- public class ConvTableReader
- extends java.io.InputStreamReader
Internal class representing a Toolbox converter that uses
stateful character conversion. That is, it wraps an underlying
InputStream and reads/caches the appropriate number of bytes
to return the requested number of Unicode characters. This is
especially useful for mixed byte tables where the number of
converted Unicode characters is almost never the same as the number of
underlying EBCDIC bytes. This class exists primarily for the use
of the IFSText classes, but other components are free to use it
as well.

- Reads up to length characters out of the underlying stream.
- Parameters:
length
- The number of Unicode characters to return as a String. The
number of bytes read from the underlying InputStream can be greater than
length.- Returns:
- A String of up to length Unicode characters, or null if the end of the
stream has been reached. The actual number of
characters returned may be less than the specified length if the end of
the underlying InputStream is reached while reading.
