Abstract Value Members

  1. abstract def addGauge(name: String*)(f: ⇒ Float): Gauge

    Add the function f as a gauge with the given name.

    Add the function f as a gauge with the given name. The returned gauge value is only weakly referenced by the StatsReceiver, and if garbage collected will cease to be a part of this measurement: thus, it needs to be retained by the caller. Immortal measurements are made with provideGauge. As with provideGauge, gauges with equal names are added together.

  2. abstract def counter(name: String*): Counter

    Get a Counter with the prefix name.

  3. abstract val repr: AnyRef

    Specifies the representative receiver.

    Specifies the representative receiver. This is in order to expose an object we can use for comparison so that global stats are only reported once per receiver.

  4. abstract def stat(name: String*): Stat

    Get a Stat with the description

    Get a Counter with the prefix name.

    Get a Counter with the prefix name. This method is a convenience for Java programs, but is no longer needed because StatsReceiver#counter is usable from java.

  13. def isNull: Boolean

    Accurately indicates if this is a NullStatsReceiver.

    Accurately indicates if this is a NullStatsReceiver. Because equality is not forwarded via scala.Proxy, this is helpful to check for a NullStatsReceiver.

  17. def provideGauge(name: String*)(f: ⇒ Float): Unit

    Register a function to be periodically measured.

    Register a function to be periodically measured. This measurement exists in perpetuity. Measurements under the same name are added together.

  18. def scope(namespace: String): StatsReceiver

    Prepend namespace to the names of this receiver.

  19. def scopeSuffix(suffix: String): StatsReceiver

    Prepend a suffix value to the next scope.

    Prepend a suffix value to the next scope. stats.scopeSuffix("toto").scope("client").counter("adds") will generate /client/toto/adds

  20. def stat0(name: String): Stat

    Get a Stat with the description.

    Get a Stat with the description. This method is a convenience for Java programs, but is no longer needed because StatsReceiver#counter is usable from java.
