Java Source Code / Java Documentation » 6.0 JDK Modules » Java Advanced Imaging » com.sun.media.jai.codec   Source Cross Reference   Class Diagram   Java Document (Java Doc)   com.sun.media.jai.codec.SeekableStream    com.sun.media.jai.codec.FileSeekableStream FileSeekableStream public class FileSeekableStream extends SeekableStream (Code) A subclass of SeekableStream that takes its input from a File or RandomAccessFile. Backwards seeking is supported. The mark() and reset() methods are supported. This class is not a committed part of the JAI API. It may be removed or changed in future releases of JAI. Constructor Summary public   FileSeekableStream(RandomAccessFile file)      Constructs a FileSeekableStream from a RandomAccessFile. public   FileSeekableStream(File file)      Constructs a FileSeekableStream from a File. public   FileSeekableStream(String name)      Constructs a FileSeekableStream from a String path name. Method Summary final public  boolean canSeekBackwards()      Returns true since seeking backwards is supported. final public  void close()      Forwards the request to the real File. final public  long getFilePointer()      Returns the current offset in this stream. final public synchronized  void mark(int readLimit)      Marks the current file position for later return using the reset() method. public  boolean markSupported()      Returns true since marking is supported. final public  int read()      Forwards the request to the real File. final public  int read(byte[] b, int off, int len)      Forwards the request to the real File. final public synchronized  void reset()      Returns the file position to its position at the time of the immediately previous call to the mark() method. final public  void seek(long pos)      final public  int skip(int n)      Constructor Detail FileSeekableStream public FileSeekableStream(RandomAccessFile file) throws IOException(Code) Constructs a FileSeekableStream from a RandomAccessFile. FileSeekableStream public FileSeekableStream(File file) throws IOException(Code) Constructs a FileSeekableStream from a File. FileSeekableStream public FileSeekableStream(String name) throws IOException(Code) Constructs a FileSeekableStream from a String path name. Method Detail canSeekBackwards final public boolean canSeekBackwards()(Code) Returns true since seeking backwards is supported. close final public void close() throws IOException(Code) Forwards the request to the real File. getFilePointer final public long getFilePointer() throws IOException(Code) Returns the current offset in this stream. the offset from the beginning of the stream, in bytes,at which the next read occurs. exception:   IOException - if an I/O error occurs. mark final public synchronized void mark(int readLimit)(Code) Marks the current file position for later return using the reset() method. markSupported public boolean markSupported()(Code) Returns true since marking is supported. read final public int read() throws IOException(Code) Forwards the request to the real File. read final public int read(byte[] b, int off, int len) throws IOException(Code) Forwards the request to the real File. reset final public synchronized void reset() throws IOException(Code) Returns the file position to its position at the time of the immediately previous call to the mark() method. seek final public void seek(long pos) throws IOException(Code) skip final public int skip(int n) throws IOException(Code) Fields inherited from com.sun.media.jai.codec.SeekableStream protected long markPos(Code)(Java Doc) Methods inherited from com.sun.media.jai.codec.SeekableStream public boolean canSeekBackwards()(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) abstract public long getFilePointer() throws IOException(Code)(Java Doc) public synchronized void mark(int readLimit)(Code)(Java Doc) public boolean markSupported()(Code)(Java Doc) abstract public int read() throws IOException(Code)(Java Doc) abstract public int read(byte[] b, int off, int len) throws IOException(Code)(Java Doc) final public boolean readBoolean() throws IOException(Code)(Java Doc) final public byte readByte() throws IOException(Code)(Java Doc) final public char readChar() throws IOException(Code)(Java Doc) final public char readCharLE() throws IOException(Code)(Java Doc) final public double readDouble() throws IOException(Code)(Java Doc) final public double readDoubleLE() throws IOException(Code)(Java Doc) final public float readFloat() throws IOException(Code)(Java Doc) final public float readFloatLE() throws IOException(Code)(Java Doc) final public void readFully(byte[] b) throws IOException(Code)(Java Doc) final public void readFully(byte[] b, int off, int len) throws IOException(Code)(Java Doc) final public int readInt() throws IOException(Code)(Java Doc) final public int readIntLE() throws IOException(Code)(Java Doc) final public String readLine() throws IOException(Code)(Java Doc) final public long readLong() throws IOException(Code)(Java Doc) final public long readLongLE() throws IOException(Code)(Java Doc) final public short readShort() throws IOException(Code)(Java Doc) final public short readShortLE() throws IOException(Code)(Java Doc) final public String readUTF() throws IOException(Code)(Java Doc) final public int readUnsignedByte() throws IOException(Code)(Java Doc) final public long readUnsignedInt() throws IOException(Code)(Java Doc) final public long readUnsignedIntLE() throws IOException(Code)(Java Doc) final public int readUnsignedShort() throws IOException(Code)(Java Doc) final public int readUnsignedShortLE() throws IOException(Code)(Java Doc) public synchronized void reset() throws IOException(Code)(Java Doc) abstract public void seek(long pos) throws IOException(Code)(Java Doc) public int skipBytes(int n) throws IOException(Code)(Java Doc) public static SeekableStream wrapInputStream(InputStream is, boolean canSeekBackwards)(Code)(Java Doc)
