Class DescriptorBase

         |
        DescriptorBase
Known Subclasses:
Descriptors base class.

This class is the base of all descriptor classes. It provides common options
related functionality.

Attributes:
  has_options:  True if the descriptor has non-default options.  Usually it
      is not necessary to read this -- just call GetOptions() which will
      happily return the default instance.  However, it's sometimes useful
      for efficiency, and also useful inside the protobuf implementation to
      avoid some bootstrapping issues.
