Syncers are classes that implement the sync policies. This module provides functionality to register syncers and access the list of registered syncers. Each Syncer must register itself with Syncers#register. Each Syncer must implement the following methods:
# Creates a new syncer (A syncer is used for one table sync only) # * sync_helper: a SyncHelper object providing necessary information and functionalities def initialize(sync_helper) # Called to sync the provided difference. # See DirectTableScan#run for a description of the +type+ and +row+ parameters. def sync_difference(type, row) # Provides default option for the syncer. Optional. # Returns a hash with :key => value pairs. def self.default_options
Returns the correct syncer class as per provided options hash
# File lib/rubyrep/syncers/syncers.rb, line 37 def self.configured_syncer(options) syncer_id = options[:syncer] syncer_id ||= options[:replicator] syncers[syncer_id] end
Registers one or multiple syncers. syncer_hash is a Hash with
key:: The adapter symbol as used to reference the syncer value:: The class implementing the syncer
# File lib/rubyrep/syncers/syncers.rb, line 31 def self.register(syncer_hash) @syncers ||= {} @syncers.merge! syncer_hash end
