Interface ILcdSimulatorModel

All Superinterfaces:

ILcdPropertyChangeSource

All Known Implementing Classes:

ALcdSimulatorModel, ALcdTimeIndexedSimulatorModel, TLcdSimulatorModelList, TLcdTimeFilteredSimulatorModel

public interface ILcdSimulatorModel
extends ILcdPropertyChangeSource

An ILcdSimulatorModel defines the simulated data to be displayed by a TLcdSimulator in real or fast time onto different ILcdGXYViews. Its main responsibility is to provide its TLcdSimulator with the ILcdModels holding the simulated domain data, and to put these data in the state corresponding to a given time of the simulation (setDate).

Threading considerations

Simulator models should always be accessed on the AWT Event Dispatch Thread.

Method Summary

Modifier and Type	Method	Description
Date	getBeginDate()	Returns the begin Date of the simulation.
Date	getDate()	Gets the Date corresponding to the current state of the domain objects (tracks) this ILcdSimulatorModel contains.
Date	getEndDate()	Returns the end Date of the simulation.
ILcdModel[]	getTrackModels()	Returns the array of ILcdModels holding the simulated domain data.
void	setDate(Date aDate)	Asks this ILcdSimulatorModel to update the domain objects (tracks) of the simulation it contains, in order to be in the state in which they were or should be at the given Date.

Method Details

getTrackModels

ILcdModel[] getTrackModels()

Returns the array of ILcdModels holding the simulated domain data. The state of the domain objects in these models is updated when setDate is called.

A property change event must be fired whenever the return value of this method changes.

Returns:

The array of ILcdModels holding the simulated domain data. This must not be null.

See Also:

• setDate(java.util.Date)

setDate

void setDate(Date aDate)

Asks this ILcdSimulatorModel to update the domain objects (tracks) of the simulation it contains, in order to be in the state in which they were or should be at the given Date. This state might include location, feature values, etc.

The TLcdSimulator always calls this method on the AWT Event Dispatch Thread

Implementations of this method should respect the threading rules of LuciadLightspeed. Specifically, implementations should take a write lock on the track models they update when creating a multithreaded application.

Parameters:

aDate - The Date to update to. This is never null.

• getTrackModels()
• getDate()
• TLcdLockUtil.writeLock(Object)

getDate

Date getDate()

Gets the Date corresponding to the current state of the domain objects (tracks) this ILcdSimulatorModel contains.

Returns:

The Date of the current state.

See Also:

• setDate(Date)

getBeginDate

Date getBeginDate()

Returns the begin Date of the simulation.

A property change event must be fired whenever the return value of this method changes.

Returns:

The begin Date of the simulation. This must not be null.

getEndDate

Date getEndDate()

Returns the end Date of the simulation.

A property change event must be fired whenever the return value of this method changes.

Returns:

The end Date of the simulation. This must not be null.
