Class SingleParameterTypedFirstOrderFunction<RETURN_T extends Value,PARAM_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.SingleParameterTypedFirstOrderFunction<RETURN_T,PARAM_T>

Type Parameters:

RETURN_T - function return type

PARAM_T - single/common parameter type

All Implemented Interfaces:

Function<RETURN_T>, PdpExtension, PrimitiveValue, Value

Direct Known Subclasses:

ComparisonFunction, DatatypeConversionFunction, EqualTypeMatchFunction, FirstOrderBagFunctions.BagSize, FirstOrderBagFunctions.PrimitiveToBag, FirstOrderBagFunctions.SetFunction, FirstOrderBagFunctions.SingletonBagToPrimitive

public abstract class SingleParameterTypedFirstOrderFunction<RETURN_T extends Value,PARAM_T extends Value>
extends FirstOrderFunction<RETURN_T>

Superclass of "first-order" functions of single-type parameters, i.e. all parameters have the same datatype. Supplies several useful methods, making it easier to implement such "first-order" function.

Constructor Detail

SingleParameterTypedFirstOrderFunction

public SingleParameterTypedFirstOrderFunction(String name,
                                              Datatype<RETURN_T> returnType,
                                              boolean varargs,
                                              List<? extends Datatype<PARAM_T>> parameterTypes)
                                       throws IllegalArgumentException

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. Note: the "? extends" allows using BagDatatype.

Throws:

IllegalArgumentException - if ( name == null || returnType == null || parameterTypes == null || parameterTypes.size() < 1 )
