Constructor Details

MetricsCat

public MetricsCat(MetricsKey metricsKey,
 BiFunction<MetricsKey,CombMetricsCollector,AbstractMetricsKeyListener> biFunc)

Parameters:

metricsKey - The key corresponding to the listening event, not necessarily the export key(export key may be dynamic)

biFunc - Binary function, corresponding to MetricsKey with less content, corresponding to post event

MetricsCat

public MetricsCat(MetricsKey metricsKey,
 MetricsCat.TpFunction<MetricsKey,MetricsPlaceValue,CombMetricsCollector,AbstractMetricsKeyListener> tpFunc)

Parameters:

tpFunc - Ternary function, corresponding to finish and error events, because an additional record rt is required, and the type of metricsKey is required

Method Details
