Interface BarrageTableLoggers.Factory

All Known Implementing Classes:

BarrageTableLoggers.Factory.Noop

Enclosing class:

BarrageTableLoggers

public static interface BarrageTableLoggers.Factory

Supplies the sinks that BarragePerformanceLog forwards its entries to. Each method is called exactly once, when that singleton is constructed, on whichever thread first uses barrage.

Implementations must not throw and must not return null; either fails the construction of BarragePerformanceLog, and hence the barrage activity that first needed it. An implementation that expects a sink to be unavailable is responsible for that decision itself: catch the failure, log the cause, and return the corresponding Noop so that barrage performance is recorded to the in-memory tables only.
