Description copied from interface: AmqpLink

Handles an incoming flow control.

Throws:

Exception

getConfiguredReceiverCredit

public int getConfiguredReceiverCredit()

Returns the amount of receiver credit that has been configured for this AMQP transport. If no value was configured on the TransportConnector URI then a sensible default is used.

Returns:

the configured receiver credit to grant.

flow

public void flow(int credits)

Provide the receiver endpoint with the given amount of credits.

Parameters:

credits - the credit value to pass on to the wrapped Receiver.

commit
