Class TupleTreeDecoder

java.lang.Object
  org.apache.asn1.ber.TupleTreeDecoder

All Implemented Interfaces:

org.apache.asn1.codec.stateful.StatefulDecoder

public class TupleTreeDecoder

extends java.lang.Object

implements org.apache.asn1.codec.stateful.StatefulDecoder

Builds a TLV tree from the TLV stream emitted from the decoder. The decoded objects delivered to this StatefulDecoder's DecoderCallback are DefaultMutableTupleNodes.

Constructor Detail

TupleTreeDecoder

public TupleTreeDecoder()

Creates a simple BER byte stream to TLV Tuple tree decoder.

Method Detail

handleTuple

private void handleTuple(Tuple t)

Handles a tuple recieved from the underlying BER byte stream decoder.

Parameters:

t - the tuple to handle

decode

public void decode(java.lang.Object encoded)
            throws org.apache.asn1.codec.DecoderException

Specified by:

decode in interface org.apache.asn1.codec.stateful.StatefulDecoder

Throws:

org.apache.asn1.codec.DecoderException

treeDecode

public static TupleNode treeDecode(java.nio.ByteBuffer buf)
                            throws org.apache.asn1.codec.DecoderException

Decodes a BER byte buffer into a tree of TLV tuples.

Parameters:

buf - the buffer to decode

Returns:

the TLV tuple node with children if applicable

Throws:

org.apache.asn1.codec.DecoderException - if there is a problem decoding the data

java.util.NoSuchElementException - if there is not enough data to properly decode a complete TLV tree
