方法详细资料

getCPtr

public static long getCPtr(EPSG4326 obj)

finalize

protected void finalize()

覆盖:

finalize 在类中 Projection

delete

public void delete()

覆盖:

delete 在类中 Projection

swigCreatePolymorphicInstance

public static EPSG4326 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.

fromInternalScale

public double fromInternalScale(double size)

从类复制的说明: Projection

Converts internal size to meters at the equator.

覆盖:

fromInternalScale 在类中 Projection

参数:

size - The size in the internal coordinate system.

返回:

The approximate size in meters at the equator.

fromWgs84

public MapPos fromWgs84(MapPos wgs84Pos)

根据84坐标转当前投影坐标（因为当前投影是84，所以转换前后结果不变）

覆盖:

fromWgs84 在类中 Projection

参数:

wgs84Pos
-

返回:

toWgs84

public MapPos toWgs84(MapPos mapPos)

根据当前投影坐标转84坐标（因为当前投影是84，所以转换前后结果不变）

覆盖:

toWgs84 在类中 Projection

参数:

mapPos
-

返回:

getName

public java.lang.String getName()

从类复制的说明: Projection

获取投影名称，例如"EPSG:3857"

覆盖:

getName 在类中 Projection

返回:

投影名称

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 Projection

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 Projection

返回:

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