Examples of org.geotools.filter.FilterCapabilities

org.geotools.filter.FilterCapabilities
Represents the Filter capabilities that are supported by a SQLEncoder
Each SQLEncoder class should have one static FilterCapabilities, representing the filter encoding operations that it can successfully perform.
This class is used as one big mask to detect filters that cannot be performed @author Chris Holmes, TOPP @source $URL$ @deprecated use {@link org.opengis.filter.capability.FilterCapabilities}.
