Detailed Description

template<class T>
class gem5::compression::DictionaryCompressor< T >::Pattern

The compressed data is composed of multiple pattern entries.

To add a new pattern one should inherit from this class and implement isPattern() and decompress(). Then the new pattern must be added to the PatternFactory declaration in crescent order of size (in the DictionaryCompressor class).
