Detailed Description

Array of MFloatPoint data type.

This class implements an array of MFloatPoints. 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/MayaMeshWriter.cpp, AbcImport/AlembicNode.cpp, AbcImport/MeshHelper.cpp, animCubeNode/animCubeNode.cpp, blindDataShader/blindDataMesh.cpp, gpuCache/CacheReaderAlembic.cpp, gpuCache/gpuCacheDrawOverride.cpp, gpuCache/gpuCacheUtil.h, hairCollisionSolver/hairCollisionSolver.cpp, hwPhongShader/hwPhongShader.cpp, intersectCmd/intersectCmd.cpp, meshOpCmd/meshOpFtyAction.cpp, narrowPolyRenderOverride/narrowPolyRenderOverride.cpp, polyPrimitiveCmd/polyPrimitiveCmd.cpp, sampleCmd/sampleCmd.cpp, sampleParticles/sampleParticles.cpp, shellNode/shellNode.cpp, sseDeformer/sseDeformer.cpp, testNobjectNode/testNobjectNode.cpp, testNpassiveNode/testNpassiveNode.cpp, testNucleusNode/testNucleusNode.cpp, threadedBoundingBox/threadedBoundingBox.cpp, uiDrawManager/uiDrawManager.cpp, and viewRenderOverride/viewRenderOverrideOperations.cpp.

Member Function Documentation

const MFloatPoint & 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.

MFloatPointArray & operator= ( const MFloatPointArray & 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 MFloatPoint &	element,
		unsigned int	index
	)

Sets the value of the indicated element to the indicated 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:: AbcImport/MeshHelper.cpp.

MStatus set	(	unsigned int	index,
		float	x,
		float	y,
		float	z = `0`,
		float	w = `1`
	)

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

The x component of the element is set to x, the y component to y, the z component to z, and the w component to w.

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

Parameters

[in]	index	the index of the element that is to be set to the the new value
[in]	x	the new value for the x component
[in]	y	the new value for the y component
[in]	z	the new value for the z component,defaulted to 0
[in]	w	the new value for the w component,defaulted to 1

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

MStatus set	(	float	val[4],
		unsigned int	index
	)

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

The x component of the element is set to val[0], the y component to val[1], the z component to val[2], and the w component to val[3].

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

Parameters

[in]	val	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	(	double	val[4],
		unsigned int	index
	)

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

The x component of the element is set to val[0], the y component to val[1], the z component to val[2], and the w component to val[3].

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

Parameters

[in]	val	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:: AbcImport/MeshHelper.cpp, gpuCache/CacheReaderAlembic.cpp, testNobjectNode/testNobjectNode.cpp, and testNpassiveNode/testNpassiveNode.cpp.

unsigned int length ( ) const

Returns the number of elements in the instance.

Returns: The number of elements in the instance

Examples:: AbcExport/MayaMeshWriter.cpp, AbcImport/MeshHelper.cpp, animCubeNode/animCubeNode.cpp, blindDataShader/blindDataMesh.cpp, gpuCache/gpuCacheUtil.h, hairCollisionSolver/hairCollisionSolver.cpp, hwPhongShader/hwPhongShader.cpp, intersectCmd/intersectCmd.cpp, narrowPolyRenderOverride/narrowPolyRenderOverride.cpp, sampleCmd/sampleCmd.cpp, sampleParticles/sampleParticles.cpp, sseDeformer/sseDeformer.cpp, testNobjectNode/testNobjectNode.cpp, testNucleusNode/testNucleusNode.cpp, and threadedBoundingBox/threadedBoundingBox.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 MFloatPoint &	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 MFloatPoint & 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:: animCubeNode/animCubeNode.cpp, blindDataShader/blindDataMesh.cpp, meshOpCmd/meshOpFtyAction.cpp, narrowPolyRenderOverride/narrowPolyRenderOverride.cpp, sampleCmd/sampleCmd.cpp, sampleParticles/sampleParticles.cpp, shellNode/shellNode.cpp, and uiDrawManager/uiDrawManager.cpp.

MStatus append	(	float	x,
		float	y,
		float	z = `0`,
		float	w = `1`
	)

Adds a new element to the end of the array.

The appended element has the indicated values for its x,y,z and w components. The x component of the element is set to x, the y component to y, the z component to z, and the w component to w.

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]	x	the value for the x component
[in]	y	the value for the y component
[in]	z	the value for the z component, defaulted to 0
[in]	w	the value for the w component, defaulted to 1

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

MStatus get ( float dest[][4] ) const
