MMaterialArray Class Reference

#include <MMaterialArray.h>

Class Description

Array of pointers of MMaterial data type.

This class implements an array of MMaterial. 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

Default constructor.

The instance is set to contain no elements.

MMaterialArray ( const MMaterialArray other)

Copy Constructor.

Parameters
[in]otherthe array with which to initialize this instance

Member Function Documentation

const MMaterial operator[] ( unsigned  index) const

Returns the value of the element at the given index.

No range checking is done - valid indices are 0 to length()-1.

Parameters
[in]indexthe index of the element whose value is to be returned
Returns
The value of the indicated element.
MMaterialArray & operator= ( const MMaterialArray 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]otherthe array being copied
Returns
A reference to this array
MStatus set ( const MMaterial element,
unsigned  index 
)

Sets the value of the indicated element to the indicated MMaterial 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]elementthe new value for the indicated element
[in]indexthe 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]lengththe 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]indexindex of the element to be removed
Returns
MS::kSuccess if the remove was successful and MS::kFailure otherwise
MStatus insert ( const MMaterial 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]elementthe new value to insert into the array
[in]indexthe index of the element to set to the the new value
Returns
true if the insert was successful and false otherwise
MStatus append ( const MMaterial 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]elementthe value for the new last element
Returns
MS::kSuccess if the append was successful and MS::kFailure otherwise
MStatus copy ( const MMaterialArray source)

Copy the contents of the source array to this array.

Parameters
[in]sourcearray 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.

void setSizeIncrement ( unsigned  newIncrement)

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

Parameters
[in]newIncrementthe new increment
unsigned sizeIncrement ( ) const

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

Returns
The size increment.
MMaterial operator[] ( unsigned  index)

Returns the value of the element at the given index.

No range checking is done - valid indices are 0 to length()-1.

Parameters
[in]indexthe index of the element whose value is to be returned
Returns
The value of the indicated element.
const char * className ( )
static

NO SCRIPT SUPPORT.

Returns the name of this class.

Returns
The name of this class.
