Overview

Factory for creating Match Finder instances

This factory implements the Factory pattern to create different match finder implementations based on configuration. It provides a clean separation between the configuration (what) and the implementation (how).

Examples:

Creating an SDK-compatible match finder

config = MatchFinderConfig.sdk_config(dict_size: 65536, level: 5)
finder = MatchFinderFactory.create(config)

Creating a simplified match finder

config = MatchFinderConfig.simplified_config(dict_size: 65536)
finder = MatchFinderFactory.create(config)

.create(config) ⇒ MatchFinder, Implementations::SevenZip::LZMA::MatchFinder

Parameters:

Returns:

Raises:

  • (ArgumentError) —

    if configuration is invalid

def self.create(config)
  config.validate!

  case config.mode
  when "sdk"
    Implementations::SevenZip::LZMA::MatchFinder.new(config)
  when "simplified"
    # Use simplified MatchFinder implementation
    MatchFinder.new(config.window_size, config.max_match_length)
  else
    raise ArgumentError, "Unknown match finder mode: #{config.mode}"
  end
end

.from_options(options = {}) ⇒ MatchFinder, Implementations::SevenZip::LZMA::MatchFinder

Create match finder from options hash (convenience method)

Parameters:

  • options (Hash) (defaults to: {}) —

    Options hash

Options Hash (options):

  • :sdk_compatible (Boolean) —

    Use SDK mode

  • :dict_size (Integer) —

    Dictionary size

  • :level (Integer) —

    Compression level

Returns:
