The ImageInputStream interface unifies streaming and
file-based operations. An abstract base class,
ImageInputStreamImpl is provided to simplify writing
a new ImageInputStream class. Concrete implementation
classes (FileImageInputStream,
FileCacheImageInputStream, and
MemoryCacheImageInputStream) are provided that allow
input to come from a File or InputStream
with or without the use of a temporary cache file.
The ImageOutputStream interface performs an analogous
function for output. An abstract base class,
ImageOutputStreamImpl is provided, along with
concrete implementation classes (FileImageOutputStream,
FileCacheImageOutputStream, and
MemoryCacheImageOutputStream) are provided that allow
output to go to a File or OutputStream with
or without the use of a temporary cache file.
The IIOByteBuffer class provides an alternative way to
perform reads of sequences of bytes that reduces the amount of
internal data copying.
