public interface ExecutableObject

An ExecutableObject provides a high-level abstraction for elements that can be executed on the Grid. It can be specialized as a Grid Taskor a TaskGraph. Every ExecutableObject in the abstractions framework has a unique Identityand an execution Status.

Field Summary

static int	TASK Represents a Tasktype ExecutableObject
static int	TASKGRAPH Represents a TaskGraphtype ExecutableObject

Method Summary

void	addStatusListener(StatusListener listener) Adds a listener to receive status events when the status of an ExecutableObject is changed.
Identity	getIdentity() Returns the unique Identity assigned to this ExecutableObject.
String	getName() Returns the user-friendly name assigned to this ExecutableObject.
int	getObjectType() Returns the type of this ExecutableObject.
Status	getStatus() Returns the current Status of this ExecutableObject.
void	removeStatusListener(StatusListener listener) Removes the status listener from the list of active listeners.
void	setIdentity(Identity id) Sets a unique Identity for this ExecutableObject.
void	setName(String name) Sets the name of this ExecutableObject.
void	setStatus(int status) Sets the current status of this ExecutableObject.
void	setStatus(Status status) Sets the current Status of this ExecutableObject.
