Constructor Detail

JavaTaskExecutorImpl

public JavaTaskExecutorImpl()

Method Detail

launch

public void launch()
            throws ExecutionComponentStateException

Description copied from interface: IExecutor

Launches the executable on this ISession's node

Specified by:

launch in interface IExecutor

Throws:

ExecutionComponentStateException

See Also:

IExecutor.launch()

kill

public void kill()
          throws ExecutionComponentStateException

Description copied from interface: IExecutor

Kills this process if it is active.

Specified by:

kill in interface IExecutor

Throws:

ExecutionComponentStateException

See Also:

IExecutor.kill()

setExecutableObject

public void setExecutableObject(IExecutableObject theExecutableObject)
                         throws ExecutionComponentStateException

Description copied from interface: IExecutor

Set the executable object. The executable object contains all information necessary to execute within the parent execution environment

Specified by:

setExecutableObject in interface IExecutor

Parameters:

theExecutableObject - An IExecutableObject instance which describes the executable in a manner understood by this IExecutor.

Throws:

ExecutionComponentStateException - If the IExecutor is not in a valid state to accept an IExecutableObject.

See Also:

IExecutor.setExecutableObject(org.eclipse.hyades.execution.core.IExecutableObject)

getExecutableObject

public IExecutableObject getExecutableObject()

Specified by:

getExecutableObject in interface IExecutor

See Also:

IExecutor.getExecutableObject()

getProcessConsole

public IProcessConsole getProcessConsole()
                                  throws ExecutionComponentStateException

Description copied from interface: IExecutor

Return the process console of the current executor

Specified by:

getProcessConsole in interface IExecutor

Returns:

IProcessConsole

Throws:

ExecutionComponentStateException

See Also:

IExecutor.getProcessConsole()

getCompatibleExecutableObject

public IExecutableObject getCompatibleExecutableObject(java.lang.String classname)
                                                throws java.lang.ClassNotFoundException

Description copied from interface: IExecutor

Returns an empty instance of an IExecutableObject that is compatible with this IExecutor.

Issue: Do we want this to be the ExecutableObject (thus replacing the setExecutableObject() method), and if so, how do we know when to pass the object across the wire (since the IExecutor doing the real work won't be the same instance of IExecutor that contains this IExecutableObject.)

Specified by:

getCompatibleExecutableObject in interface IExecutor

Returns:

an empty instance of a compatible IExecutableObject.

Throws:

java.lang.ClassNotFoundException

See Also:

org.eclipse.hyades.execution.core.IExecutor#getCompatibleExecutableObject()

checkConfiguration

protected void checkConfiguration()
                           throws ExecutionComponentStateException

Insure this executor has been been appropriately configured for the requested operation.

Throws:

ExecutionComponentStateException

supportsControlEvent

public boolean supportsControlEvent(java.lang.String controlEvent)

Description copied from interface: IExecutor

Returns a boolean specifying whether the control event specified is supported.

Specified by:

supportsControlEvent in interface IExecutor

Parameters:

controlEvent - Contol Event in question.

Returns:

Specifies whether the control event is supported.

performControlEvent

public java.lang.String performControlEvent(java.lang.String controlEvent,
                                            java.lang.String[] params)

Description copied from interface: IExecutor

Performs the control event specified.

Specified by:

performControlEvent in interface IExecutor

Parameters:

controlEvent - Contol Event to perform.

Returns:

Error Message if error occurred. Otherwise null.
