    • getClass

      OClass getClass(Class<?> iClass)

    • getClass

      OClass getClass(String iClassName)
      Returns the OClass instance by class name.

      If the class is not configured and the database has an entity manager with the requested class as registered, then creates a schema class for it at the fly.

      If the database nor the entity manager have not registered class with specified name, returns null.

      Parameters:
      iClassName - Name of the class to retrieve
      Returns:
      class instance or null if class with given name is not configured.
