Detailed Description

Array of MVectors data type.

This class implements an array of MVectors. 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.

Examples:: AbcExport/MayaPointPrimitiveWriter.cpp, AbcImport/MeshHelper.cpp, AbcImport/NodeIteratorVisitorHelper.cpp, AbcImport/PointHelper.cpp, apiMeshShape/apiMeshCreator.cpp, apiMeshShape/apiMeshCreator.h, apiMeshShape/apiMeshGeom.h, apiMeshShape/apiMeshShape.cpp, apiMeshShape/apiMeshShape.h, dynExprField/dynExprField.cpp, dynExprField/dynExprField.h, geometryCacheConverter/geometryCacheBlockDVAData.cpp, geometryCacheConverter/geometryCacheBlockDVAData.h, geometryCacheConverter/geometryCacheBlockFVAData.cpp, geometryCacheConverter/geometryCacheBlockFVAData.h, hairCollisionSolver/hairCollisionSolver.cpp, ownerEmitter/ownerEmitter.cpp, ownerEmitter/ownerEmitter.h, particleAttrNode/particleAttrNode.cpp, particlePathsCmd/particlePathsCmd.cpp, particleSystemInfoCmd/particleSystemInfoCmd.cpp, pfxInfoCmd/pfxInfoCmd.cpp, simpleEmitter/simpleEmitter.cpp, simpleEmitter/simpleEmitter.h, simpleFluidEmitter/simpleFluidEmitter.cpp, sweptEmitter/sweptEmitter.cpp, sweptEmitter/sweptEmitter.h, torusField/torusField.cpp, torusField/torusField.h, transformDrawNode/transformDrawNode.cpp, XmlGeometryCache/XmlGeometryCache.cpp, and XmlGeometryCacheDesc/XmlGeometryCacheDesc.cpp.

[in]	initialValue	the initial value of each element

Member Function Documentation

const MVector & 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 element whose value is to be returned

Returns: The value of the indicated element.

MVectorArray & operator= ( const MVectorArray & 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 (eg MFnVectorArrayData::array), 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 MVector &	element,
		unsigned int	index
	)

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

NOTE: This method does not grow the array if the index is out of bounds. Only a valid index should be used.

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

Examples:: XmlGeometryCache/XmlGeometryCache.cpp, and XmlGeometryCacheDesc/XmlGeometryCacheDesc.cpp.

MStatus set	(	double	element[3],
		unsigned int	index
	)

Sets the value of the indicated element to the indicated double array value.

NOTE: This method does not grow the array if the index is out of bounds. Only a valid index should be used.

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 set	(	float	element[3],
		unsigned int	index
	)

Sets the value of the indicated element to the indicated float array value.

NOTE: This method does not grow the array if the index is out of bounds. Only a valid index should be used.

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

Examples:: particleAttrNode/particleAttrNode.cpp, particleSystemInfoCmd/particleSystemInfoCmd.cpp, simpleFluidEmitter/simpleFluidEmitter.cpp, XmlGeometryCache/XmlGeometryCache.cpp, and XmlGeometryCacheDesc/XmlGeometryCacheDesc.cpp.

unsigned int length ( ) const

Returns the number of elements in the instance.

Returns: The number of elements in the instance

Examples:: dynExprField/dynExprField.cpp, hairCollisionSolver/hairCollisionSolver.cpp, ownerEmitter/ownerEmitter.cpp, particlePathsCmd/particlePathsCmd.cpp, particleSystemInfoCmd/particleSystemInfoCmd.cpp, pfxInfoCmd/pfxInfoCmd.cpp, simpleEmitter/simpleEmitter.cpp, simpleFluidEmitter/simpleFluidEmitter.cpp, sweptEmitter/sweptEmitter.cpp, torusField/torusField.cpp, XmlGeometryCache/XmlGeometryCache.cpp, and XmlGeometryCacheDesc/XmlGeometryCacheDesc.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 MVector &	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: true if the insert was successful and false otherwise

MStatus append ( const MVector & 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:: AbcImport/MeshHelper.cpp, apiMeshShape/apiMeshCreator.cpp, apiMeshShape/apiMeshShape.cpp, dynExprField/dynExprField.cpp, ownerEmitter/ownerEmitter.cpp, particleSystemInfoCmd/particleSystemInfoCmd.cpp, simpleEmitter/simpleEmitter.cpp, simpleFluidEmitter/simpleFluidEmitter.cpp, sweptEmitter/sweptEmitter.cpp, and torusField/torusField.cpp.

MStatus copy ( const MVectorArray & 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.

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

Examples:: ownerEmitter/ownerEmitter.cpp, simpleEmitter/simpleEmitter.cpp, sweptEmitter/sweptEmitter.cpp, and torusField/torusField.cpp.

MStatus get ( double array[][3] ) const

Copy the elements of the array into the given C++ array of double arrays.

No checking is done to ensure that the destination C++ array of double arrays 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

MStatus get ( float array[][3] ) const

Copy the elements of the array into the given C++ array of float arrays.

No checking is done to ensure that the destination C++ array of floats arrays 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

void setSizeIncrement ( unsigned int newIncrement )

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