Examples of org.apache.shiro.subject.Subject.execute()

org.apache.shiro.subject.Subject.execute()
Associates the specified {@code Callable} with this {@code Subject} instance and then executes it on thecurrently running thread. If you want to execute the {@code Callable} on a different thread, it is better touse the {@link #associateWith(Callable)} method instead. @param callable the Callable to associate with this subject and then execute. @param < V> the type of return value the {@code Callable} will return @return the resulting object returned by the {@code Callable}'s execution. @throws ExecutionException if the {@code Callable}'s {@link Callable#call call} method throws an exception. @since 1.0
