Class BERTagDecoder

java.lang.Object
  netscape.ldap.ber.stream.BERTagDecoder

public abstract class BERTagDecoder

extends Object

This is an abstract class which should be extended for use by the BERTag class in decoding application specific BER tags. Since different applications may define their own tag, the BER package needs a tag decoder to give hints on how to decode implicitly tagged objects. Each application should extend this decoder.
