+
+FS::msgcat - Object methods for message catalog entries
+
+=head1 SYNOPSIS
+
+ use FS::msgcat qw(gettext);
+
+ #simple interface for retreiving messages...
+ $message = gettext('msgcode');
+ #or errors (includes the error code)
+ $message = geterror('msgcode');
+
+ #maintenance stuff
+ $record = new FS::msgcat \%hash;
+ $record = new FS::msgcat { 'column' => 'value' };
+
+ $error = $record->insert;
+
+ $error = $new_record->replace($old_record);
+
+ $error = $record->delete;
+
+ $error = $record->check;
+
+=head1 DESCRIPTION
+
+An FS::msgcat object represents an message catalog entry. FS::msgcat inherits
+from FS::Record. The following fields are currently supported:
+
+=over 4
+
+=item msgnum - primary key
+
+=item msgcode - Error code
+
+=item locale - Locale
+
+=item msg - Message
+
+=back
+
+=head1 METHODS
+
+=over 4
+
+=item new HASHREF
+
+Creates a new example. To add the example to the database, see L<"insert">.
+
+Note that this stores the hash reference, not a distinct copy of the hash it
+points to. You can ask the object for a copy with the I<hash> method.
+
+=cut
+
+# the new method can be inherited from FS::Record, if a table method is defined
+
+sub table { 'msgcat'; }
+
+=item insert
+
+Adds this record to the database. If there is an error, returns the error,
+otherwise returns false.
+
+=cut
+
+# the insert method can be inherited from FS::Record
+
+=item delete
+
+Delete this record from the database.
+
+=cut
+
+# the delete method can be inherited from FS::Record
+
+=item replace OLD_RECORD
+
+Replaces the OLD_RECORD with this one in the database. If there is an error,
+returns the error, otherwise returns false.
+
+=cut
+
+# the replace method can be inherited from FS::Record
+
+=item check
+
+Checks all fields to make sure this is a valid example. If there is
+an error, returns the error, otherwise returns false. Called by the insert
+and replace methods.
+
+=cut
+
+# the check method should currently be supplied - FS::Record contains some
+# data checking routines
+
+sub check {
+ my $self = shift;
+
+ my $error =
+ $self->ut_numbern('msgnum')
+ || $self->ut_text('msgcode')
+ || $self->ut_text('msg')
+ ;
+ return $error if $error;
+
+ $self->locale =~ /^([\w\@]+)$/ or return "illegal locale: ". $self->locale;
+ $self->locale($1);
+
+ ''; #no error
+}

+
+=item gettext MSGCODE
+
+Returns the full message for the supplied message code.

+ } else {
+ warn "WARNING: message for msgcode $msgcode in locale $locale not found";
+ $msgcode;
+ }
+

+
+=item geterror MSGCODE
+
+Returns the full message for the supplied message code, including the message
+code.
