Method Detail

getName

String getName()

Unique name of the resource instance.

Returns:

The unique name of the resource instance.

getRunningProcess

IRunningProcess getRunningProcess()

Returns:

Returns the process currently executing on the resource.

processAssigned

boolean processAssigned()

Returns:

True, if there is process executing on this resource instance, false otherwise.

assign

void assign(IRunningProcess process)

Assigns a new process to this instance. Note that the resource has to be idle to do so.

Parameters:

process - Process to execute on the resource instance.

release

Parameters:

time -

b -

cancelSchedulingEvent
