Interface TransportManager

public interface TransportManager

A singleton object that provides the main point of centralization for managing different transport providers, endpoint registration, control, processing of inbound and outbound messages, etc

Field Summary

static String	TRANSPORT_ERROR_GENERIC String representation of generic error code
static String	TRANSPORT_RESOURCE_NAME internal name used by monitoring subsystem
static int	TRANSPORT_STATUS_ERROR transport specific status code that indicates generic error
static int	TRANSPORT_STATUS_OK transport specific status code that indicates success

Method Summary

Transformer	getTransformer()
void	receiveMessage(InboundTransportMessageContext ctx, TransportOptions options) Processes an inbound message: the caller is the transport endpoint implementation, and transport manager passes the message context down to the router manager, which sends the incoming message down the request pipeline.
void	registerProvider(TransportProvider p, Transformer t) Registers a new provider with the transport manager.

Method Detail

registerProvider

void registerProvider(TransportProvider p,
                      Transformer t)
                      throws TransportException

Registers a new provider with the transport manager. Typically called by the transport provider’s ApplicationLifeCycleListener postStart() method. Optional transformer argument allows the transport provider or ALSB runtime to perform custom transformations from custom Source-derived classes to one or more of standard results.

Parameters:

p - new tramsport provider to be registered with ALSB subsystem

t - transformer for those provider that support custom sources and tranbsformations. Maybe null.

Throws:

TransportException

receiveMessage

void receiveMessage(InboundTransportMessageContext ctx,
                    TransportOptions options)
                    throws TransportException

Processes an inbound message: the caller is the transport endpoint implementation, and transport manager passes the message context down to the router manager, which sends the incoming message down the request pipeline. The TransportManager will eventually put a response (if any) into the InboundTransportMessageContext and signal its readiness to be sent by calling InboundTransportMessageContext.close().

Parameters:

ctx - message context created by transport provider

options - provider-supplied directives on processing the message, e.g. desired quality of service

Throws:

TransportException

getTransformer

Transformer getTransformer()

Returns:

the “uber”-Transformer, i.e. the union of all available transformers, including custom ones
