| Parameter | Type | Description | 
|---|
| location | LeadPointD | The location of the thumb to test in container coordinates. | 
| testPoint | LeadPointD | The point to test in container coordinates. | 
| hitTestBuffer | double | The hit test buffer is used to make the test point "bigger" to compensate for errors and provide smoother hit-testing. For example, if the buffer value is 2, a square with a length of 4 units around the test point will be used to perform the hit-testing. This value is in container coordinates. | 
| mapper | AnnContainerMapper | The mapper object to use for converting coordinates. Must not be null. | 
            
            Return Value
