    All Methods Instance Methods Abstract Methods
    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
