NAME

       Text::BibTeX::File - interface to whole BibTeX files

SYNOPSIS

          use Text::BibTeX;     # this loads Text::BibTeX::File

          $bib = new Text::BibTeX::File "foo.bib" or die "foo.bib: $!\n";
          # or:
          $bib = new Text::BibTeX::File;
          $bib->open ("foo.bib") || die "foo.bib: $!\n";

          $bib->set_structure ($structure_name,
                               $option1 => $value1, ...);

          $at_eof = $bib->eof;

          $bib->close;

DESCRIPTION

       "Text::BibTeX::File" provides an object-oriented interface to BibTeX files.  Its most
       obvious purpose is to keep track of a filename and filehandle together for use by the
       "Text::BibTeX::Entry" module (which is much more interesting).  In addition, it allows you
       to specify certain options which are applicable to a whole database (file), rather than
       having to specify them for each entry in the file.  Currently, you can specify the
       database structure and some structure options.  These concepts are fully documented in
       Text::BibTeX::Structure.

METHODS

   Object creation, file operations
       new ([FILENAME [,MODE [,PERMS]]])
           Creates a new "Text::BibTeX::File" object.  If FILENAME is supplied, passes it to the
           "open" method (along with MODE and PERMS if they are supplied).  If the "open" fails,
           "new" fails and returns false; if the "open" succeeds (or if FILENAME isn't supplied),
           "new" returns the new object reference.

       open (FILENAME [,MODE [,PERMS]])
           Opens the file specified by FILENAME, possibly using MODE and PERMS.  See IO::File for
           full semantics; this "open" is just a front end for "IO::File::open".

       close ()
           Closes the filehandle associated with the object.  If there is no such filehandle
           (i.e., "open" was never called on the object), does nothing.

       eof ()
           Returns the end-of-file state of the filehandle associated with the object: a true
           value means we are at the end of the file.

   Object properties
       set_structure (STRUCTURE [, OPTION => VALUE, ...])
           Sets the database structure for a BibTeX file.  At the simplest level, this means that
           entries from the file are expected to conform to certain field requirements as
           specified by the structure module.  It also gives you full access to the methods of
           the particular structured entry class for this structure, allowing you to perform
           operations specific to this kind of database.  See "CLASS INTERACTIONS" in
           Text::BibTeX::Structure for all the consequences of setting the database structure for
           a "Text::BibTeX::File" object.

       structure ()
           Returns the name of the database structure associated with the object (as set by
           "set_structure").

       preserve_values ([PRESERVE])
           Sets the "preserve values" flag, to control all future parsing of entries from this
           file.  If PRESERVE isn't supplied, returns the current state of the flag.  See
           Text::BibTeX::Value for details on parsing in "value preservation" mode.
