FileRetriever CLASS DESCRIPTION A FileRetriever is an object that performs most of the steps needed to allow a user to open a file and read data from it. It has an open: method which performs the action for the standard Open menu choice. Methods are also provided for saving files programmatically (see open, setFilname: and setDirectory:). A FileRetriever must have a dataDelegate which implements the readDataFromStream: method. It is the responsibility of the dataDelegate to read the data from the stream provided as an argument to this method. A FileRetriever may also have a delegate, which will receive the dataWasRead:success:errorCode message informing the delegate whether or not the data was successfully read from the file. An associated FileSaver instance is also optional. FileSaver CLASS DESCRIPTION A FileSaver is an object that performs most of the steps needed to allow a user to save data to a file.
