Examples of org.geowebcache.grid.GridSet.shouldTruncateIfChanged()

org.geowebcache.grid.GridSet.shouldTruncateIfChanged()

Evaluates wheter this GridSet is different engouh from {@code another} so that if thisGridSet were replaced by {@code another} all layers referencing this GridSet should betruncated.

The rule is, if any of the following properties differ: {@link #getBounds()}, {@link #isTopLeftAligned()}, {@link #getTileHeight()}, {@link #getTileWidth()}, {@link #getSrs()}, OR none of the previously mentiond properties differ and {@link #getGrids()} are different, except if both the grids of {@code another} are a supersetof the grids of this gridset (i.e. they are all the same but {@code another} just has morezoom levels}.

@param oldGridSet @param another @return {@code true} if

        final GridSet oldGridSet = gridSetBroker.get(oldGridSetName);
        if (null == oldGridSet) {
            throw new IllegalArgumentException("GridSet " + oldGridSetName + " does not exist");
        }


        final boolean needsTruncate = oldGridSet.shouldTruncateIfChanged(newGridSet);
        if (needsTruncate) {
            log.warning("### Changes in gridset force truncation of affected Tile layers");
            log.info("### Old gridset: " + oldGridSet);
            log.info("### New gridset: " + newGridSet);
        }
