Detailed Description

Array of integers data type.

This class implements an array of integers. 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

MIntArray::MIntArray (  ) 

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

MIntArray::MIntArray ( const MIntArray &  other  ) 

Copy Constructor.

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

MIntArray::MIntArray ( const int  src[],
unsigned int  count  
)

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

Parameters:
[in]  src  a C++ array of ints
[in]  count  the number of elements in the src array

MIntArray::MIntArray ( unsigned int  initialSize,
int  initialValue = 0  
)

Create a new array of integers 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

MIntArray::~MIntArray (  ) 

The class destructor.

Member Function Documentation

MIntArray & MIntArray::operator= ( const MIntArray &  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 MFnIntArrayData::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 MIntArray::set ( int  element,
unsigned int  index  
)

Sets the value of the indicated element to the indicated 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 MIntArray::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:
cgfxShaderNode.cpp, flipUVCmd.cpp, and polyWriter.cpp.

unsigned int MIntArray::length (  )  const

Returns the number of elements in the instance.

Returns:
The number of elements in the instance
Examples:
apiMeshCreator.cpp, blindDataShader.cpp, cleanPerFaceAssignmentCmd.cpp, convertEdgesToFacesCmd.cpp, convertVerticesToEdgesCmd.cpp, convertVerticesToFacesCmd.cpp, flipUVCmd.cpp, meshMapUtils.cpp, meshOpFtyAction.cpp, meshRemapCmd.cpp, meshReorderCmd.cpp, objExport.cpp, ownerEmitter.cpp, particlePathsCmd.cpp, particleSystemInfoCmd.cpp, polyRawWriter.cpp, polyX3DWriter.cpp, simpleEmitter.cpp, splitUVCmd.cpp, sweptEmitter.cpp, testNobjectNode.cpp, and volumeLightCmd.cpp.

MStatus MIntArray::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
Examples:
cleanPerFaceAssignmentCmd.cpp, meshMapUtils.cpp, and nodeCreatedCBCmd.cpp.

MStatus MIntArray::insert ( int  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:
animExportUtil.cpp.

MStatus MIntArray::append ( int  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:
animExportUtil.cpp, apiMeshCreator.cpp, blindDataMesh.cpp, cleanPerFaceAssignmentCmd.cpp, meshMapUtils.cpp, meshOpFtyAction.cpp, meshOpNode.cpp, meshRemapCmd.cpp, nodeCreatedCBCmd.cpp, objExport.cpp, ownerEmitter.cpp, particlePathsCmd.cpp, pluginMain.cpp, polyModifierCmd.cpp, shellNode.cpp, simpleEmitter.cpp, splitUVCmd.cpp, splitUVFtyAction.cpp, splitUVNode.cpp, sweptEmitter.cpp, and volumeLightCmd.cpp.

MStatus MIntArray::copy ( const MIntArray &  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 MIntArray::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.

Examples:
apiMeshCreator.cpp, cleanPerFaceAssignmentCmd.cpp, listPolyHolesCmd.cpp, meshMapUtils.cpp, meshRemapCmd.cpp, nodeCreatedCBCmd.cpp, ownerEmitter.cpp, simpleEmitter.cpp, sweptEmitter.cpp, and volumeLightCmd.cpp.

MStatus MIntArray::get ( int  array[]  )  const

Copy the elements of the array into the given C++ array of ints. No checking is done to ensure that the destination C++ array of ints 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

void MIntArray::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 MIntArray::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

int & MIntArray::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

int MIntArray::operator[] ( unsigned int  index  )  const

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]  index  the index of the element whose value is to be returned
Returns:
The value of the indicated element.
