net.simplace.processors.FeatureFilterProcessor

Version: 1.0

This processor performs a FeatureFilter Feature-FilterFeature-Filter specified by a rule string on a org.geotools.feature.FeatureCollection in the ISDSS parameter list. The rule string is parsed by FeatureOperationTreeFilterParser
Required input parameters:

Key source: key where to find the source org.geotools.feature.FeatureCollection or de.schmitzm.geotools.styling.StyledFeatureCollectionInterface in the ISDSS parameter map
Key filter: rule string which defines the filter (or an existing de.schmitzm.geotools.feature.FeatureOperationTreeFilter instance)
Key destParamKey: Output parameter key where the resulting org.geotools.feature.FeatureCollection is stored in (if the input object is a de.schmitzm.geotools.styling.StyledFeatureCollectionInterface or the style parameter is set then the result will be also one)
Key style (optional): Name of the style, defined in the ISDSS configuration, used to style the org.geotools.feature.FeatureCollection.
