reply = $object->invoke( $operation, ... arguments ... );
The invoke() method calls the named repository class operation on the object.
The arguments passed should be as expected by the operation. If the operation returns a scalar value, the call should be called in a scalar context. If it returns an array, it should be invoked in an array context.
The preferred way of achieving the same result is to use the operation name directly. Thus, the following are equivalent but the latter is preferred.
$obj->invoke( "makePort", "1.0", "First port", "Port" ); $obj->makePort( "1.0", "First port", "Port" );
You can also use the invoke_t() method, described in “invoke_t” on page 36 to return additional information.
