Instance Method Details

#configure_cache ⇒ Class

Configures and returns the appropriate cache class based on command-line options.

Determines which cache implementation to use based on command-line flags:

  • If the -M flag is set, uses Documentrix::Documents::MemoryCache

  • Otherwise, resolves and returns the cache class specified in configuration

Falls back to Documentrix::Documents::MemoryCache if configuration resolution fails.

Returns:

  • (Class) —

    The selected cache class for document storage and retrieval.

Raises:

  • (StandardError) —

    If there is an error resolving the configured cache class, logs the error to standard error and falls back to MemoryCache.

  STDERR.puts "Caught #{e.class}: #{e} => Falling back to MemoryCache."
  Documentrix::Documents::MemoryCache
end

#document_cache_class ⇒ Class

Retrieves the cache class specified in the configuration.

This method resolves the cache class name from the application’s configuration to dynamically load the appropriate cache implementation.

Returns:

  • (Class) —

    The cache class referenced by the configuration’s cache setting.

Raises:

  • (NameError) —

    If the configured cache class name does not correspond to an existing constant.
