Method Detail

deriveBaseGeometry

@NotNull
public static Observable<Geometry> deriveBaseGeometry(@NotNull
                                                               Observable<Patch> observablePatch)

Derives an Observable from the given observable patch that represents the base of the patch.

This observable geometry will be updated when the given observable patch changes.

Notes:

• When the observable patch contains a null value, the observable ring instance will contain a null value too.
• Observable#setValue will throw an exception for derived instances.

Parameters:

observablePatch - an observable patch from which to derive the base geometry

Returns:

a derived Observable
