Detailed Description

Array of MPlugs data type.

This class implements an array of MPlugs. 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:

affectsNode.cpp, animExportUtil.cpp, animExportUtil.h, apiMeshShape.cpp, apiMeshShape.h, cgfxAttrDef.cpp, createClipCmd.cpp, D3DViewportRenderer.cpp, dagPoseInfoCmd.cpp, exportJointClusterDataCmd.cpp, findFileTexturesCmd.cpp, findTexturesPerPolygonCmd.cpp, GLSLShaderNode.cpp, maTranslator.cpp, nodeInfoCmd.cpp, particleAttrNode.cpp, polyModifierCmd.cpp, polyWriter.cpp, ShadingConnection.cpp, and slopeShaderBehavior.cpp.

class MPlug

Constructor & Destructor Documentation

Default constructor.

The instance is set to contain no elements.

MPlugArray ( const MPlugArray other)

Copy Constructor.

Parameters:
[in]otherthe array with which to initialize this instance
MPlugArray ( unsigned int  initialSize,
const MPlug initialValue 
)

Create a new array of MPlugs of a specified size and initialize all the elements with the given initial value.

Parameters:
[in]initialSizethe initial size of the array
[in]initialValuethe initial value of each element
MPlugArray ( const MPlug  src[],
unsigned int  count 
)

NO SCRIPT SUPPORT.

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

Parameters:
[in]srcan array of MPlugs
[in]countthe number of elements in the src array

Member Function Documentation

const MPlug & 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]indexthe index of the desired element
Returns:
The value of the indicated element
MPlugArray & operator= ( const MPlugArray 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 MPlug element,
unsigned int  index 
)

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

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 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]lengththe new size of the array
unsigned int length ( ) const
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]indexindex of the element to be removed
Returns:
MS::kSuccess if the remove was successful and MS::kFailure otherwise
MStatus insert ( const MPlug 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]elementthe new value to insert into the array
[in]indexthe 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 MPlug 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
Examples:
affectsNode.cpp, and polyModifierCmd.cpp.
MStatus copy ( const MPlugArray 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.

Returns:
MS::kSuccess if the operation is successful and MS::kFailure otherwise
Examples:
polyModifierCmd.cpp.
void setSizeIncrement ( unsigned int  newIncrement)

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

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

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

Returns:
The size increment.
MStatus get ( MPlug  array[]) const

NO SCRIPT SUPPORT.

Copy the elements of the array into the given array of MPlugs.

No checking is done to ensure that the destination array of MPlugs is large enough to hold all the elements of the instance.

Parameters:
[out]arraythe array to populate
Returns:
MS::kSuccess if the array argument is a non-zero pointer and MS::kFailure otherwise
MPlug & operator[] ( unsigned int  index)

NO SCRIPT SUPPORT.

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]indexthe index of the desired element
Returns:
The value of the indicated element
const char * className ( ) [static]

Returns the name of this class.

Returns:
The name of this class.
