Astro::Catalog::IO::ASCII - base class for ASCII-based catalogues.


  $cat = $ioclass->read_catalog( %args );


This class provides a wrapper for reading ASCII-based catalogues into Astro::Catalog objects. The method should, in general, only be called from the Astro::Catalog configure method.



Read the catalog.

  $cat = $ioclass->read_catalog( %args );

Takes a hash as argument with the list of keywords. Supported options are:

  Data => Contents of catalogue, either as a scalar variable,
          reference to array of lines or reference to glob (file handle).
          This key is used in preference to 'File' if both are present.

  File => File name for catalog on disk. Not used if 'Data' supplied.
          If a file is specified but is called 'default', the default file
          for the class is used.

  ReadOpt => Reference to hash of options to be forwarded onto the
             format specific catalogue reader. See the IO documentation
             for details.

The options are case-insensitive.
