#include <MObjectArray.h>

List of all members.


Detailed Description

Array of MObjects data type.

This class implements an array of MObjects. 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:

animExportUtil.cpp, apiMeshData.cpp, apiMeshData.h, apiMeshIterator.cpp, apiMeshIterator.h, apiMeshShape.cpp, apiMeshShape.h, apiMeshShapeUI.cpp, apiSimpleShape.cpp, apiSimpleShape.h, apiSimpleShapeIterator.cpp, apiSimpleShapeIterator.h, apiSimpleShapeUI.cpp, cgfxShaderCmd.cpp, cgfxShaderNode.cpp, cgfxShaderNode.h, cleanPerFaceAssignmentCmd.cpp, clusterWeightFunction.cpp, createClipCmd.cpp, cvColorShader.cpp, D3DGeometryItem.cpp, D3DViewportRenderer.cpp, findFileTexturesCmd.cpp, findTexturesPerPolygonCmd.cpp, geometrySurfaceConstraint.cpp, geometrySurfaceConstraint.h, getAttrAffectsCmd.cpp, hairCollisionSolver.cpp, hwManagedTextureShader.cpp, maTranslator.cpp, meshMapUtils.cpp, meshMapUtils.h, meshRemapCmd.cpp, meshRemapTool.h, meshReorderCmd.cpp, meshReorderTool.h, motionTraceCmd.cpp, narrowPolyViewer.h, objExport.cpp, OpenGLViewportRenderer.cpp, polyModifierCmd.cpp, polyWriter.h, and slopeShaderBehavior.cpp.

Constructor & Destructor Documentation

MObjectArray::MObjectArray (  ) 

Default constructor. The instance is set to contain no elements.

MObjectArray::MObjectArray ( const MObjectArray other  ) 

Copy Constructor.

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

MObjectArray::MObjectArray ( unsigned int  initialSize,
const MObject initialValue = MObject::kNullObj  
)

Create a new array of MObjects 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

MObjectArray::~MObjectArray (  ) 

Class Destructor

MObjectArray::MObjectArray ( const MObject  src[],
unsigned int  count  
)

NO SCRIPT SUPPORT.

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

Parameters:
[in]  src  an array of MObjects
[in]  count  the number of elements in the src array

Member Function Documentation

const MObject & MObjectArray::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 desired element
Returns:
A reference to the indicated element

MStatus MObjectArray::set ( const MObject element,
unsigned int  index  
)

Sets the value of the indicated element to the indicated MObject 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 if the value was set successfully and MS::kFailure otherwise

MStatus MObjectArray::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

unsigned int MObjectArray::length (  )  const

MStatus MObjectArray::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 MObjectArray::insert ( const MObject 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:

MStatus MObjectArray::append ( const MObject 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:

MStatus MObjectArray::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:
true MS::kSuccess the operation is successful and MS::kFailure otherwise
Examples:

void MObjectArray::setSizeIncrement ( unsigned int  newIncrement  ) 

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

Parameters:
[in]  newIncrement  the new increment

unsigned int MObjectArray::sizeIncrement (  )  const

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

Returns:
true if the array argument is a non-zero pointer and false otherwise

MStatus MObjectArray::get ( MObject  array[]  )  const

NO SCRIPT SUPPORT.

Copy the elements of the array into the given array of MObjects. No checking is done to ensure that the destination array of MObjects is large enough to hold all the elements of the instance.

Parameters:
[out]  array  the array to populate
Returns:
MS::kSuccess if the array argument is a non-zero pointer and MS::kFailure otherwise

MObject & MObjectArray::operator[] ( unsigned int  index  ) 

NO SCRIPT SUPPORT.

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
