Detailed Description
template<class T>
class gem5::compression::DictionaryCompressor< T >::UncompressedPattern
A pattern containing the original uncompressed data.
This should be the worst case of every pattern factory, where if all other patterns fail, an instance of this pattern is created.

Decompress the pattern.
Each pattern has its own way of interpreting its data.
- Parameters
-
dict_bytes The bytes in the corresponding matching entry.
- Returns
- The decompressed pattern.
