Package crosby.binary

Class BinarySerializer

java.lang.Object

crosby.binary.BinarySerializer

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public class BinarySerializer
extends Object
implements Closeable, Flushable

Generic serializer common code Serialize a set of blobs and process them. Subclasses implement handlers for different API's (osmosis, mkgmap, splitter, etc.) All data is converted into PrimGroupWriterInterface objects, which are then ordered to process their data at the appropriate time.
