ACE_Future_Rep<T>
An ACE_Future_Rep<T> object encapsules a pointer to an object of class T which is the result of an asynchronous method invocation. It is pointed to by ACE_Future<T> object[s] and only accessible through them.

Decreases the rep's reference count and deletes rep if there are no more references to rep. Then assigns new_rep to rep.
Precondition (rep != 0 && new_rep != 0)
|
private |
Attaches the specified observer to a subject (i.e., the ACE_Future_Rep). The update method of the specified subject will be invoked with a copy of the written-to ACE_Future as input when the result gets set.
Returns 0 if the observer is successfully attached, 1 if the observer is already attached, and -1 if failures occur.
|
staticprivate |
Increase the reference count and return argument. Uses the attribute "value_ready_mutex_" to synchronize reference count updating.
Precondition (rep != 0).
|
staticprivate |
Create a ACE_Future_Rep<T> and initialize the reference count.
|
private |
Detaches the specified observer from a subject (i.e., the ACE_Future_Rep). The update method of the specified subject will not be invoked when the ACE_Future_Reps result gets set. Returns 1 if the specified observer was actually attached to the subject prior to this call and 0 if was not.
Returns 0 if the observer was successfully detached, and -1 if the observer was not attached in the first place.

Decreases the reference count and deletes rep if there are no more references to rep.

Dump the state of an object.

Wait up to tv time to get the value. Note that tv must be specified in absolute time rather than relative time.
|
staticprivate |
Allocate a new ACE_Future_Rep<T> instance, returning NULL if it cannot be created.
|
private |
Type conversion. will block forever until the result is available. Note that this method is going away in a subsequent release since it doesn't distinguish between failure results and success results (exceptions should be used, but they aren't portable...). The <get> method should be used instead since it separates the error value from the result, and also permits timeouts.
|
private |
Is result available?
|
private |
Set the result value. The specified caller represents the future that invoked this <set> method, which is used to notify the list of future observers. Returns 0 for success, -1 on error. This function only has an effect the first time it is called for the object. Subsequent calls return 0 (success) but have no effect.
