org.geotools.filter.expression
Class ToXlinkHrefFunction
java.lang.Object
org.geotools.filter.expression.ToXlinkHrefFunction
- All Implemented Interfaces:
- org.opengis.filter.expression.Expression, org.opengis.filter.expression.Function
public class ToXlinkHrefFunction
- extends java.lang.Object
- implements org.opengis.filter.expression.Function
This function redirects an attribute to be encoded as xlink:href, instead of being encoded as a
full attribute. This is useful in polymorphism, where static client property cannot be used when
the encoding is conditional. This function expects:
- Expression: REFERENCE_VALUE (could be another function or literal)
