DERBitString

public DERBitString(byte[] data,
                    int padBits)

padBits - the number of extra bits at the end of the string.

DERBitString

public DERBitString(byte[] data)

DERBitString

public DERBitString(DEREncodable obj)
Method Detail

getPadBits

protected static int getPadBits(int bitString)
return the correct number of pad bits for a bit string defined in a 16 bit constant


getBytes

protected static byte[] getBytes(int bitString)
return the correct number of bytes for a bit string defined in a 16 bit constant


getInstance

public static DERBitString getInstance(java.lang.Object obj)
return a Bit String from the passed in object

Throws:
java.lang.IllegalArgumentException - if the object cannot be converted.

getInstance

public static DERBitString getInstance(ASN1TaggedObject obj,
                                       boolean explicit)
return a Bit String from a tagged object.

Parameters:
obj - the tagged object holding the object we want
explicit - true if the object is meant to be explicitly tagged false otherwise.
Throws:
java.lang.IllegalArgumentException - if the tagged object cannot be converted.

getBytes

public byte[] getBytes()

getPadBits

public int getPadBits()

equals

public boolean equals(java.lang.Object o)
Overrides:
equals in class java.lang.Object
