DESCRIPTION

       An SVN::Dump object represents a Subversion dump.

       This module follow the semantics used in the reference document (the file
       notes/fs_dumprestore.txt in the Subversion source tree):

       •   A dump is a collection of records (SVN::Dump::Record objects).

       •   A record is composed of a set of headers (a SVN::Dump::Headers object), a set of
           properties (a SVN::Dump::Property object) and an optional bloc of text (a
           SVN::Dump::Text object).

       •   Some special records ("delete" records with a "Node-kind" header) recursively contain
           included records.

       Each class has a "as_string()" method that prints its content in the dump format.

       The most basic thing you can do with SVN::Dump is simply copy a dump:

           use SVN::Dump;

           my $dump = SVN::Dump->new( { file => 'mydump.svn' } );
           $dump->next_record;          # read the format header
           $dump->next_record;          # read the uuid header
           print $dump->as_string();    # only print the dump header

           while( $rec = $dump->next_record() ) {
               print $rec->as_string();
           }

       After the operation, the resulting dump should be identical to the original dump.

METHODS

       SVN::Dump provides the following methods:

       new( \%args )
           Return a new SVN::Dump object.

           The argument list is a hash reference.

           If the SVN::Dump object will read information from a file, the arguments "file" is
           used (as usal, "-" means "STDIN"); if the dump is read from a filehandle, "fh" is
           used.

           Extra options will be passed to the SVN::Dump::Reader object that is created.

           If the SVN::Dump isn't used to read information, the parameters "version" and "uuid"
           can be used to initialise the values of the "SVN-fs-dump-format-version" and "UUID"
           headers.

       next_record()
           Return the next record read from the dump.  This is a SVN::Dump::Record object.

       version()
       format()
           Return the dump format version, if the version record has already been read, or if it
           was given in the constructor.

       uuid()
           Return the dump UUID, if there is an UUID record and it has been read, or if it was
           given in the constructor.

       as_string()
           Return a string representation of the dump specific blocks (the "format" and "uuid"
           blocks only).
