    - #### ObjectType

          public ObjectType(String class_name)

      Parameters:
        `class_name` - fully qualified class name, e.g. java.lang.String

  - ### Method Detail

    - #### getInstance

          public static ObjectType getInstance(String class_name)

      Since:
        6.0

    - #### getClassName

          public String getClassName()

      Returns:
        name of referenced class

    - #### hashCode

          public int hashCode()

      Overrides:

      Overrides:
        `equals` in class `Type`
      Returns:

    - #### referencesClass

          @Deprecated
          public boolean referencesClass()

      Deprecated. (since 6.0) this method returns an inaccurate result if the class or interface referenced cannot be found: use referencesClassExact() instead
      If "this" doesn't reference a class, it references an interface or a non-existant entity.

          @Deprecated
          public boolean referencesInterface()

      Deprecated. (since 6.0) this method returns an inaccurate result if the class or interface referenced cannot be found: use referencesInterfaceExact() instead
      If "this" doesn't reference an interface, it references a class or a non-existant entity.

    - #### referencesClassExact

      Return true if this type references a class, false if it references an interface.
      Returns:
        true if the type references a class, false if it references an interface
      Throws:
