Class IntGauge

java.lang.Object
com.pnfsoftware.jeb.util.collect.IntGauge
public class IntGauge extends Object
An integer gauge is used to define an integer range to be filled. The range must be reasonably small (for larger ranges (million+), a custom implementation relying ISegmentMap may be better suited in terms of memory usage).

Example:
- a range [20, 100] is specified
- calls to record may be used to record partial filling of the gauge:
record(10, 30), record(56, 60), record(0, 10)
- the order of the fillings does not matter; however, overlaps are not allowed:
e.g. if the sub-range [10,30[ was recorded and is present, adding a range [25,40[ would be rejected (record() would return false)
- when the gauge is complete, isComplete() returns true

      public IntGauge(int size)
      Create a gauge whose range goes from 0 to size. The range must be reasonably small (recommendation: less than 1M).

    • IntGauge

      public IntGauge(int begin, int end)
      Create a gauge whose range goes from begin to end (exclusive). The range must be reasonably small (recommendation: less than 1M).
      Parameters:
      begin -
      end -
