Detailed Description

Data interface for controlling a copy stream. Copy streams are sometimes used

to copy the data out of an object, into a stream, or to instantiate an object

that was copied out. This is very low level functionality; look in ScrapUtils

to see if that can meet your needs before using copy streams. Even if you do

need a copy stream, normally you can get the stream from StreamUtil instead of

setting it up yourself. This interface is only useful if you get passed a stream

and need to know what its target is.
