# AstropyDumper

class astropy.io.misc.yaml.AstropyDumper(stream, default_style=None, default_flow_style=False, canonical=None, indent=None, width=None, allow_unicode=None, line_break=None, encoding=None, explicit_start=None, explicit_end=None, version=None, tags=None, sort_keys=True)

  Bases: `SafeDumper`

  Custom SafeDumper that represents astropy core objects as well as Python tuple and unicode objects.

  This class is not directly instantiated by user code, but instead is used to maintain the available representer functions that are called when generating a YAML stream from an object. See the PyYaml documentation for details of the class signature.
