List of invertQuery() Examples

Examples of invertQuery()

org.geotools.filter.function.RenderingTransformation.invertQuery()
Given a target query and a target grid geometry returns the query to be used to read the input data of the function This method will be called only if the input data is a feature collection. @param targetQuery @param gridGeometry @return The transformed query, or null if no inversion is possible/meaningful
org.geotools.process.RenderingProcess.invertQuery()
Given a target query and a target grid geometry returns the query to be used to read the input data of the process involved in rendering. This method will be called only if the input data is a feature collection. @param targetQuery @param gridGeometry @return The transformed query, or null if no inversion is possible/meaningful

Examples of org.geotools.filter.function.RenderingTransformation.invertQuery()

            // it's a transformation starting from vector data, let's see if we can optimize the query
            FeatureCollection originalFeatures;
            Query optimizedQuery = null;
            if(transformation instanceof RenderingTransformation) {
                RenderingTransformation tx = (RenderingTransformation) transformation;
                optimizedQuery = tx.invertQuery(renderingQuery, gridGeometry);
            }
            // if we could not find an optimized query no other choice but to just limit
            // ourselves to the bbox, we don't know if the transformation alters/adds attributes :-(
            if(optimizedQuery == null) {
                 Envelope bounds = (Envelope) renderingQuery.getFilter().accept(ExtractBoundsFilterVisitor.BOUNDS_VISITOR, null);
