Under each method, its extensions (Q CS XT Z ZZ IB W U): bold and ticked, it exists; struck, it does not. The extensions and what they mean

No method of this class is run on this page: the class reaches files, the network, processes, the clock, chance or sound, and an example run here would only be an example of its effects. Each method carries the explanation the library gives of itself.

Method

Explanation, as the source carries it

init

(no comment in the source: the name reads as a sentence) initno extension

Handle

(no comment in the source: the name reads as a sentence) handleno extension

AdoptHandle

Adopt an engine series OWNED ELSEWHERE (a metric family's child, perf P8): frees any self-created handle, then reads/writes the adopted one. Destroy() will NOT free an adopted handle -- the owner (the family) frees it.no extension

Capacity

(no comment in the source: the name reads as a sentence) capacityno extension

Record

Record a value stamped with the engine's MONOTONIC watch clock (ms since module load) -- the right default for rate/slope math.no extension

RecordAt

Record against a caller-supplied clock (ms). The scope is named at the call site: you brought the clock, you own its semantics.no extension

Count

Samples ever recorded (keeps counting past capacity).no extension

Size

Samples retained in the window (never exceeds Capacity()).no extension

Last

(no comment in the source: the name reads as a sentence) lastno extension

Min

(no comment in the source: the name reads as a sentence) minno extension

Max

(no comment in the source: the name reads as a sentence) maxno extension

Mean

(no comment in the source: the name reads as a sentence) meanno extension

SlopePerMs

Least-squares slope of value over time, per ms of the series' clock: ~0 = stable, positive = growing (the leak detector).no extension

Percentile

Exact nearest-rank percentile over the retained window.no extension

P50

Same as Percentile: Exact nearest-rank percentile over the retained window.no extension

P95

Same as Percentile: Exact nearest-rank percentile over the retained window.no extension

P99

Same as Percentile: Exact nearest-rank percentile over the retained window.no extension

TimeAt

1-based, oldest first, over the retained window.no extension

ValueAt

(no comment in the source: the name reads as a sentence) value atno extension

Values

The retained window as Haro lists (crosses the bridge per item -- for display and small windows, not hot paths).no extension
