To aid in generating WSDL, you must provide a bunch of detailed information about your service. This is done via the *dispatch map* and the *data type map*. Normally, all object methods are SOAP accessable (except _name) The dispactch map does not need to be used, but aids the server class in knowing what parameters are used with the functions For multiple OUT parameters, you MUST use the dispatch mapping If you use dispatch mapping, you MUST have a map for each SOAP function IN: An array of IN parameters for the method OUT: An array of OUT parameters for the method ALIAS: Can be used to specify a PHP function to handle the SOAP call (usefull for handling SOAP calls that use PHP keywords) __dispatch_map['echoStructAsSimpleTypes'] = array( 'in' => array('inputStruct' => '{http://soapinterop.org/xsd}SOAPStruct'), 'out' => array('outputString' => 'string', 'outputInteger' => 'int', 'outputFloat' => 'float'), 'alias' => 'myEchoStructAsSimpleTypes' ); $this->__dispatch_map['echoStringSimple'] = array( 'in' => array('inputStringSimple' => 'string'), 'out' => array('outputStringSimple' => 'string'), ); ?>]]>
