◆ execute()

executes the job synchronously

Argumentsare arguments for executing the job. Their semantics is completely implementation dependent. Usually, a concrete implementation of a job specifies in its service descriptions which parameters are allowed (or expected). This values are persistent by the configuration of theJobExecutor which use this synchronous job. It's possible to write it back by use special protocol in return value.
the result of the job. The concrete semantics is service-dependent. But it should be possible to
  • deregister the job
  • let him registered although execution was successful(!)
  • make some job specific data persistent inside the job configuration which is provided by the executor.
com::sun::star::lang::IllegalArgumentExceptionif some of given arguments doesn't fill out the service specification or was corrupt so the service couldn't work correctly
com::sun::star::uno::Exceptionto notify the executor about failed operation; otherwise the return value indicates a successful finishing.
