Constructor & Destructor Documentation

OPENMAYA_MAJOR_NAMESPACE_OPEN MAttributeSpecArray

(

)

Default constructor.

The array is set to contain no elements.

MAttributeSpecArray

(

const MAttributeSpecArray &

other

)

Copy Constructor.

Parameters

[in]

other

the array with which to initialize this array

MAttributeSpecArray	(	unsigned int	initialSize,
		const MAttributeSpec &	initialValue
	)

Create a new array of MAttributeSpecs 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

Member Function Documentation

MAttributeSpec operator[]

(

unsigned int

index

)

const

Index operator.

Returns the value of the element at the given index. Valid indices are 0 to length()-1.

Parameters

[in]

index

the index of the element to return

Returns

A reference to the specified element

MAttributeSpecArray & operator=

(

const MAttributeSpecArray &

other

)

Assignment operator.

Parameters

[in]

other

The source object to assign from.

Returns

A reference to the copied MAttributeSpecArray object.

MStatus set	(	const MAttributeSpec &	element,
		unsigned int	index
	)

Sets the value of the specified element to the given attribute spec.

Parameters

[in]	element	the new value for the specified element
[in]	index	the index of the element to be set

Returns

• MS::kSuccess the value was set successfully
• MS::kFailure invalid index

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]

length

the new size of the array

Returns

• MS::kSuccess the method is successful.
• MS::kFailure the method failed.

unsigned int length

(

)

const

Returns the number of elements in the array.

Returns

The number of elements in the array

Examples:

MStatus remove

(

unsigned int

index

)

Removes the element in the array at the given index.

Parameters

[in]

index

the index of the element to removed

Returns

• MS::kSuccess the remove was successful.
• MS::kInvalidParameter when the specified index is out of range.
• MS::kFailure the remove failed

MStatus insert	(	const MAttributeSpec &	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.

Parameters

[in]	element	the new value to insert into the array
[in]	index	the index of the element to set

Returns

• MS::kSuccess the insert was set successfully
• MS::kFailure the insert failed

MStatus append

(

const MAttributeSpec &

element

)

Adds a new element to the end of the array.

Parameters

[in]

element

the value for the new last element

Returns

• MS::kSuccess the append was set successfully
• MS::kFailure the append failed

MStatus copy

(

const MAttributeSpecArray &

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 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 the operation was set successfully
• MS::kFailure the operation failed

void 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 sizeIncrement

(

)

const

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

Returns

The size increment.

const char * className ( )

static

Returns the name of this class.

Returns

The name of this class.
