public interface DelayedMulticastRequestDecoder
extends MulticastRequestDecoder

Interface implemented by classes which decode multicast request data and additionally support delayed constraint checking.

Method Summary
 MulticastRequest decodeMulticastRequest(ByteBuffer buf, InvocationConstraints constraints, ClientSubjectChecker checker, boolean delayConstraintCheck)
          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, with constraint checking optionally delayed.

Method Detail

decodeMulticastRequest

MulticastRequest decodeMulticastRequest(ByteBuffer buf,
                                        InvocationConstraints constraints,
                                        ClientSubjectChecker checker,
                                        boolean delayConstraintCheck)
                                        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, with constraint checking optionally delayed. null constraints are considered equivalent to empty constraints. Constraint checking may be delayed using the delayConstraintCheck flag.

If the delayConstraintCheck flag is true, the method behaves as follows:

If delayConstraintCheck is false, all the specified constraints are checked before this method returns.

Parameters:
buf - a buffer containing the packet data to decode. The contents of buf may be used on subsequent invocations of the returned MulticastRequest instance's checkConstraints method. The caller must ensure that the contents of buf are not modified before invocation of the checkConstraints method. Additionally, 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
delayConstraintCheck - flag to control delayed constraint checking
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
