Interface Threadable<T,U>

Type Parameters:

T - This type parameter specifies the type of data object which may be passed into the threadable task.

U - This type parameter specifies the type of data object which will be passed back by the threadable task on completion.

public interface Threadable<T,U>

Defines the interface to a threadable task object. Threadable task objects can be submitted to the reactor in order to run in a separate thread. This is useful for executing code which contains blocking calls within the Reaction framework. On submitting a threadable task object to the reactor using the runThread method on the Reactor interface, an object implementing the Deferred interface is returned which will be used to forward the results generated by the run method on completion.

Method Summary

U	run(T data) Runs a threadable task in the context of a new thread.

Method Detail

run

U run(T data)
      throws java.lang.Exception

Runs a threadable task in the context of a new thread. On submitting an object implementing this interface for threaded execution, this method will be called by the reactor in the context of a new thread. On normal completion it will return a data object which will be passed as the callback parameter to the deferred callback chain. Alternatively, if an exception is thrown this will be passed as the errback parameter to the error callback chain.

Parameters:

data - This is the input data object which is provided when submitting the threadable task object to the reactor.

Returns:

Returns an output data object which will be passed to the deferred callback chain as the onCallback parameter.

Throws:

java.lang.Exception - On an exception, the exception object is passed to the deferred error callback chain as the onErrback parameter.
