#include <MPlugArray.h>

Class Description

Array of MPlugs data type.

This class implements an array of MPlugs. Common convenience functions are available, and the implementation is compatible with the internal Maya implementation so that it can be passed efficiently between plugins and internal maya data structures.

Constructor & Destructor Documentation

MPlugArray ( )

Default constructor.

The instance is set to contain no elements.

MPlugArray ( const MPlugArray & other )

Copy Constructor.

Parameters

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

MPlugArray	(	unsigned int	initialSize,
		const MPlug &	initialValue
	)

Create a new array of MPlugs 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

MPlugArray	(	const MPlug	src[],
		unsigned int	count
	)

NO SCRIPT SUPPORT.

Create a new array of MPlugs and initialize it with the given MPlugs elements.

Parameters

[in]	src	an array of MPlugs
[in]	count	the number of elements in the src array

Member Function Documentation

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

Index operator.

Returns the value of the element at the given index. No range checking is done - valid indices are 0 to length()-1.

Parameters

[in] index the index of the desired element

Returns: The value of the indicated element

MPlugArray & operator= ( const MPlugArray & 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 MPlug &	element,
		unsigned int	index
	)

Sets the value of the indicated element to the indicated MPlug value.

Parameters

[in]	element	the new value for the indicated element
[in]	index	the index of the element that is to be set to the the new value

Returns: MS::kSuccess if the value was set successfully and MS::kFailure otherwise

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

Returns the number of elements in the instance.

Returns: The number of elements in the instance

Examples:: AbcBullet/MayaUtility.cpp, AbcExport/MayaUtility.cpp, AbcImport/CreateSceneHelper.cpp, AbcImport/util.cpp, animExportUtil/animExportUtil.cpp, apiMeshShape/apiMeshSubSceneOverride.cpp, atomImportExport/atomAnimLayers.cpp, atomImportExport/atomCachedPlugs.cpp, atomImportExport/atomFileUtils.cpp, atomImportExport/atomImportExport.cpp, cgFx/cgfxAttrDef.cpp, constraintEvaluator/constraintEvaluator.cpp, createClipCmd/createClipCmd.cpp, D3DViewportRenderer/D3DViewportRenderer.cpp, dagPoseInfoCmd/dagPoseInfoCmd.cpp, dx11Shader/dx11Shader.cpp, DX11ViewportRenderer/DX11ViewportRenderer.cpp, findFileTexturesCmd/findFileTexturesCmd.cpp, findTexturesPerPolygonCmd/findTexturesPerPolygonCmd.cpp, geometryReplicator/geometryReplicator.cpp, glslShader/GLSLShader.cpp, gpuCache/gpuCacheCmd.cpp, gpuCache/gpuCacheMaterialBakers.cpp, gpuCache/gpuCacheUtil.cpp, hwAnisotropicShader_NV20/ShadingConnection.cpp, hwDecalBumpShader_NV20/ShadingConnection.cpp, hwReflectBumpShader_NV20/ShadingConnection.cpp, hwRefractReflectShader_NV20/ShadingConnection.cpp, hwToonShader_NV20/ShadingConnection.cpp, hwUnlitShader/ShadingConnection.cpp, maTranslator/maTranslator.cpp, meshOpCmd/polyModifierCmd.cpp, nodeInfoCmd/nodeInfoCmd.cpp, particleAttrNode/particleAttrNode.cpp, polyRawExporter/polyWriter.cpp, polyX3DExporter/polyWriter.cpp, simpleFluidEmitter/simpleFluidEmitter.cpp, slopeShader/slopeShaderBehavior.cpp, and splitUVCmd/polyModifierCmd.cpp.

MStatus remove ( unsigned int index )

Remove the array element at the given index.

All array elements following the removed element are shifted toward the first element.

Parameters

[in] index index of the element to be removed

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

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

Inserts a new value into the array at the given index.

The initial element at that index, and all following elements, are shifted towards the last. If the array cannot be expanded in size by 1 element, then the insert will fail and the existing array will remain unchanged.

Parameters

[in]	element	the new value to insert into the array
[in]	index	the index of the element to set to the the new value

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

MStatus append ( const MPlug & element )

Adds a new element to the end of the array.

If the array cannot be expanded in size by 1 element, then the append will fail and the existing array will remain unchanged.

Parameters

[in] element the value for the new last element

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

Examples:: affectsNode/affectsNode.cpp, atomImportExport/atomAnimLayers.cpp, atomImportExport/atomCachedPlugs.cpp, meshOpCmd/polyModifierCmd.cpp, and splitUVCmd/polyModifierCmd.cpp.

MStatus copy ( const MPlugArray & 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 ( )

Clear the contents of the array.

After this operation the length method will return 0. This does not change the amount of memory allocated to the array, only the number of valid elements in it.

Returns: MS::kSuccess if the operation is successful and MS::kFailure otherwise

Examples:: atomImportExport/atomCachedPlugs.cpp, constraintEvaluator/constraintEvaluator.cpp, meshOpCmd/polyModifierCmd.cpp, and splitUVCmd/polyModifierCmd.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.

MStatus get ( MPlug array[] ) const

NO SCRIPT SUPPORT.

Copy the elements of the array into the given array of MPlugs.

No checking is done to ensure that the destination array of MPlugs is large enough to hold all the elements of the instance.

Parameters

[out] array the array to populate

Returns: MS::kSuccess if the array argument is a non-zero pointer and MS::kFailure otherwise

MPlug & operator[] ( unsigned int index )

NO SCRIPT SUPPORT.

Index operator.

Returns the value of the element at the given index. No range checking is done - valid indices are 0 to length()-1.

Parameters

[in] index the index of the desired element

Returns: The value of the indicated element

const char * className ( )

static

Returns the name of this class.

Returns: The name of this class.
