Interface FunctionResolver

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface FunctionResolver

Used for realizing FunctionCall expressions to produce a RiskscapeFunction that can be used during execution of RealizedExpression.evaluate(Object).

Method Summary

Modifier and Type	Method	Description
ResultOrProblems<RiskscapeFunction>	resolve(RealizationContext context, FunctionCall functionCall, Type inputType, List<Type> argumentTypes, IdentifiedFunction function)	Attempt to resolve a function against the given criteria.

Method Details

resolve

ResultOrProblems<RiskscapeFunction> resolve(RealizationContext context,
 FunctionCall functionCall,
 Type inputType,
 List<Type> argumentTypes,
 IdentifiedFunction function)

Attempt to resolve a function against the given criteria.

Parameters:

context - the context in which the function is being resolved, realized and eventually executed

functionCall - the expression that is being matched

inputType - the type that the expression is being evaluated against

argumentTypes - the evaluated types that the function call should expect

function - the function that was found. This will typically be returned unmolested or adapted in some way so that it will accept the given input types.

Returns:

a function that should work with the given inputs, or a failed ResultOrProblems if no RiskscapeFunction could be resolved
