SetFunction

public SetFunction(String functionIdSuffix,
                   Datatype<RETURN> returnType,
                   boolean varArgs,
                   List<? extends BagDatatype<AV>> parameterTypes)

Creates instance

Parameters:

functionIdSuffix - suffix to functionId; resulting functionId = parameterType.getTypeParameter().getFuncIdPrefix()+ functionIdSuffix function ID

returnType - return type

varArgs - variable-length parameter (the number of parameters to set function is variable)

parameterTypes - parameter types

Method Detail

newCall

public final FirstOrderFunctionCall<RETURN> newCall(List<Expression<?>> argExpressions,
                                                    Datatype<?>... remainingArgTypes)
                                             throws IllegalArgumentException

Description copied from class: FirstOrderFunction

Returns a function call for calling this function.

Specified by:

newCall in class FirstOrderFunction<RETURN extends Value>

Parameters:

argExpressions - function arguments (expressions)

remainingArgTypes - types of remaining inputs to be passed only at request evaluation time, if not all arguments are specified in argExpressions. Therefore, only their type is checked at this point. The actual argument values will be passed as last parameters when calling BaseFirstOrderFunctionCall.evaluate(org.ow2.authzforce.core.pdp.api.EvaluationContext, Optional, boolean, org.ow2.authzforce.core.pdp.api.value.AttributeValue...) at request evaluation time, via the returned FunctionCall.

Returns:

Function call handle for calling this function which such inputs (with possible changes from original inputs due to optimizations for instance)

Throws:

IllegalArgumentException - if inputs are invalid for this function

eval

protected abstract RETURN eval(Bag<AV>[] bagArgs)
