method:close() [NONE]

method:read() [NONE]

  • read

    public int read()
             throws IOException
    
    Reads a single byte of compressed data from the input stream. This method will block until some input can be read and compressed.
    Overrides:
    read in class FilterInputStream
    Returns:
    a single byte of compressed data, or -1 if the end of the uncompressed input stream is reached
    Throws:
    IOException - if an I/O error occurs or if this stream is already closed
    See Also:
    FilterInputStream.in

method:read(byte[],int,int) [NONE]

  • read

    public int read​(byte[] b,
                    int off,
                    int len)
             throws IOException
    
    Reads compressed data into a byte array. This method will block until some input can be read and compressed.
    Overrides:
    read in class FilterInputStream
    Parameters:
    b - buffer into which the data is read
    off - starting offset of the data within b
    len - maximum number of compressed bytes to read into b
    Returns:
    the actual number of bytes read, or -1 if the end of the uncompressed input stream is reached
    Throws:
    IndexOutOfBoundsException - if len > b.length - off
    IOException - if an I/O error occurs or if this input stream is already closed
    See Also:
    FilterInputStream.in

method:skip(long) [CHANGED]

  • skip

    public long skip​(long n)
              throws IOException
    
    Skips over and discards data from the input stream. This method may block until the specified number of bytes are read and skipped. Note: While n is given as a long, the maximum number of bytes which can be skipped is Integer.MAX_VALUE.
    Overrides:
    skip in class FilterInputStream
    Parameters:
    n - number of bytes to be skipped
    Returns:
    the actual number of bytes skipped
    Throws:
    IOException - if an I/O error occurs or if this stream is already closed
    See Also:
    InputStream.skipNBytes(long)
  • skip

    public long skip​(long n)
              throws IOException
    
    Skips over and discards data from the input stream. This method may block until the specified number of bytes are read and skipped. Note: While n is given as a long, the maximum number of bytes which can be skipped is Integer.MAX_VALUE.
    Overrides:
    skip in class FilterInputStream
    Parameters:
    n - number of bytes to be skipped
    Returns:
    the actual number of bytes skipped
    Throws:
    IOException - if an I/O error occurs or if this stream is already closed
  • skip

    public long skip​(long n)
              throws IOException
    
    Skips over and discards data from the input stream. This method may block until the specified number of bytes are read and skipped. Note: While n is given as a long, the maximum number of bytes which can be skipped is Integer.MAX_VALUE.
    Overrides:
    skip in class FilterInputStream
    Parameters:
    n - number of bytes to be skipped
    Returns:
    the actual number of bytes skipped
    Throws:
    IOException - if an I/O error occurs or if this stream is already closed
    See Also:
    InputStream.skipNBytes(long)

method:available() [NONE]

  • available

    public int available()
                  throws IOException
    
    Returns 0 after EOF has been reached, otherwise always return 1.

    Programs should not count on this method to return the actual number of bytes that could be read without blocking

    Overrides:
    available in class FilterInputStream
    Returns:
    zero after the end of the underlying input stream has been reached, otherwise always returns 1
    Throws:
    IOException - if an I/O error occurs or if this stream is already closed

method:markSupported() [NONE]

method:mark(int) [NONE]

method:reset() [NONE]
