FilterFunction_max
public FilterFunction_max()
getArgCount
public int getArgCount()
- Description copied from class:
FunctionExpressionImpl
- Gets the number of arguments that are set.
- Specified by:
getArgCount
in interface FunctionExpression
- Overrides:
getArgCount
in class FunctionExpressionImpl
- Returns:
- the number of args.
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
