svn::class::info

SVN::Class::Info(3pm)					User Contributed Perl Documentation				     SVN::Class::Info(3pm)

NAME

       SVN::Class::Info - Subversion workspace info

SYNOPSIS

	use SVN::Class;

	my $file = svn_file( 'path/to/file' );
	my $info = $file->info;
	printf "repository URL = %s
", $info->url;

DESCRIPTION

       SVN::Class::Info represents the output of the "svn info" command.

METHODS

       SVN::Class::Info does not inherit from SVN::Class, but only Class::Accessor::Fast.

   new( $dir->stdout )
       Creates new SVN::Class::Info instance. The lone argument should be an array ref of output from a call to the SVN::Class object's info()
       method.

       You normally do not need to use this method directly. See the SVN::Class info() method.

   dump
       Returns dump() of the object, just like SVN::Class->dump().

   url
       Get the URL value. Returns a SVN::Class::Repos object.

   path
   wc_root
       Working Copy Root Path

   name
   root
   rev
   node
   schedule
   author
   last_rev
   date
   updated
   checksum
   uuid
       Get/set the info params. These are really only useful as accessors (getters).

ACKNOWLEDGEMENTS

       I looked at SVN::Agent before starting this project. It has a different API, more like SVN::Client in the SVN::Core, but I cribbed some of
       the ideas.
