public FilterFunction_buffer()
evaluate
public Object evaluate(Object feature)
- Description copied from class:
DefaultExpression
- This method checks if the object is an instance of
Feature
and
if so, calls through to #evaluate(Feature)
. This is done
to maintain backwards compatability with previous version of Expression api
which depended on Feature. If the object is not an instance of feature
the super implementation is called.
- Specified by:
evaluate
in interface Expression
- Overrides:
evaluate
in class DefaultExpression
invert
public ReferencedEnvelope invert(ReferencedEnvelope renderingEnvelope)
- Returns an expanded rendering envelope if the buffering size is not using feature attributes.
If the buffering size is feature dependent the user will have to expand
the rendering area via the renderer buffer parameter
- Specified by:
invert
in interface GeometryTransformation
- Returns:
