trait CoordinateFilter extends AnyRef
An interface for classes which use the values of the coordinates in a {link Geometry}. Coordinate filters can be used to implement centroid and envelope computation, and many other functions.
CoordinateFilter is
an example of the Gang-of-Four Visitor pattern.
Note: it is not recommended to use these filters to mutate the coordinates. There is no guarantee that the coordinate is the actual object stored in the source geometry. In particular, modified values may not be preserved if the source Geometry uses a non-default {link CoordinateSequence}. If in-place mutation is required, use {link CoordinateSequenceFilter}.
