Package org.apache.thrift
Class TMultiplexedProcessor
- java.lang.Object
-
- org.apache.thrift.TMultiplexedProcessor
-
- All Implemented Interfaces:
TProcessor
public class TMultiplexedProcessor extends java.lang.Object implements TProcessor
TMultiplexedProcessor
is aTProcessor
allowing a singleTServer
to provide multiple services.To do so, you instantiate the processor and then register additional processors with it, as shown in the following example:
TMultiplexedProcessor processor = new TMultiplexedProcessor(); processor.registerProcessor( "Calculator", new Calculator.Processor(new CalculatorHandler())); processor.registerProcessor( "WeatherReport", new WeatherReport.Processor(new WeatherReportHandler())); TServerTransport t = new TServerSocket(9090); TSimpleServer server = new TSimpleServer(processor, t); server.serve();

Method Summary
All Methods Instance Methods Concrete Methods Modifier and Type Method Description boolean
process(TProtocol iprot, TProtocol oprot)
This implementation ofprocess
performs the following steps: Read the beginning of the message. Extract the service name from the message. Using the service name to locate the appropriate processor. Dispatch to the processor, with a decorated instance of TProtocol that allows readMessageBegin() to return the original TMessage.void
registerProcessor(java.lang.String serviceName, TProcessor processor)
'Register' a service with thisTMultiplexedProcessor

Method Detail
-
registerProcessor
public void registerProcessor(java.lang.String serviceName, TProcessor processor)
'Register' a service with thisTMultiplexedProcessor
. This allows us to broker requests to individual services by using the service name to select them at request time.- Parameters:
serviceName
- Name of a service, has to be identical to the name declared in the Thrift IDL, e.g. "WeatherReport".processor
- Implementation of a service, ususally referred to as "handlers", e.g. WeatherReportHandler implementing WeatherReport.Iface.
-
process
public boolean process(TProtocol iprot, TProtocol oprot) throws TException
This implementation ofprocess
performs the following steps:- Read the beginning of the message.
- Extract the service name from the message.
- Using the service name to locate the appropriate processor.
- Dispatch to the processor, with a decorated instance of TProtocol that allows readMessageBegin() to return the original TMessage.
- Specified by:
process
in interfaceTProcessor
- Throws:
TException
- If the message type is not CALL or ONEWAY, if the service name was not found in the message, or if the service name was not found in the service map. You calledregisterProcessor
during initialization, right? :)
