#include <MStringArray.h>

Class Description

Array of MStrings data type.

This class implements an array of MStrings. 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

MStringArray ( )

Default constructor.

The instance is set to contain no elements.

MStringArray ( const MStringArray & other )

Copy constructor.

Parameters

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

MStringArray	(	const MString	src[],
		unsigned int	count
	)

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

Parameters

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

MStringArray	(	const char *	src[],
		unsigned int	count
	)

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

The MStringArray object then owns the character strings and it is responsible for freeing them. The user is responsible for freeing the original array of pointers to type char.

Parameters

[in]	src	a C++ array of character pointers
[in]	count	the number of elements in the array

MStringArray	(	unsigned int	initialSize,
		const MString &	initialValue
	)

Create a new array of strings 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

Member Function Documentation

MString operator[] ( unsigned int index ) const

Index operator.

Returns the value of the element at the given index. If the index is out of the range 0 - length()-1, returns a NULL string.

Parameters

[in] index the index of the element whose value is to be returned

Returns: The value of the indicated element.

MStringArray & operator= ( const MStringArray & 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 MFnStringArrayData::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 MString &	element,
		unsigned int	index
	)

Sets the value of the indicated element to the indicated 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 operation succeeded
MS::kInvalidParameter index out of range
MS::kFailure operation failed

Examples:: AbcBullet/MayaTransformCollectionWriter.cpp, and AbcExport/MayaMeshWriter.cpp.

MStatus set	(	char *	element,
		unsigned int	index
	)

Sets the value of the indicated element to the indicated char* 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 operation succeeded
MS::kInvalidParameter index out of range
MS::kFailure operation failed

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/NodeIteratorVisitorHelper.cpp, and cgFx/cgfxShaderNode.cpp.

unsigned int length ( ) const

Returns the number of elements in the instance.

Returns: The number of elements in the instance

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 operation succeeded
MS::kInvalidParameter index out of range
MS::kFailure operation failed

Examples:: atomImportExport/atomFileUtils.cpp, cleanPerFaceAssignment/cleanPerFaceAssignmentCmd.cpp, dx11Shader/dx11Shader.cpp, eventTest/eventTest.cpp, gpuCache/gpuCacheUtil.h, and nodeCreatedCBCmd/nodeCreatedCBCmd.cpp.

MStatus insert	(	const MString &	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

Examples:: atomImportExport/atomFileUtils.cpp, dx11Shader/dx11Shader.cpp, dx11Shader/dx11ShaderUniformParamBuilder.cpp, glslShader/GLSLShader.cpp, hlslShader/hlslShader.cpp, and sceneAssembly/assemblyReference.cpp.

MStatus append ( const MString & 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
