public class SimplySupportedFileFormat

extends SupportedFileFormat

a class encapsulating file formats that are supported through developer-provided FormatHandlers.

See FileFormat for a full description of the purpose of this class.

Supporting New File Formats

This class provides a simple way to represent a format that is supported by a simple FormatHandler. To use this class, one passes all of the FileFormat parameters--including the specific FormatHandler class name to use--to the constructor. The createFormatHandler() will then instantiate the FormatHandler class by passing the data source object (usually a File or URL) to the FormatHandler(Object) constructor.
