Method Detail
resolve
public ConstructorExecutor resolve(EvaluationContext context, String typeName, List<TypeDescriptor> argumentTypes) throws AccessException
Locate a constructor on the type. There are three kinds of match that might occur:- An exact match where the types of the arguments match the types of the constructor
- An in-exact match where the types we are looking for are subtypes of those defined on the constructor
- A match where we are able to convert the arguments into those expected by the constructor, according to the registered type converter.
- Specified by:

- the type upon which to look for the constructorargumentTypes
- the arguments that the constructor must be able to handle- Returns:
