Method Summary
 MulticastRequest decodeMulticastRequest(ByteBuffer buf, InvocationConstraints constraints, ClientSubjectChecker checker)
          Decodes the multicast request data contained in the given buffer in a manner that satisfies the specified absolute constraints and client subject checker (if any), returning a MulticastRequest instance that contains the decoded data.

Method Detail

decodeMulticastRequest

MulticastRequest decodeMulticastRequest(ByteBuffer buf,
                                        InvocationConstraints constraints,
                                        ClientSubjectChecker checker)
                                        throws IOException
Decodes the multicast request data contained in the given buffer in a manner that satisfies the specified absolute constraints and client subject checker (if any), returning a MulticastRequest instance that contains the decoded data. null constraints are considered equivalent to empty constraints. All the specified constraints are checked before this method returns.

Parameters:
buf - a buffer containing the packet data to decode. The multicast request data must begin at position zero of buf.
constraints - the constraints to apply when decoding the data, or null
checker - the object to use to check the client subject, or null
Returns:
the decoded multicast request data
Throws:
IOException - if an error occurs in interpreting the data
UnsupportedConstraintException - if unable to satisfy the specified constraints
SecurityException - if the given constraints cannot be satisfied due to insufficient caller permissions, or if the client subject check fails
NullPointerException - if buf is null
