netscape.ldap.ber.stream

Class BERBitString

java.lang.Object

netscape.ldap.ber.stream.BERElement

netscape.ldap.ber.stream.BERBitString

All Implemented Interfaces:

java.io.Serializable

public class BERBitString
extends BERElement

This class is for the BitString object. Note that the BitSet class has a bug: size() returns the size of the internal allocated memory rather than the number of bits. Current work-around is to maintain the number of bits ourselves in m_value_num_bits. Change is required when BitSet is fixed.

 ENCODING RULE:
   Primitive Definite length.
   tag = 0x03
