Error processing
Some methods set an error code. You can obtain this error code by sending the currentError message to instances of the ObjectLoader or ObjectDumper. Similarly, you can use the message currentErrorString to obtain the corresponding error message string. You can also use the method hasErrorOccurred to check whether an error occurred during the last operation.
Associated with each error code is an error object, and the value of the error object depends on the returned error code. You can use the message errorObject to obtain the object which is related to or causes the error to occur.
