| ScaledFeature | | public class ScaledFeature implements Feature(Code) | | This class is a wrapper for a Feature and a Feature itself.
It adds a special behavior/property to a feature that is required by deegree DisplayElements.
This special behavior is an additional property named "$SCALE". In opposite to conventional
properties this one can change its value during lifetime of a feature without changing the
underlying feature itself.
The class is use to offer users the opportunity to use the scale of a map within expressions
embedded in SLD rules/symbolizers, i.e. this enables a user to define that a symbol shall appear
in 10m size independ of a map's scale.
