EventStream from entries: numbers of pairs of time and record.
This class can handle many events more efficiently than ArrayEventStream because this class generate less objects than ArrayEventStream.
Use this class as below, in loop of data-enumeration:
1. initialize blank stream: streams[tag] ||= MultiEventStream.new 2. add events stream[tag].add(time, record)
# File lib/fluent/event.rb, line 159 def initialize(time_array = [], record_array = []) @time_array = time_array @record_array = record_array end
# File lib/fluent/event.rb, line 172 def add(time, record) @time_array << time @record_array << record end
# File lib/fluent/event.rb, line 164 def dup MultiEventStream.new(@time_array.dup, @record_array.map(&:dup)) end
# File lib/fluent/event.rb, line 189 def each(&block) time_array = @time_array record_array = @record_array for i in 0..time_array.length-1 block.call(time_array[i], record_array[i]) end nil end
# File lib/fluent/event.rb, line 181 def empty? @time_array.empty? end
# File lib/fluent/event.rb, line 177 def repeatable? true end
# File lib/fluent/event.rb, line 168 def size @time_array.size end
# File lib/fluent/event.rb, line 185 def slice(index, num) MultiEventStream.new(@time_array.slice(index, num), @record_array.slice(index, num)) end
