Class Summary |
| AdaptiveUnigramModel |
Provides an adaptive model based on bytes observed in the input
stream. |
| ArithCodeInputStream |
An input stream which uses a statistical model and arithmetic
coding for decompression of encoded bytes read from an underlying
input stream. |
| ArithCodeOutputStream |
A filter output stream which uses a statistical model and
arithmetic coding for compression of bytes read from an underlying
arithmetic encoder. |
| ArithCoder |
A generic arithmetic coding subclass containing elements common to
both arithmetic decoding and arithmetic coding. |
| ArithDecoder |
Performs arithmetic decoding, converting bit input into
cumulative probability interval output. |
| ArithEncoder |
Performs arithmetic encoding, converting cumulative probability
interval input into bit output. |
| BitInput |
Reads input from an underlying input stream a bit at a time. |
| BitOutput |
Writes to an underlying output stream a bit at a time. |
| ByteBuffer |
Stores a queue of bytes in a buffer with a maximum size. |
| ByteSet |
A set of bytes. |
| Converter |
Package utility class for converting integers to bytes and back
again in a uniform manner. |
| ExcludingAdaptiveUnigramModel |
Package class for use by the PPMModel. |
| PPMCompress |
Command-line function for compressing files or streams. |
| PPMDecompress |
Command-line function for decompressing files or streams. |
| PPMModel |
Provides a cumulative, adaptive byte model implementing
prediction by partial matching up to a specified maximum context size. |
| PPMNode |
A node in a depth-bounded suffix tree that represents counts of
sequences of bytes. |
| Test |
Runs test suite for arithmetic coding and decoding with all of th esupplied
compression models from Test.main(java.lang.String[]). |
| TestSet |
Package local helper class to compute statistics for a set
of compression experiments. |
| TestStatistics |
Package local helper class to compute statistics for a single
compression experiment. |
| TokenStreamEncoder |
Model of a sequence of tokens. |
| UniformModel |
A singleton uniform distribution byte model. |
