Class PointF

java.lang.Object

com.jayway.android.robotium.remotecontrol.PointF

All Implemented Interfaces:

java.io.Serializable

public class PointF
extends java.lang.Object
implements java.io.Serializable

From release4.1+, Robotium begins to provide some APIs who use android.graphics.PointF as
parameter. To support this kind of APIs, this class was created, it implements interface Serializable
so that it can be transported as an object thru our TCP protocol.
Example of usage:
At controller side, user can simply call PointF(float, float) to create instance 'pointf'.
and send this object thru the wire.
At the device side, we receive that object 'pointf' and we call toAndroidPointF()
to get an Android's PointF object, which can be used by Robotium's APIs.

This class copy the content of android.graphics.PointF, if that class is modified, we needs
to update this class also. The easiest implementation is to extend the android.graphics.PointF, but
android.jar only provides the stub code which can't be used to instantiate a Class, so I have to
copy the content of android.graphics.PointF
