Package org.bouncycastle.asn1

Class DLBitStringParser

java.lang.Object

org.bouncycastle.asn1.DLBitStringParser

All Implemented Interfaces:

ASN1BitStringParser, ASN1Encodable, InMemoryRepresentable

public class DLBitStringParser
extends java.lang.Object
implements ASN1BitStringParser

Parser for a DL encoded BIT STRING.

Method Summary

Modifier and Type	Method	Description
java.io.InputStream	getBitStream()	Return an InputStream representing the contents of the BIT STRING.
ASN1Primitive	getLoadedObject()	Get the in-memory representation of the ASN.1 object.
java.io.InputStream	getOctetStream()	Return an InputStream representing the contents of the BIT STRING, where the content is expected to be octet-aligned (this will be automatically checked during parsing).
int	getPadBits()	Return the number of pad bits, if any, in the final byte, if any, read from ASN1BitStringParser.getBitStream().
ASN1Primitive	toASN1Primitive()	Return an object, possibly constructed, of ASN.1 primitives

Method Detail

getBitStream

public java.io.InputStream getBitStream()
                                 throws java.io.IOException

Description copied from interface: ASN1BitStringParser

Return an InputStream representing the contents of the BIT STRING. The final byte, if any, may include pad bits. See ASN1BitStringParser.getPadBits().

Specified by:

getBitStream in interface ASN1BitStringParser

Returns:

an InputStream with its source as the BIT STRING content.

Throws:

java.io.IOException

getOctetStream

public java.io.InputStream getOctetStream()
                                   throws java.io.IOException

Description copied from interface: ASN1BitStringParser

Return an InputStream representing the contents of the BIT STRING, where the content is expected to be octet-aligned (this will be automatically checked during parsing).

Specified by:

getOctetStream in interface ASN1BitStringParser

Returns:

an InputStream with its source as the BIT STRING content.

Throws:

java.io.IOException

getPadBits

public int getPadBits()

Description copied from interface: ASN1BitStringParser

Return the number of pad bits, if any, in the final byte, if any, read from ASN1BitStringParser.getBitStream(). This number is in the range zero to seven. That number of the least significant bits of the final byte, if any, are not part of the contents and should be ignored. NOTE: Must be called AFTER the stream has been fully processed. (Does not need to be called if ASN1BitStringParser.getOctetStream() was used instead of ASN1BitStringParser.getBitStream()).

Specified by:

getPadBits in interface ASN1BitStringParser

Returns:

the number of pad bits. In the range zero to seven.

getLoadedObject

public ASN1Primitive getLoadedObject()
                              throws java.io.IOException

Description copied from interface: InMemoryRepresentable

Get the in-memory representation of the ASN.1 object.

Specified by:

getLoadedObject in interface InMemoryRepresentable

Returns:

an ASN1Primitive representing the loaded object.

Throws:

java.io.IOException - for bad input data.

toASN1Primitive

public ASN1Primitive toASN1Primitive()

Description copied from interface: ASN1Encodable

Return an object, possibly constructed, of ASN.1 primitives

Specified by:

toASN1Primitive in interface ASN1Encodable

Returns:

an ASN.1 primitive.
