class InMemoryStatsReceiver extends WithHistogramDetails with StatsReceiver

An in-memory implementation of StatsReceiver, which is mostly used for testing.

Note that an InMemoryStatsReceiver does not conflate Seq("a", "b") and Seq("a/b") names no matter how they look when printed.

val isr = new InMemoryStatsReceiver
isr.counter("a", "b", "foo")
isr.counter("a/b", "bar")

isr.print(Console.out) // will print two lines "a/b/foo 0" and "a/b/bar 0"

assert(isr.counters(Seq("a", "b", "foo") == 0)) // ok
assert(isr.counters(Seq("a", "b", "bar") == 0)) // fail
