com.ibm.as400.access.ConvTableWriter
public class ConvTableWriter extends OutputStreamWriter
A ConvTableWriter represents a Toolbox converter that uses stateful character conversion. That is, it wraps an underlying OutputStream and caches/writes the appropriate number of bytes for the given Unicode characters and CCSID/encoding. This is especially useful when converting Strings and characters to a mixed-byte CCSID, and you don't want to have to keep track of which shift state the conversion stream is in between writes.
