Method Detail

call

public CallStatus call()
                throws Exception

Description copied from class: Operation

Call the operation and returns the CallStatus. An Operation should either implement call or run; not both. If run is implemented, then the system remains backwards compatible to prevent making massive code changes while adding this feature. In the future all Operation.run() methods will be replaced by call methods. The call method looks very much like the Operation.run() method and it is very close to Runnable.run() and Callable.call(). The main difference between a run and call, is that the returned CallStatus from the call can tell something about the actual execution. For example it could tell that some waiting is required in case of a BlockingOperation. Or that the actual execution work is offloaded to some executor in case of an Offloadable EntryOperation. In the future new types of CallStatus are expected to be added, e.g. for interleaving. In the future it is very likely that for regular Operation that want to return a concrete response, the actual response can be returned directly. In this case we'll change the return type to Object to prevent forcing the response to be wrapped in a CallStatus.DONE_RESPONSE monad since that would force additional litter to be created.

Overrides:

call in class Operation

Returns:

the CallStatus.

Throws:

Exception - if something failed while executing 'call'.
