Constructor Detail

BasicOrbitViewLimits

public BasicOrbitViewLimits()

Creates a new BasicOrbitViewLimits with default limits.

Method Detail

getCenterElevationLimits

public double[] getCenterElevationLimits()

Returns the minimum and maximum values for the orbit view center elevation.

Specified by:

getCenterElevationLimits in interface OrbitViewLimits

Returns:

Minimum and maximum allowable values for center elevation.

getCenterLocationLimits

public Sector getCenterLocationLimits()

Returns the Sector which limits the orbit view center latitude and longitude.

Specified by:

getCenterLocationLimits in interface OrbitViewLimits

Returns:

Sector which limits the center latitude and longitude.

getRestorableState

public void getRestorableState(RestorableSupport rs,
                               RestorableSupport.StateObject context)

Specified by:

getRestorableState in interface ViewPropertyLimits

Overrides:

getRestorableState in class BasicViewPropertyLimits

getZoomLimits

public double[] getZoomLimits()

Returns the minimum and maximum values for the orbit view zoom property.

Specified by:

getZoomLimits in interface OrbitViewLimits

Returns:

Minimum and maximum allowable values for zoom.

limitCenterPosition

public Position limitCenterPosition(View view,
                                    Position position)

Returns a position clamped to the center location limits and center elevation limits specified by this limit object. This method does not modify the specified view's properties, but may use the view as a context for determining how to apply the limits.

Specified by:

limitCenterPosition in interface OrbitViewLimits

Parameters:

view - the view associated with the center position and the property limits.

position - position to clamp to the allowed range.

Returns:

The clamped position.

limitZoom

public double limitZoom(View view,
                        double value)

Returns a distance clamped to the zoom limits specified by this limit object. This method does not modify the specified view's properties, but may use the view as a context for determining how to apply the limits.

Specified by:

limitZoom in interface OrbitViewLimits

Parameters:

view - the view associated with the zoom distance and the property limits.

value - zoom distance to clamp to the allowed range.

Returns:

The clamped value.

reset

public void reset()

Resets all property limits to their default values.

Specified by:

reset in interface ViewPropertyLimits

Overrides:

reset in class BasicViewPropertyLimits

restoreState

public void restoreState(RestorableSupport rs,
                         RestorableSupport.StateObject context)

Specified by:

restoreState in interface ViewPropertyLimits

Overrides:

restoreState in class BasicViewPropertyLimits

setCenterElevationLimits

public void setCenterElevationLimits(double minValue,
                                     double maxValue)

Sets the minimum and maximum values which will limit the orbit view center elevation.

Specified by:

setCenterElevationLimits in interface OrbitViewLimits

Parameters:

minValue - the minimum allowable value for center elevation.

maxValue - the maximum allowable value for center elevation.

setCenterLocationLimits

public void setCenterLocationLimits(Sector sector)

Sets the Sector which will limit the orbit view center latitude and longitude.

Specified by:

setCenterLocationLimits in interface OrbitViewLimits

Parameters:

sector - Sector which will limit the center latitude and longitude.

setZoomLimits

public void setZoomLimits(double minValue,
                          double maxValue)

Sets the minimum and maximum values which will limit the orbit view zoom property.

Specified by:

setZoomLimits in interface OrbitViewLimits

Parameters:

minValue - the mimimum allowable value for zoom.

maxValue - the maximum allowable value for zoom.
