Enclosing class:
EventPumper
static final class EventPumper.InboundFloodDecisionextends Object
Outcome of EventPumper.evaluateInboundFlood(long, int, int, long, boolean, int, int, RandomSource): whether to reject the incoming connection plus the numbers used in the warn log, so the caller stays side-effect free.

    • InboundFloodDecision

      private InboundFloodDecision(boolean drop, int percent, int lastConnections, int currentConnectionsPerMinute)
      Freeze one accept decision: whether to drop, the nominal rejection chance to render, and the counts it was projected from.
      Parameters:
      drop - true to reject the connection
      percent - nominal rejection chance, 0-100 (0 renders as "1%")
      lastConnections - baseline connections in the previous period
      currentConnectionsPerMinute - projected current accept rate

  • Method Details

    • isDrop

      boolean isDrop()
      Whether to refuse the connection, per the flood decision.
      Returns:
      true if the connection should be rejected

    • getPercent

      int getPercent()
      The nominal share of inbound connections to refuse.
      Returns:
      nominal rejection chance percent (0 renders as "1%")

    • getLastConnections

      int getLastConnections()
      The accept count the rate was measured against.
      Returns:
      baseline connections in the previous full rate period

    • getCurrentConnectionsPerMinute

      int getCurrentConnectionsPerMinute()
      The accept rate the decision was projected from.
      Returns:
      projected current accept rate in connections per minute
