      • execute

        <R> Optional<R> execute​(Supplier<R> executeTask)
        Deprecated, for removal: This API element is subject to removal in a future version.
        Executes the specified task, but only if the service was not already closed. If service is already closed, the task is not run. If executed, the specified task must return a non-null value, to be distinguishable from a non-execution.
        Parameters:
        executeTask - a task to execute
        Returns:
        an optional value that is present only if the specified task was run.

        <R,​E extends Exception> Optional<R> execute​(org.wildfly.common.function.ExceptionSupplier<R,​E> executeTask)
                                           throws E extends Exception
        Deprecated, for removal: This API element is subject to removal in a future version.
        Executes the specified task, but only if the service was not already closed. If service is already closed, the task is not run. If executed, the specified task must return a non-null value, to be distinguishable from a non-execution.
        Parameters:
        executeTask - a task to execute
        Returns:
        an optional value that is present only if the specified task was run.
        Throws:

        Deprecated, for removal: This API element is subject to removal in a future version.
        Closes the service, executing the specified task, first waiting for any concurrent executions to complete. The specified task will only execute once, irrespective on subsequent close(Runnable) invocations.
        Parameters:
        closeTask - a task which closes the service
