No, it does not work like this. It allows you to embed feature attributes in the symbol name instead, and then the symbol generator can extract the attributes. A symbol name could be something like: chart://histogram?dataSeries=${dataSeriesId}&title=${chartTitle} where dataSeriesId and chartTitle are attributes of the feature. The chart symbol factory would get an Expression out of that name (courtesy of some extra parsing done centrally in the SLDStyleFactory). What you ask, assigning expressions to everything, would just break solid the SLD compliancy, so I (personally) don't consider it a solution. But please, have a look at the proposal, provide feedback on it: http://docs.codehaus.org/display/GEOTOOLS/Dynamic+SLD+Graphic+objects Cheers Andrea |
