPathArray & other )

Copy Constructor.

Parameters

[in] other the array with which to initialize this instance

MDagPathArray	(	unsigned int	initialSize,
		const MDagPath &	initialValue
	)

Create a new array of MDagPaths of a specified size and initialize all the elements with the given initial value.

Parameters

[in]	initialSize	the initial size of the array
[in]	initialValue	the initial value of each element

~MDagPathArray ( )

Class Destructor.

No additional action.

Member Function Documentation

const MDagPath & operator[] ( unsigned int index ) const

Retrieves the read-only DAG Path which is at the specified index in the array.

Parameters

[in] index Zero-based index to the array

Returns: DAG Path at the specified index

MDagPathArray & operator= ( const MDagPathArray & other )

Assignment operator copies all of the elements of the other array into this one.

If the other array was returned as a reference to internal data then this array will also become a reference rather than doing a full copy.

Parameters

[in] other the array being copied

Returns: A reference to this array

MStatus set	(	const MDagPath &	element,
		unsigned int	index
	)

Sets an element of the array to the given DAG path.

Parameters

[in]	element	New DAG path to be set on the indicated element
[in]	index	Zero-based index to the array

Returns: MS::kSuccess on success, otherwise MS::kFailure

MStatus setLength ( unsigned int length )

Set the length of the array.

This will grow and shrink the array as desired. Elements that are grown have uninitialized values, while those which are shrunk will lose the data contained in the deleted elements (ie. it will release the memory).

Parameters

[in] length the new size of the array

unsigned int length ( ) const

Determines the number of elements in the array.

Returns: Number of elements in the array

Examples:: apiMeshShape/apiMeshSubSceneOverride.cpp, gpuCache/gpuCacheSubSceneOverride.cpp, listLightLinksCmd/listLightLinksCmd.cpp, narrowPolyViewer/narrowPolyViewer.cpp, and skinClusterWeights/skinClusterWeights.cpp.

MStatus remove ( unsigned int index )

Removes the DAG Path which is at the specified index in the array.

Parameters

[in] index Zero-based index to the array

Returns: MS::kSuccess on success, otherwise MS::kFailure

MStatus insert	(	const MDagPath &	element,
		unsigned int	index
	)

Inserts the given DAG Path at the specified index in the array.

Parameters

[in]	element	DAG Path to be inserted
[in]	index	Zero-based index to the array

Returns: MS::kSuccess on success, otherwise MS::kFailure

MStatus append ( const MDagPath & element )

Appends the given DAG Path to the end of the array.

Parameters

[in] element DAG Path to be appended

Returns: MS::kSuccess on success, otherwise MS::kFailure

Examples:: AbcExport/MayaNurbsCurveWriter.cpp, narrowPolyViewer/narrowPolyViewer.cpp, and testCameraSetCmd/testCameraSetCmd.cpp.

MStatus copy ( const MDagPathArray & source )

Copy the contents of the source array to this array.

Parameters

[in] source array to copy from

Returns: MS::kSuccess if the copy was successful and MS::kFailure otherwise

MStatus clear ( )

Clears this array.

Length of the array becomes zero.

Returns: MS::kSuccess on success, otherwise MS::kFailure

Examples:: listLightLinksCmd/listLightLinksCmd.cpp, and narrowPolyViewer/narrowPolyViewer.cpp.

void setSizeIncrement ( unsigned int newIncrement )

Set the size by which the array will be expanded whenever expansion is necessary.

Parameters

[in] newIncrement the new increment

unsigned int sizeIncrement ( ) const

Return the size by which the array will be expanded whenever expansion is necessary.

Returns: The size increment.

MDagPath & operator[] ( unsigned int index )

Retrieves the DAG Path which is at the specified index in the array.

Parameters

[in] index Zero-based index to the array

Returns: DAG Path at the specified index

MDagPathArray::Iterator begin ( )

Returns an iterator object pointed to the beginning of the array.

Returns: Iterator object pointed to the beginning of the array.

MDagPathArray::Iterator end ( )

Returns an iterator object pointed to the end of the array.

Returns: Iterator object pointed to the end of the array.

MDagPathArray::ConstIterator begin ( ) const

Returns a const iterator object pointed to the beginning of the array.

Returns: Iterator object pointed to the beginning of the array.

MDagPathArray::ConstIterator end ( ) const

Returns a const iterator object pointed to the end of the array.

Returns: Iterator object pointed to the end of the array.

MDagPathArray::ConstIterator cbegin ( ) const

Returns a const iterator object pointed to the beginning of the array.

Returns: Iterator object pointed to the beginning of the array.

MDagPathArray::ConstIterator cend ( ) const

Returns a const iterator object pointed to the end of the array.

Returns: Iterator object pointed to the end of the array.

const char * className ( )

static

Returns the name of this class.

Returns: The name of this class.
