Description copied from interface: CelFunctionResolver

Finds a specific function overload to invoke based on given parameters.

Specified by:

findOverloadMatchingArgs in interface CelFunctionResolver

Parameters:

functionName - the logical name of the function being invoked.

overloadIds - A list of function overload ids. The dispatcher selects the unique overload from this list with matching arguments.

args - The arguments to pass to the function.

Returns:

an optional value of the resolved overload.

Throws:

CelEvaluationException - if the overload resolution is ambiguous,
