+--java.de.TimeSlice.TaskManager
- public class TaskManager
- extends java.lang.Object
- implements ControlPanelListener, java.de.TimeSlice.TimerListener
class
TaskManager
is one of the
main processing classes. It manages the
existing tasks and the active task. It is
called to update periodically by the Timer
by implementing TimerListener
Changes due to user-interaction with the GUI
are notified trough ControlPanelListener
Constructor Summary |
TaskManager()
some constructors are really boring |
Method Summary |
void |
activateTask(boolean active,
java.lang.String TaskName)
sets the stae of the Task named TaskName
to active and has to check and adjust
ActiveTask |
void |
addTask(Task t)
add Task t to Tasks if it fulfills all
restrictions like uniqueness of the Taskname and
ranges of data |
void |
deleteTask(java.lang.String TaskName)
since the timer accesses ActiveTask periodically
one has to escape access conflicts by a synchronized access |
void |
editTask(java.lang.String OldName,
Task t)
nearly the same like addTask() but the existing
Task is preserved and the properties are set to the new values |
Task |
getActiveTask()
|
Task |
getTask(java.lang.String TaskName)
|
void |
setActiveTask(Task Value)
|
void |
setTask(java.lang.String OldName,
Task Value)
|
void |
updateActiveTask(long delta)
part of the interface TimerListener
called periodically. |
void |
updateDayChange(long now)
under construction !! |

TaskManager
public TaskManager()
- some constructors are really boring
addTask
public void addTask(Task t)
throws java.de.TimeSlice.TaskNameAlreadyExist,
java.security.InvalidParameterException
- add Task t to
Tasks
if it fulfills all
restrictions like uniqueness of the Taskname and
ranges of data
- Specified by:
- addTask in interface ControlPanelListener
- Parameters:
t
- Task to add- Throws:
- java.de.TimeSlice.TaskNameAlreadyExist -
- java.security.InvalidParameterException -
editTask
public void editTask(java.lang.String OldName,
Task t)
throws java.de.TimeSlice.TaskNameAlreadyExist,
java.security.InvalidParameterException
- nearly the same like
addTask()
but the existing
Task is preserved and the properties are set to the new values
- Specified by:
- editTask in interface ControlPanelListener
- Parameters:
OldName
- t
- - Throws:
- java.de.TimeSlice.TaskNameAlreadyExist -
- java.security.InvalidParameterException -
deleteTask
public void deleteTask(java.lang.String TaskName)
- since the timer accesses
ActiveTask
periodically
one has to escape access conflicts by a synchronized access
- Specified by:
- deleteTask in interface ControlPanelListener
- Parameters:
TaskName
-
activateTask
public void activateTask(boolean active,
java.lang.String TaskName)
- sets the stae of the Task named
TaskName
to active
and has to check and adjust
ActiveTask
- Specified by:
- activateTask in interface ControlPanelListener
- Parameters:
active
- TaskName
-
getActiveTask
public Task getActiveTask()
setActiveTask
public void setActiveTask(Task Value)
getTask
public Task getTask(java.lang.String TaskName)
setTask
public void setTask(java.lang.String OldName,
Task Value)
updateActiveTask
public void updateActiveTask(long delta)
- part of the interface
TimerListener
called periodically. Updates the Restdauer
of the currently active Task (only one Task can be
active a time). Like explained in the preceeding this
access has to be synchronized
- Specified by:
- updateActiveTask in interface java.de.TimeSlice.TimerListener
- Parameters:
delta
-
updateDayChange
public void updateDayChange(long now)
- under construction !!
- Specified by:
- updateDayChange in interface java.de.TimeSlice.TimerListener
- Parameters:
now
