Package org.ow2.authzforce.core.pdp.api.func

Class MultiParameterTypedFirstOrderFunction<RETURN_T extends Value>

java.lang.Object

org.ow2.authzforce.core.pdp.api.func.BaseFunction<RETURN>

org.ow2.authzforce.core.pdp.api.func.FirstOrderFunction<RETURN_T>

org.ow2.authzforce.core.pdp.api.func.MultiParameterTypedFirstOrderFunction<RETURN_T>

Type Parameters:

RETURN_T - function return type

All Implemented Interfaces:

Function<RETURN_T>, PdpExtension, PrimitiveValue, Value

Direct Known Subclasses:

FirstOrderBagFunctions.BagContains, NonEqualTypeMatchFunction

public abstract class MultiParameterTypedFirstOrderFunction<RETURN_T extends Value>
extends FirstOrderFunction<RETURN_T>

Superclass of "first-order" functions of multi-type parameters, i.e. whose parameters have different datatypes (at least two different). Supplies several useful methods, making it easier to implement such "first-order" function.

Constructor Detail

MultiParameterTypedFirstOrderFunction

public MultiParameterTypedFirstOrderFunction(String name,
                                             Datatype<RETURN_T> returnType,
                                             boolean varargs,
                                             List<? extends Datatype<?>> parameterTypes)

Constructor that creates a function from its signature definition

Parameters:

name - function name

returnType - function return type

varargs - true iff the function takes a variable number of arguments (like Java Method.isVarArgs()

parameterTypes - function parameter types

Throws:

IllegalArgumentException - if ( name == null || returnType == null || parameterTypes == null || parameterTypes.size() < 2 )
