FilterFunction_vertices
public FilterFunction_vertices()
getArgCount
public int getArgCount()
- Description copied from class:
FunctionExpressionImpl
- Gets the number of arguments that are set.
- Specified by:
getArgCount
in interface FunctionExpression
- Specified by:
getArgCount
in class FunctionExpressionImpl
- Returns:
- the number of args.
evaluate
public Object evaluate(Object feature,
Class context)
- Description copied from class:
ExpressionAbstract
- Default implementation delegates handling of context
conversion to Value utility class.
Subclasses are expected to make use of the Value utility class
(as the easiest way to provide value morphing in confirmance with
the Filter specification).
- Specified by:
evaluate
in interface Expression
- Overrides:
evaluate
in class ExpressionAbstract
