Class CodeSetConversion

java.lang.Object

com.sun.corba.ee.impl.encoding.CodeSetConversion

public class CodeSetConversion
extends Object

Collection of classes, interfaces, and factory methods for CORBA code set conversion. This is mainly used to shield other code from the sun.io converters which might change, as well as provide some basic translation from conversion to CORBA error exceptions. Some extra work is required here to facilitate the way CORBA says it uses UTF-16 as of the 00-11-03 spec. REVISIT - Since the nio.Charset and nio.Charset.Encoder/Decoder use NIO ByteBuffer and NIO CharBuffer, the interaction and interface between this class and the CDR streams should be looked at more closely for optimizations to avoid unnecessary copying of data between char[] & CharBuffer and byte[] & ByteBuffer, especially DirectByteBuffers.
