callBy

abstract fun callBy(args: Map<KParameter, Any?>): R(source)

Calls this callable with the specified mapping of parameters to arguments and returns the result. Parameter can be omitted from the mapping if it is either optional (KParameter.isOptional) or vararg (KParameter.isVararg). If a parameter is not found in the mapping and cannot be omitted, or its type does not match the type of the provided value, an exception is thrown.
