public interface Execution

An execution represents the state and lifecycle for a particular command execution. The methods provided on this interface define standard lifecycle methods. When execution completes, the close() will be called. If execution must be aborted, due to user or administrator action, the cancel() will be called.

Method Summary

Modifier and Type	Method and Description
void	cancel() Cancels the execution abnormally.
void	close() Terminates the execution normally.
void	execute() Execute the associated command.

Method Detail

close

void close()

Terminates the execution normally.

cancel

void cancel()
     throws TranslatorException

Cancels the execution abnormally. This will happen via a different thread from the one performing the execution, so should be expected to happen in a multi-threaded scenario.

Throws:

TranslatorException

execute

void execute()
      throws TranslatorException

Execute the associated command. Results will be retrieved through a specific sub-interface call.

Throws:

TranslatorException
