public abstract class StreamBasedCMap
A stream based mapping from character codes to CID's.
The data in the stream defines the mapping from character codes to a font number and a character selector. The data must follow the syntax defined in Adobe Technical Note #5014, Adobe CMap and CIDFont Files Specification.
