Method Detail

decodeMulticastAnnouncement

MulticastAnnouncement decodeMulticastAnnouncement(ByteBuffer buf,
                                                  InvocationConstraints constraints)
                                                  throws IOException
Decodes the multicast announcement data contained in the given buffer in a manner that satisfies the specified absolute constraints, returning a MulticastAnnouncement 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 announcement data must begin at position zero of buf.
constraints - the constraints to apply when decoding the data, or null
Returns:
the decoded multicast announcement 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
NullPointerException - if buf is null
