    Abstract + *

    + * RIFF File Format + * A RIFF file consists of a RIFF header followed by zero or more lists and chunks. + *

    + * The RIFF header has the following form: + * 

    + * 'RIFF' fileSize fileType (data)
+ *
    + * where 'RIFF' is the literal FOURCC code 'RIFF', fileSize is a 4-byte value + * giving the size of the data in the file, and fileType is a FOURCC that + * identifies the specific file type. The value of fileSize includes the size + * of the fileType FOURCC plus the size of the data that follows, but does not + * include the size of the 'RIFF' FOURCC or the size of fileSize. The file data + * consists of chunks and lists, in any order. + *

    + * FOURCCs
    + * A FOURCC (four-character code) is a 32-bit unsigned integer created by + * concatenating four ASCII characters. For example, the FOURCC 'abcd' is + * represented on a Little-Endian system as 0x64636261. FOURCCs can contain + * space characters, so ' abc' is a valid FOURCC. The RIFF file format uses + * FOURCC codes to identify stream types, data chunks, index entries, and other + * information. + *

    + * A chunk has the following form: + * 

    + * ckID ckSize ckData
+ *
    + * where ckID is a FOURCC that identifies the data contained in the chunk, + * ckData is a 4-byte value giving the size of the data in ckData, and ckData is + * zero or more bytes of data. The data is always padded to nearest WORD boundary. + * ckSize gives the size of the valid data in the chunk; it does not include + * the padding, the size of ckID, or the size of ckSize. + *

    + * A list has the following form: + * 

    + * 'LIST' listSize listType listData
+ *

    Examples + * + *

    Traversing the raw structure of a RIFF file + *

    To traverse the file structure you must first set up a RIFFVisitor object + * that does something useful at each call to the visit method. Then create an + * instance of a RIFFParser and invoke the #interpret method. + * + * 

    + * class RIFFRawTraversal
+ * .	{
+ * .	static class Visitor
+ * .	implements RIFFVisitor
+ * .		{
+ * .		...implement the visitor interface here...
+ * .		}
+ * .
+ * .	public static void main(String[] args)
+ * .		{
+ * .		try	{
+ * .			Visitor visitor = new Visitor();
+ * .			FileInputStream stream = new FileInputStream(args[0]);
+ * .			RIFFParser p = new RIFFParser();
+ * .			p.interpret(stream,visitor);
+ * .			stream.close();
+ * .			}
+ * .		catch (IOException e) { System.out.println(e); }
+ * .		catch (InterpreterException e)  { System.out.println(e); }
+ * .		catch (AbortedException e)  { System.out.println(e); }
+ * .		}
+ * .	}
+ *
    + * + *

    Traversing the RIFF file and interpreting its content. + *

    Since RIFF files are not completely self describing (there is no information + * that helps differentiate between data chunks, property chunks and collection + * chunks) a reader must set up the interpreter with some contextual information + * before starting the interpreter. + *

    + * Once at least one chunk has been declared, the interpreter will only call the + * visitor for occurences of the declared group chunks and data chunks. The property + * chunks and the collection chunks can be obtained from the current group chunk + * by calling #getProperty or #getCollection. + *
    Note: All information the visitor can obtain during interpretation is only + * valid during the actual #visit... call. Dont try to get information about properties + * or collections for chunks that the visitor is not visiting right now. + * + * 

    + * class InterpretingAnILBMFile
+ * .	{
+ * .	static class Visitor
+ * .	implements RIFFVisitor
+ * .		{
+ * .		...
+ * .		}
+ * .
+ * .	public static void main(String[] args)
+ * .		{
+ * .		try	{
+ * .			Visitor visitor = new Visitor();
+ * .			FileInputStream stream = new FileInputStream(args[0]);
+ * .			RIFFParser p = new RIFFParser();
+ * .			p.declareGroupChunk('FORM','ILBM');

+ * .			p.declarePropertyChunk('ILBM','CMAP');
+ * .			p.declareCollectionChunk('ILBM','CRNG');
+ * .			p.declareDataChunk('ILBM','BODY');
+ * .			p.interpret(stream,visitor);
+ * .			stream.close();
+ * .			}
+ * .		catch (IOException e) { System.out.println(e); }
+ * .		catch (InterpreterException e)  { System.out.println(e); }
+ * .		catch (AbortedException e)  { System.out.println(e); }
