Constructor Detail

GLArrow2

public GLArrow2(MapRenderer surface,
                Arrow arrow)

Method Detail

startObserving

public void startObserving()

Description copied from interface: GLMapItem2

Start observing the subject. This method should register callback listeners on any properties of the subject that would affect its rendered representation.

Invoking this method should generally refresh the state of the item.

This method may not be invoked on the GL context thread.

Specified by:

startObserving in interface GLMapItem2

Overrides:

startObserving in class GLShape2

stopObserving

public void stopObserving()

Description copied from class: AbstractGLMapItem2

Stops observing the subject. This method should unwind any callback listeners registered via AbstractGLMapItem2.startObserving().

This method may not be invoked on the GL context thread.

Specified by:

stopObserving in interface GLMapItem2

Overrides:

stopObserving in class GLShape2

onStyleChanged

public void onStyleChanged(Shape shape)

Specified by:

onStyleChanged in interface Shape.OnStyleChangedListener

Overrides:

onStyleChanged in class GLShape2

onStrokeColorChanged

public void onStrokeColorChanged(Shape subject)

Specified by:

onStrokeColorChanged in interface Shape.OnStrokeColorChangedListener

Overrides:

onStrokeColorChanged in class GLShape2

onStrokeWeightChanged

public void onStrokeWeightChanged(Shape subject)

Specified by:

onStrokeWeightChanged in interface Shape.OnStrokeWeightChangedListener

Overrides:

onStrokeWeightChanged in class GLShape2

onAltitudeModeChanged

public void onAltitudeModeChanged(Feature.AltitudeMode altitudeMode)

Description copied from interface: MapItem.OnAltitudeModeChangedListener

Called when the altitude mode is changed for the specific item

Specified by:

onAltitudeModeChanged in interface MapItem.OnAltitudeModeChangedListener

Parameters:

altitudeMode - The altitude mode that the map item was set to

ensureLabel

protected boolean ensureLabel()

_validateArrowhead

protected void _validateArrowhead(GLMapView ortho)

getWidgetViewF

protected android.graphics.RectF getWidgetViewF()

Retrieve the bounding RectF of the current state of the Map. This accounts for the OrthoMapView's focus, so DropDowns will be accounted for.

Returns:

_setColor

protected void _setColor(int color)

onPointsChanged

public void onPointsChanged(Shape s)

Specified by:

onPointsChanged in interface Shape.OnPointsChangedListener

getHae

protected double getHae(GLMapView ortho,
                        GeoPoint geo)

onTextChanged

public void onTextChanged(Arrow arrow)

Specified by:

onTextChanged in interface Arrow.OnTextChangedListener

release

public void release()

Overrides:

release in class AbstractGLMapItem2

updateText

protected void updateText(java.lang.String text,
                          int textColor)

_drawArrowHead

protected void _drawArrowHead()

Expects GL_VERTEX_ARRAY client state to be enabled and _arrowHead geometry uploaded as vertex pointer

draw

public void draw(GLMapView ortho,
                 int renderPass)

hitTestImpl

protected HitTestResult hitTestImpl(MapRenderer3 renderer,
                                    HitTestQueryParameters params)

Description copied from class: AbstractGLMapItem2

Perform a hit test on this map item Sub-classes should override this method for hit-testing

Overrides:

hitTestImpl in class AbstractGLMapItem2

Parameters:

renderer - Map renderer

params - Query parameters

Returns:

Hit test result or null if not hit
