+=head1 NAME
+
+FS::hardware_type - Object methods for hardware_type records
+
+=head1 SYNOPSIS
+
+  use FS::hardware_type;
+
+  $record = new FS::hardware_type \%hash;
+  $record = new FS::hardware_type { 'column' => 'value' };
+
+  $error = $record->insert;
+
+  $error = $new_record->replace($old_record);
+
+  $error = $record->delete;
+
+  $error = $record->check;
+
+=head1 DESCRIPTION
+
+An FS::hardware_type object represents a device type (a model name or 
+number) assignable as a hardware service (L<FS::svc_hardware)>).
+FS::hardware_type inherits from FS::Record.  The following fields are 
+currently supported:
+
+=over 4
+
+=item typenum - primary key
+
+=item classnum - key to an L<FS::hardware_class> record defining the class 
+to which this device type belongs.
+
+=item model - descriptive model name or number
+
+=back
+
+=head1 METHODS
+
+=over 4
+
+=item new HASHREF
+
+Creates a new record.  To add the record 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 { 'hardware_type'; }
+
+=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 hardware type.  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('typenum')
+    || $self->ut_foreign_key('classnum', 'hardware_class', 'classnum')
+    || $self->ut_text('model')
+  ;
+  return $error if $error;
+
+  $self->SUPER::check;
+}
+
+=item hardware_class
+
+Returns the L<FS::hardware_class> associated with this device.
