#thread ⇒ Object

AsyncDataProvider allows the user to update data in the background on a schedule and return the most recent data it knows about. The provider will return nil until data is found for the first time

User of this class should subclass it, implement the time_retrieve_interval, and implment update_data.

Examples

class SomeSqlData < AsyncDataProvider

	def initialize
		super()
		@time_retrieve_interval = 120
		@query = "\"SELECT some_data FROM some_table WHERE some_condition > 0;\""
	end

	def update_data(**args)
		sql = Sql.new

		return sql.query(@query)
	end
end
