// CLASS DESCRIPTION (MDataHandle)
|
|
//
|
|
// An MDataHandle is a smart pointer into a data block (MDataBlock). A data
|
|
// handle corresponds to the data for a particular attribute or plug. For
|
|
// array data (eg CVs of a curve) use an MArrayDataHandle. To get a data
|
|
// handle, request it from the data block.
