26 * Since PHP4 doesn't have exceptions, here's some error objects
27 * loosely modeled on the standard PEAR_Error model...
31 * @param string $message
33 function WikiError( $message ) {
34 $this->mMessage
= $message;
38 * @return string Plaintext error message to display
41 return $this->mMessage
;
45 * Returns true if the given object is a WikiError-descended
46 * error object, false otherwise.
48 * @param mixed $object
52 function isError( &$object ) {
53 return is_a( $object, 'WikiError' );
58 * Localized error message object
60 class WikiErrorMsg
extends WikiError
{
62 * @param string $message Wiki message name
63 * @param ... parameters to pass to wfMsg()
65 function WikiErrorMsg( $message/*, ... */ ) {
66 $args = func_get_args();
68 $this->mMessage
= wfMsgReal( $message, $args, true );
75 class WikiXmlError
extends WikiError
{
77 * @param resource $parser
78 * @param string $message
80 function WikiXmlError( $parser, $message = '' ) {
81 $this->mXmlError
= xml_get_error_code( $parser );
82 $this->mMessage
= $message;
83 xml_parser_free( $parser );
87 return $this->mMessage
. ': ' . xml_error_string( $this->mXmlError
);
