Constructor Detail

AirspaceLayer

public AirspaceLayer()

Creates a new Airspace with an empty collection of Airspaces.

Method Detail

addAirspace

public void addAirspace(Airspace airspace)

Adds the specified airspace to this layer's internal collection. If this layer's internal collection has been overridden with a call to setAirspaces(Iterable), this will throw an exception.

Parameters:

airspace - Airspace to add.

Throws:

IllegalArgumentException - If airspace is null.

IllegalStateException - If a custom Iterable has been specified by a call to setAirspaces.

addAirspaces

public void addAirspaces(Iterable<Airspace> airspaces)

Adds the contents of the specified airspaces to this layer's internal collection. If this layer's internal collection has been overridden with a call to setAirspaces(Iterable), this will throw an exception.

Parameters:

airspaces - Airspaces to add.

Throws:

IllegalArgumentException - If airspaces is null.

IllegalStateException - If a custom Iterable has been specified by a call to setAirspaces.

doPick

protected void doPick(DrawContext dc,
                      Point pickPoint)

Overrides:

doPick in class AbstractLayer

doRender

protected void doRender(DrawContext dc)

Specified by:

doRender in class AbstractLayer

getAirspaces

public Iterable<Airspace> getAirspaces()

Returns the Iterable of Airspaces currently in use by this layer. If the caller has specified a custom Iterable via setAirspaces(Iterable), this will returns a reference to that Iterable. If the caller passed setAirspaces a null parameter, or if setAirspaces has not been called, this returns a view of this layer's internal collection of Airspaces.

Returns:

Iterable of currently active Airspaces.

getDepthOffsetFactor

public Double getDepthOffsetFactor()

getDepthOffsetUnits

public Double getDepthOffsetUnits()

getRenderer

protected AirspaceRenderer getRenderer()

isDrawExtents

public boolean isDrawExtents()

isDrawWireframe

public boolean isDrawWireframe()

isEnableAntialiasing

public boolean isEnableAntialiasing()

isEnableBatchPicking

public boolean isEnableBatchPicking()

isEnableBatchRendering

public boolean isEnableBatchRendering()

isEnableBlending

public boolean isEnableBlending()

isEnableDepthOffset

public boolean isEnableDepthOffset()

isEnableLighting

public boolean isEnableLighting()

removeAirspace

public void removeAirspace(Airspace airspace)

Removes the specified airspace from this layer's internal collection, if it exists. If this layer's internal collection has been overridden with a call to setAirspaces(Iterable), this will throw an exception.

Parameters:

airspace - Airspace to remove.

Throws:

IllegalArgumentException - If airspace is null.

IllegalStateException - If a custom Iterable has been specified by a call to setAirspaces.

removeAllAirspaces

public void removeAllAirspaces()

Clears the contents of this layer's internal Airspace collection. If this layer's internal collection has been overridden with a call to setAirspaces(Iterable), this will throw an exception.

Throws:

IllegalStateException - If a custom Iterable has been specified by a call to setAirspaces.

setAirspaces

public void setAirspaces(Iterable<Airspace> airspaceIterable)

Overrides the collection of currently active Airspaces with the specified airspaceIterable. This layer will maintain a reference to airspaceIterable strictly for picking and rendering. This layer will not modify the Iterable reference. However, this will clear the internal collection of Airspaces, and will prevent any modification to its contents via addAirspace, addAirspaces, or removeAirspaces.

If the specified airspaceIterable is null, this layer will revert to maintaining its internal collection.

Parameters:

airspaceIterable - Iterable to use instead of this layer's internal collection, or null to use this layer's internal collection.

setDepthOffsetUnits

public void setDepthOffsetUnits(Double units)

setDrawExtents
