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:
  1. An exact match where the types of the arguments match the types of the constructor
  2. An in-exact match where the types we are looking for are subtypes of those defined on the constructor
  3. A match where we are able to convert the arguments into those expected by the constructor, according to the registered type converter.

  Specified by:
    `resolve` in interface `ConstructorResolver`
  Parameters:
    `context` - the current evaluation context
    `typename` - the type upon which to look for the constructor
    `argumentTypes` - the arguments that the constructor must be able to handle
  Returns:
    a ConstructorExecutor that can invoke the constructor, or null if non found
  Throws:
    `AccessException`
