[mkgmap-dev] Little assist needed from the style code implementors

Hi, I have rather finished the changes for the new multipolygon line/polygon tag handling (see http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2010q3/008977.html). But I need some quick help from someone who known the Java internals of the style processing. All line rules should be executed only if the line contains the tag "mkgmap:styleusage=line" or if the tag is not set. The same for polygons with "mkgmap:styleusage=polygon". I think this should be easy with an AndOp? But I don't know how to set this rule to the lines/polygons RuleSet in StyleImpl. Any suggestions? Thanks! WanMil
