Modifier and Type	Method and Description
<T> T	invoke(Class<T> proxyType, Invokable<T> invocable) As with invoke(org.apache.tapestry5.ioc.Invokable), but the result is wrapped inside a thunk.
<T> Future<T>	invoke(Invokable<T> invocable) Submits the invocable object to be executed in a pooled thread.

Method Detail

invoke

<T> Future<T> invoke(Invokable<T> invocable)

Submits the invocable object to be executed in a pooled thread. Returns a Future object representing the eventual result of the invocable's operation. The actual operation will be wrapped such that PerthreadManager.cleanup() is invoked after the operation completes.

Type Parameters:

T -

Parameters:

invocable - to execute in a thread

Returns:

Future result of that invocation

invoke

<T> T invoke(Class<T> proxyType,
             Invokable<T> invocable)

As with invoke(org.apache.tapestry5.ioc.Invokable), but the result is wrapped inside a thunk. Invoking methods on the thunk will block until the value is available.

Type Parameters:

T -

Parameters:

proxyType - return type, used to create the thunk

invocable - object that will eventually execute and return a value

Returns:

the thunk
