CrossSection

public CrossSection()

Method Details

updateSource

public abstract void updateSource()

Description copied from interface: IUpdatableSource

Force the source to update its currently cached data.

Specified by:

updateSource in interface IUpdatableSource

onEvent

public void onEvent(Enum<?> type)

ISimEventListener callback function. It supports only jas.engine.Sim.EVENT_UPDATE event.

Specified by:

onEvent in interface EventListener

Throws:

UnsupportedOperationException - If actionType is not supported.

getSourceArray

public Object[] getSourceArray()

Specified by:

getSourceArray in interface ISourceObjectArray

getFilter

public ICollectionFilter getFilter()

Returns:

setFilter

public void setFilter(ICollectionFilter filter)

Parameters:

filter -

isCheckingTime

public boolean isCheckingTime()

Return the current status of the time checker. A time checker avoid the object to update more than one time per simulation step. The default value is enabled (true).

Returns:

True if the computer is currently checking time before update cached data, false if disabled.

setCheckingTime

public void setCheckingTime(boolean b)

Set the current status of the time checker. A time checker avoid the object to update more than one time per simulation step. The default value is enabled (true).

Parameters:

b - True if the computer is currently checking time before update cached data, false if disabled.
