Method Detail

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
