Object Methods

SignatureParametersReturnsDescription
array()   MDoubleArray Returns the encapsulated array as an MDoubleArray. 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 - MDoubleArray Reference to self. Replaces the elements of array with those in the encapsulated array.
create()   MObject Creates a new, empty double array data object, attaches it to the function set and returns an MObject which references it.
create(array) array - MDoubleArray or sequence of floats MObject Creates a new, double 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 - MDoubleArray or sequence of floats Reference to self. Replaces the elements in the encapsulated array with those from the supplied array.
set(value, index) value - float
index - int
Reference to self. Sets the value of the index'th element of the array.

Object Attributes

None.

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

Indexing and element assignment are supported. Element values are treated as Python floats.

Deletion, concatenation, repetition and slicing are not supported.

Number Support

None.
