Billboard

public Billboard(long cPtr,
                 boolean cMemoryOwn)

方法详细资料

getCPtr

public static long getCPtr(Billboard obj)

finalize

protected void finalize()

覆盖:

finalize 在类中 VectorElement

delete

public void delete()

覆盖:

delete 在类中 VectorElement

swigCreatePolymorphicInstance

public static Billboard swigCreatePolymorphicInstance(long cPtr,
                                                      boolean cMemoryOwn)

Creates a polymorphic instance of the given native object. This is used internally by the SDK.

参数:

cPtr - The native pointer of the instance.

cMemoryOwn - The ownership flag.

返回:

The created instance.

getBaseBillboard

public Billboard getBaseBillboard()

Returns the base billboard this billboard is attached to.

返回:

The base billboard this billboard is attached to. Null if not attached to a billboard.

setBaseBillboard

public void setBaseBillboard(Billboard baseBillboard)

Attaches this billboard to another billboard, so it will always be drawn relative to the base billboard.
If this billboard has a geometry object assigned to it, it will first be set to null.

参数:

baseBillboard - The billboard this billboard will be attached to.

getBounds

public MapBounds getBounds()

Returns the bounds of this billboard or the base billboard, if there is one.

覆盖:

getBounds 在类中 VectorElement

返回:

The bounds of this billboard.

getRootGeometry

public Geometry getRootGeometry()

Returns the location of the root billboard. If this billboard has a location,
this method is equavalent to the Billboard::getGeometry method. If this billboard is attached
to another billboard, the hierarchy is traveled recursively and the location of the root
billboard is returned.

返回:

The geometry object that defines the location of the root billboard. Null if there's no root billboard.

getGeometry

public Geometry getGeometry()

Returns the geometry object that defines the location of this billboard.

覆盖:

getGeometry 在类中 VectorElement

返回:

The geometry object of this billboard.

setGeometry

public void setGeometry(Geometry geometry)

Sets the location for this billboard. If this billboard is attached
to another billboard, it will first be detached.

参数:

geometry - The new geometry object that defines the location of this billboard.

setPos

public void setPos(MapPos pos)

设置billboard的位置. If this billboard is attached
to another billboard, it will first be detached.

参数:

pos - The new map position that defines the location of this billboard.

getRotation

public float getRotation()

返回billboard的旋转角度

返回:

billboard的旋转角度，以度为单位

setRotation

public void setRotation(float rotation)

Sets the rotation angle of this billboard. The rotation angle is ignored if orientation mode is
set to BillboardOrientation::FACE_CAMERA_BILLBOARD. If the orientation mode is set to
BillboardOrientation::FACE_CAMERA_GROUND then the rotation angle is added to the calculated billboard
angle. If the orientation mode is set to BillboardOrientation::GROUND then the rotation means absolute
rotation, where 0 is points to the north.

参数:

rotation - billboard的新角度，以度为单位

swigGetClassName

public java.lang.String swigGetClassName()

Returns the actual class name of this object. This is used internally by the SDK.

覆盖:

swigGetClassName 在类中 VectorElement

返回:

The class name of this object.

swigGetDirectorObject

public java.lang.Object swigGetDirectorObject()

Returns the connected director object. This is used internally by the SDK.

覆盖:

swigGetDirectorObject 在类中 VectorElement

返回:

The connected director object or null if director is not connected.
