#include <MUintArray.h>

Detailed Description

Array of integers data type.

This class implements an array of unsigned 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.

Examples:

: polyMessageCmd.cpp.

Constructor & Destructor Documentation

MUintArray::MUintArray ( )

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

MUintArray::MUintArray ( const MUintArray & other )

Copy Constructor.

Parameters:

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

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

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

Parameters:

`[in]`	src	a C++ array of unsigned ints
`[in]`	count	the number of elements in the src array

MUintArray::MUintArray	(	unsigned int	initialSize,
		unsigned int	initialValue = `0`
	)

Create a new array of unsigned 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

MUintArray::~MUintArray ( )

The class destructor.

Member Function Documentation

MUintArray & MUintArray::operator= ( const MUintArray & other )

Assignment operator copies all of the elements of the other array into this one.

Parameters:

[in] other the array being copied

Returns:: A reference to this array

MStatus MUintArray::set	(	unsigned 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 MUintArray::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 MUintArray::length ( ) const

Returns the number of elements in the instance.

Returns:: The number of elements in the instance

Examples:

: polyMessageCmd.cpp.

MStatus MUintArray::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 MUintArray::insert	(	unsigned 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

MStatus MUintArray::append ( unsigned 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

MStatus MUintArray::copy ( const MUintArray & 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 MUintArray::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

MStatus MUintArray::get ( unsigned int array[] ) const

Copy the elements of the array into the given C++ array of unsigned 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 MUintArray::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 MUintArray::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

unsigned int MUintArray::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.

unsigned int & MUintArray::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

OPENMAYA_EXPORT std::ostream& operator<<	(	std::ostream &	os,
		const MUintArray &	array
	)			`[friend]`

NO SCRIPT SUPPORT.

Print the contents of the given MUintArray on the given ostream. The format used is [1, 2, 3, ... 9].

Parameters:

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

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