    - - chemaxon.marvin.space.monitor.AngleMonitor

All Implemented Interfaces:

chemaxon.marvin.space.UsableObject
```
@PublicAPI
public class AngleMonitor
extends MeasurementMonitor
```
Monitor for measuring angle between 3 components, the first 2 determines a line, the second 2 another. The angle will be determined by the 2 lines. Component can be any GraphicComponent with a proper getCoordinates() function returning a vector.

Since:

Marvin 4.0.2
