Class ParallelDispatchProxy<I>

java.lang.Object
  org.lsst.ccs.utilities.dispatch.ParallelDispatchProxy<I>

public class ParallelDispatchProxy<I>
extends Object

Instances of this class creates a dynamic proxy that parallely dispatches method call to registered agents implementing an interface type.

beware : if the implemented interface is itself a parameterized type no type control is exercised on these type parameters.

Field Summary

protected CopyOnWriteArrayList<Object>	list
protected ExecutorService	loop
protected I	proxy

Constructor Summary

ParallelDispatchProxy(Class<I> interfaceType)
prepares a generator able to deliver a Proxy object able to dispatch method calls to registered agents.

ParallelDispatchProxy(Class<I> interfaceType, boolean singleThread)
Same as ParallelDispatchProxy but specification of a single Thread dispatch can be added.

ParallelDispatchProxy(Class<I> interfaceType, ClassLoader loader)
Same as previous but with a specified ClassLoader

ParallelDispatchProxy(Class<I> interfaceType, ClassLoader loader, boolean singleThread)

Method Summary

<T extends I> void	addExecutant(T executant) Registers a code ready to receive "synchronous" commands
I	getProxy() to be called once to get a dynamically generated proxy that will forward calls to registered agents.
<T extends I> void	removeExecutant(T executant) Remove the code from the listeners list

Constructor Detail

ParallelDispatchProxy

public ParallelDispatchProxy(Class<I> interfaceType)

prepares a generator able to deliver a Proxy object able to dispatch method calls to registered agents. The methods of the interface will necessarily be of procedural nature (the return values will be dumped)

Parameters:

interfaceType -

ParallelDispatchProxy

public ParallelDispatchProxy(Class<I> interfaceType,
                             boolean singleThread)

Same as ParallelDispatchProxy but specification of a single Thread dispatch can be added.

Parameters:

interfaceType -

singleThread -

ParallelDispatchProxy

public ParallelDispatchProxy(Class<I> interfaceType,
                             ClassLoader loader)

Same as previous but with a specified ClassLoader

Parameters:

interfaceType -

loader -

ParallelDispatchProxy

public ParallelDispatchProxy(Class<I> interfaceType,
                             ClassLoader loader,
                             boolean singleThread)

Method Detail

addExecutant

public <T extends I> void addExecutant(T executant)

Registers a code ready to receive "synchronous" commands

Parameters:

executant - (should implement the interface)

removeExecutant

public <T extends I> void removeExecutant(T executant)

Remove the code from the listeners list

Parameters:

executant -

getProxy

public I getProxy()

to be called once to get a dynamically generated proxy that will forward calls to registered agents.

Returns:
