public class Styles

extends java.lang.Object

A collection of style regions. This class performs some of the background work, restructuring the regions as required for applying new styles.

At the moment we restructure so that the entire worksheet region is covered by non-overlapping style regions. Gnumeric appears to have a different strategy, still non-overlapping but it chooses different ways to restructure. We should try to match what Gnumeric does, although it seems to handle any differences relatively smoothly in the limited testing done so far.
