// CLASS DESCRIPTION (MDataBlock)
|
|
//
|
|
// An MDataBlock provides storage for the data being received by or sent by
|
|
// the node. It is the data for the plugs and attributes of the node. The
|
|
// data block is only valid during the compute method of the depend node,
|
|
// and should not be stored.
|
|
//
|
|
// Access to the data in an MDataBlock is done using an MDataHandle or an
|
|
// MArrayDataHandle.
