All Implemented Interfaces:
Serializable, Comparable<SevenZMethod>

public enum SevenZMethod extends Enum<SevenZMethod>
The (partially) supported compression/encryption methods used in 7z archives.

All methods with a _FILTER suffix are used as preprocessors with the goal of creating a better compression ratio with the compressor that comes next in the chain of methods. 7z will in general only allow them to be used together with a "real" compression method but Commons Compress doesn't enforce this.

The BCJ_ filters work on executable files for the given platform and convert relative addresses to absolute addresses in CALL instructions. This means they are only useful when applied to executables of the chosen platform.
