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

void	close() Terminates the execution normally.
void	execute() Execute the associated command.

Method Detail

             throws TranslatorException

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