|
|
// CLASS DESCRIPTION (MArrayDataHandle)
|
|
//
|
|
// An MArrayDataHandle is a smart pointer into a data block (MDataBlock) that
|
|
// handles access to array data. MArrayDataHandle supports attributes that
|
|
// can have an array of data.
|
|
//
|
|
// The array indices do not have to be continuous. The array can be sparse.
|
|
// Thus, an array could have four elements with the indicies 1, 6, 8, and 10.
