Method Detail

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 translated rendering envelope if the offsets are not using feature attributes. If the offsets are feature dependent the user will have to expand the rendering area via the renderer buffer parameter

Specified by:
invert in interface GeometryTransformation
Returns:
