# MFnVectorArrayData

## Base Class

MFnData

## Constants

None.

## Static Methods

None.

## Static Attributes

None.

## Constructors

Signature | Parameters | Description
--- | --- | ---
MFnVectorArrayData() |  | Default constructor. Returns a new MFnVectorArrayData function set with no Maya object attached.
MFnVectorArrayData(object) | object - MObject | Returns a new MFnVectorArrayData function set, with the specified Maya object attached.

## Object Methods

Signature | Parameters | Returns | Description
--- | --- | --- | ---
array() |  | MVectorArray | Returns the encapsulated array as an MVectorArray. For performance reasons the returned array is a live reference to the encapsulated array so changes made to one directly affect the other. The returned array is only valid for as long as the function set retains the same data object. If the function set is destroyed or attached to a different object then the returned array should be discarded. Failure to do so could result in Maya becoming unstable.
copyTo(array) | array - MVectorArray | Reference to self. | Replaces the elements of array with those in the encapsulated array.
create() |  | MObject | Creates a new empty MVector array data object, attaches it to the function set and returns an MObject which references it.
create(array) | array - MVectorArray or sequence of MVectors | MObject | Creates a new MVector array data object, initializes it with the elements from array, attaches it to the function set and returns an MObject which references it.
set(array) | array - MVectorArray or sequence of MVectors | Reference to self. | Replaces the elements in the encapsulated array with those from the supplied array.
set(value, index) | value - MVector index - int | Reference to self. | Sets the value of the index'th array element.

## Object Attributes

None.

## Sequence Support

len() returns the number of elements in the encapsulated array.

Indexing and element assignment are supported. For performance reasons, the MVectors returned by indexing are live references to the corresponding MVector elements in the encapsulated array, so changes made to one affect the other. These returned elements are only valid for as long as the function set retains the same data object. If the function set is destroyed or attached to a different object then the returned MVectors should be discarded. Failure to do so could result in Maya becoming unstable.

Deletion, concatenation, repetition and slicing are not supported.

## Number Support

None.

## Comparison Support

None.
