Method Detail

addProcessor

void addProcessor(MessageProcessor<? extends Message<? extends MessageResponse>,? extends MessageResponse> processor)

Adds processor to the message processor registry.

Parameters:

processor - Message processor to add to the message processor registry.

addProcessors

void addProcessors(List<? extends MessageProcessor<? extends Message<? extends MessageResponse>,? extends MessageResponse>> processors)

Adds processors to the message processor registry.

Parameters:

processors - List of message processors to add to the message processor registry.

getProcessorFor

MessageProcessor<? extends Message<? extends MessageResponse>,? extends MessageResponse> getProcessorFor(String messageType)

Retrieves a concrete MessageProcessor for the type of the message. If not found, returns null.

Parameters:

messageType - Message type identifier that is unique system-wide.

Returns:

An instance of a concrete implementation of MessageProcessor based on the messageType. If no processor is found for the message type, returns null.

removeProcessor

void removeProcessor(String messageType)

Removes message processor which is identified by the messageType from the message processor registry.

Parameters:

messageType - Message type identifier that is unique system-wide.

getProcessors

List<MessageProcessor<? extends Message<? extends MessageResponse>,? extends MessageResponse>> getProcessors()

Retrieve all message processors successfully registered in the message processor registry.

Returns:

List of successfully discovered and registered message processors. If none are registered, returns an empty list.
