MStatus setCompleteData ( MUint64 numElements )

Search for all occurrences

Marks the component as complete (meaning all items are selected) and uses the argument to identify the total number of elements selected.

If the component should contain N element indices, then the range would be [0,N-1].

Also sets the complete state of the component to 'true' (i.e. setComplete(true)).

Parameters:

[in] numElements the maximum number of elements in the component

Returns:: Status code

Status Codes:

MS::kSuccess the method was successful
MS::kFailure an object error has occurred

MStatus getCompleteData ( MUint64 & numElements ) const

Search for all occurrences

Returns the number of elements for the complete component.

A complete component means that all elements are selected.

Parameters:

[out] numElements storage for the maximum number of elements

Returns:: Status code

Status Codes:

MS::kSuccess the method was successful
MS::kFailure an object error has occurred
