isHeaderValid

public boolean isHeaderValid(AmqpHeader header)

Given an AMQP header validate that the AMQP magic is present and if so that the version and protocol values align with what we support.

Parameters:

header - the header instance received from the client.

Returns:

true if the header is valid against the current WireFormat.

getMinimallySupportedHeader

public AmqpHeader getMinimallySupportedHeader()

Returns an AMQP Header object that represents the minimally protocol versions supported by this transport. A client that attempts to connect with an AMQP version that doesn't at least meat this value will receive this prior to the connection being closed.

Returns:

the minimal AMQP version needed from the client.
