netscape.ldap.ber.stream

Class BERBitString

Implemented Interfaces:
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

BERBitString

public BERBitString(InputStream stream,
                    int[] bytes_read)
            throws IOException
Constructs a bitstring element from an input stream (for primitive encodings).

Parameters:
stream - source
bytes_read - array of 1 int; value incremented by number of bytes read from stream

BERBitString

public BERBitString(BERTagDecoder decoder,
                    InputStream stream,
                    int[] bytes_read)
            throws IOException
Constructs a bitstring element from an input stream (for constructed encodings).

Parameters:
stream - source
bytes_read - array of 1 int; value incremented by number of bytes read from stream

Method Details

getSize

public int getSize()
Gets the number of bits.

Returns:
bit numbers.

getType

public int getType()
Gets the element type.
Overrides:
getType in interface BERElement

Parameters:

getValue

public BitSet getValue()
Gets the bitstring value.

Parameters:

toString

public String toString()

string representation of tag.

write

public void write(OutputStream stream)
            throws IOException
Sends the BER encoding directly to a stream. Always sends in primitive form.
Overrides:
write in interface BERElement

Parameters:
stream - output stream
