public interface FunctionNode extends Node

Known direct subclasses

`GetSearchStringParameterNode`	`FunctionNode` that represents the getSearchStringParameter function.
`HasPropertyNode`	`FunctionNode` representing the `hasProperty` query function.
`PropertyDefinedNode`	`FunctionNode` representing the `propertyDefined` query function.
