Where errors are generated

The following methods, in the current and in the obsolete API, cause the error return value to be set. You should check this value after an operation to ensure that no error occurred. In addition, the ObjectDumper returns false for failed unload operations, and the ObjectLoader returns nil for failed load operations. You can also use the method hasErrorOccurred to check if an error occurred during the last operation.
