Method Summary

Modifier and Type	Method and Description
pack-priv void	finish()
public int	read() Implements abstract javax.imageio.stream.ImageInputStreamImpl.read. Implements javax.imageio.stream.ImageInputStream.read. Reads a single byte from the stream and returns it as an integer between 0 and 255.
public int	read(byte[] b, int off, int len) Implements abstract javax.imageio.stream.ImageInputStreamImpl.read. Implements javax.imageio.stream.ImageInputStream.read. Reads up to `len` bytes from the stream, and stores them into `b` starting at index `off`.
public void	write(byte[] b, int off, int len) Implements abstract javax.imageio.stream.ImageOutputStreamImpl.write. Implements javax.imageio.stream.ImageOutputStream.write. Writes a sequence of bytes to the stream at the current position.
public void	write(int b) Implements abstract javax.imageio.stream.ImageOutputStreamImpl.write. Implements javax.imageio.stream.ImageOutputStream.write. Writes a single byte to the stream at the current position.

public int read() throws IOException Implements abstract javax.imageio.stream.ImageInputStreamImpl.read. Implements javax.imageio.stream.ImageInputStream.read. Doc from javax.imageio.stream.ImageInputStream.read. Reads a single byte from the stream and returns it as an integer between 0 and 255. If the end of the stream is reached, -1 is returned. The bit offset within the stream is reset to zero before the read occurs. Annotations @Override Exceptions IOException: if an I/O error occurs.

public int read(byte[] b, int off, int len) throws IOException Implements abstract javax.imageio.stream.ImageInputStreamImpl.read. Implements javax.imageio.stream.ImageInputStream.read. Doc from javax.imageio.stream.ImageInputStream.read. Reads up to `len` bytes from the stream, and stores them into `b` starting at index `off`. The number of bytes read is returned. If no bytes can be read because the end of the stream has been reached, `-1` is returned. The bit offset within the stream is reset to zero before the read occurs. Annotations @Override Exceptions IOException: if an I/O error occurs.

Reads up to len bytes from the stream, and stores them into b starting at index off. The number of bytes read is returned. If no bytes can be read because the end of the stream has been reached, -1 is returned.

The bit offset within the stream is reset to zero before the read occurs.

write	back to summary
public void write(byte[] b, int off, int len) throws IOException Implements abstract javax.imageio.stream.ImageOutputStreamImpl.write. Implements javax.imageio.stream.ImageOutputStream.write. Doc from javax.imageio.stream.ImageOutputStream.write. Writes a sequence of bytes to the stream at the current position. If `len` is 0, nothing is written. The byte `b[off]` is written first, then the byte `b[off + 1]`, and so on. If the bit offset within the stream is non-zero, the remainder of the current byte is padded with 0s and written out first. The bit offset will be 0 after the write. Implementers can use the `flushBits` method of `ImageOutputStreamImpl` to guarantee this. Annotations @Override Exceptions IOException: if an I/O error occurs.
