Detailed Description

Array of MMatrix data type.

This class implements an array of MMatrix's. 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:: apiMeshShape/apiMeshSubSceneOverride.cpp, basicSkinCluster/basicSkinCluster.cpp, footPrintNode_SubSceneOverride/footPrintNode_SubSceneOverride.cpp, and instancerListCmd/instancerListCmd.cpp.

Constructor & Destructor Documentation

OPENMAYA_MAJOR_NAMESPACE_OPEN MMatrixArray ( )

Default constructor.

The instance is set to contain no elements.

MMatrixArray ( const MMatrixArray & other )

Copy Constructor.

Parameters

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

MMatrixArray ( unsigned initialSize )

Create a new array of MMatrix's of a specified size and initialize all the elements as the identity matrix.

Parameters

[in] initialSize the initial size of the array

Member Function Documentation

const MMatrix & operator[] ( unsigned 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.

MMatrixArray & operator= ( const MMatrixArray & 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 MMatrix &	element,
		unsigned	index
	)

Sets the value of the indicated element to the indicated MMatrix 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 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 length ( ) const

Returns the number of elements in the instance.

Returns: The number of elements in the instance

MStatus remove ( unsigned 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 MMatrix &	element,
		unsigned	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 MMatrix & 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:: apiMeshShape/apiMeshSubSceneOverride.cpp, and basicSkinCluster/basicSkinCluster.cpp.

MStatus copy ( const MMatrixArray & 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

void setSizeIncrement ( unsigned newIncrement )

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

Parameters

[in] newIncrement the new increment

unsigned sizeIncrement ( ) const

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

Returns: The size increment.

MMatrix & operator[] ( unsigned index )

Index operator allowing assignment to an element of the array.

Returns a reference to 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: A reference to the indicated element

MMatrixArray::Iterator begin ( )

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

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

MMatrixArray::Iterator end ( )

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

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

MMatrixArray::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.

MMatrixArray::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.

MMatrixArray::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.

MMatrixArray::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.

[r31, r32, r33, r34] [r41, r42, r43, r44]]

Where "n" is the length of the given MMatrixArray

Parameters

[in]	os	the ostream to print to
[in]	array	the MMatrixArray whose value is to be printed

Returns: The ostream reference, s, provided as the first parameter.
