 org.geotools.filter.visitor.DefaultFilterVisitor
All known Subclasses: org.geotools.filter.FilterAttributeExtractor,
| DefaultFilterVisitor | | public class DefaultFilterVisitor implements FilterVisitor,ExpressionVisitor(Code) | | A basic implementation of the FilterVisitor interface.
This class implements the full FilterVisitor interface and will visit every Filter member of a
Filter object. This class performs no actions and is not intended to be used directly, instead
extend it and overide the methods for the Filter type you are interested in. Remember to call the
super method if you want to ensure that the entier filter tree is still visited. This class can
take an ExpressionVisitor as a construction parameter, if provided it will be called for each
expression in the Filter object.
FilterVisitor allFids = new DefaultFilterVisitor(){
public Object visit( Id filter, Object data ) {
Set set = (Set) data;
set.addAll(filter.getIDs());
return set;
}
};
Set set = (Set) myFilter.accept(allFids, new HashSet());
