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
40 function getMessage() {
41 return $this->mMessage
;
45 * In following PEAR_Error model this could be formatted differently,
46 * but so far it's not.
50 return $this->getMessage();
54 * Returns true if the given object is a WikiError-descended
55 * error object, false otherwise.
57 * @param mixed $object
61 function isError( &$object ) {
62 return is_a( $object, 'WikiError' );
67 * Localized error message object
69 class WikiErrorMsg
extends WikiError
{
71 * @param string $message Wiki message name
72 * @param ... parameters to pass to wfMsg()
74 function WikiErrorMsg( $message/*, ... */ ) {
75 $args = func_get_args();
77 $this->mMessage
= wfMsgReal( $message, $args, true );
84 class WikiXmlError
extends WikiError
{
86 * @param resource $parser
87 * @param string $message
89 function WikiXmlError( $parser, $message = '' ) {
90 $this->mXmlError
= xml_get_error_code( $parser );
91 $this->mMessage
= $message;
92 xml_parser_free( $parser );
95 function getMessage() {
96 return $this->mMessage
. ': ' . xml_error_string( $this->mXmlError
);
