Class ASN1BitString

java.lang.Object
oracle.security.crypto.asn1.ASN1BitString

All Implemented Interfaces:

ASN1Object, ASN1TaggedObject, Streamable

public class ASN1BitString

extends java.lang.Object

implements ASN1TaggedObject

The universal ASN.1 bit string type.

The input may be any valid BER encoding of an ASN.1 bit string. The output is always a DER encoding.

Constructor Summary

ASN1BitString()

ASN1BitString(java.math.BigInteger v)
Creates a new bit string from the given integer value.

ASN1BitString(byte[] value)

ASN1BitString(byte[] value, int unused)

ASN1BitString(java.io.InputStream is)

ASN1BitString(int nBits)
Creates a new ASN.1 bit string of the specified number of bits.

Method Summary

int	bitLength()
void	clearBit(int n) Clears the specified bit.
ASN1Header	getHeader()
int	getUnused()
byte[]	getValue()
void	input(java.io.InputStream is) Inputs this object from the specified input stream.
static byte[]	inputValue(java.io.InputStream is)
int	intValue()
int	length() Length of this object's encoding.
void	output(java.io.OutputStream os) Outputs this object to the specified output stream.
static void	outputValue(java.io.OutputStream os, byte[] value)
static void	outputValueWithTag(java.io.OutputStream os, byte[] value, int tag)
void	setBit(int n) Sets the specified bit.
boolean	testBit(int n) Tests the specified bit.

Constructor Detail

ASN1BitString

public ASN1BitString()

ASN1BitString

public ASN1BitString(byte[] value)

ASN1BitString

public ASN1BitString(byte[] value,
                     int unused)

ASN1BitString

public ASN1BitString(int nBits)

Creates a new ASN.1 bit string of the specified number of bits. Initially all bits are zero.

ASN1BitString

public ASN1BitString(java.math.BigInteger v)

Creates a new bit string from the given integer value.

The new bit string is obtained from the binary expansion of n, most significant bit first, not including the sign bit.
