VSTaskManager

public VSTaskManager(VSPrefs prefs,
                     VSSimulatorVisualization simulatorVisualization)

Instantiates a new task manager object.

Parameters:

prefs - the simulator's default prefs

simulatorVisualization - the simulator canvas

Method Detail

runTasks

public void runTasks(long step,
                     long offset,
                     long lastGlobalTime)

Run tasks. This method gets called by the simulator canvas repeatedly. Almost all simulator actions take place in this method.

Parameters:

step - the step

offset - the offset

lastGlobalTime - the last global time

reset

public void reset()

Resets the task manager.

addTask

public void addTask(VSTask task)

Adds a task.

Parameters:

task - the task to add

addTask

public void addTask(VSTask task,
                    boolean isProgrammed)

Adds a task.

Parameters:

task - the task to add

isProgrammed - true, if the task is programmed

removeTask

public boolean removeTask(VSTask task)

Removes a task.

Parameters:

task - the task to remove

Returns:

true, if the task has been removed with success

removeAllTasks

public void removeAllTasks(java.util.ArrayList<VSTask> tasks)

Removes several tasks.

Parameters:

tasks - the tasks to remove

removeTasksOf

public void removeTasksOf(VSInternalProcess process)

Removes the tasks of the specified process.

Parameters:

process - the process to remove the tasks of

getLocalTasks

public java.util.ArrayList<VSTask> getLocalTasks()

Gets the local timed tasks.

Returns:

the local timed tasks

getGlobalTasks

Returns:

the global timed tasks

getProcessLocalTasks

public java.util.ArrayList<VSTask> getProcessLocalTasks(VSInternalProcess process)

Gets the local timed tasks of a specific process.

Parameters:

process - the process to get the local timed tasks of

Returns:

the local tasks of the specified process

getProcessGlobalTasks

public java.util.ArrayList<VSTask> getProcessGlobalTasks(VSInternalProcess process)

Gets the global timed tasks of a specific process.

Parameters:
