ClockHop class final

One hop: how the previous clock in the chain maps onto node's.

Constructors

ClockHop({required String node, required String via, required double offset, double drift = 0, double at = 0, double uncertainty = 0, double? latency, double? jitter, double? held})

const

ClockHop.fromJson(Map<String, Object?> j)

factory

Properties

at → double

The time on the previous clock that offset is exact for.

final

drift → double

How fast offset changes, in seconds per second of the previous clock (so 1e-5 is 10 ppm). Zero when not estimated.

final

hashCode → int

The hash code for this object.

no setter, inherited

held → double?

Mean time a sample spent at node between arriving and being handed on, in seconds, or null if node has not measured it: waiting to be collected (a polling interval), to be put in a chunk, or in a queue.

final

jitter → double?

Standard deviation of latency, or null.

final

latency → double?

Mean time from a sample's timestamp to its arrival at node, in seconds, or null if node has not measured it.

final

node → String

The node whose clock this hop maps onto, and where latency was measured: a host name, a node uId.

final

offset → double

Seconds to add to a time on the previous clock, at at, to get node's clock. Same sign convention as MessageTiming.clockOffset.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

uncertainty → double

Error bound on offset: the full round-trip time of the probe behind it, so the true offset lies within ±uncertainty/2. Same convention as MessageTiming.uncertainty.

final

via → String

The transport the hop crossed: lsl, bridge, webrtc, websocket.

final

Methods

inverse({required String node}) → ClockHop

The same hop walked backwards: node's clock onto the previous one.

map(double t) → double

t on the previous clock, mapped onto node's.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, Object?>

toString() → String

A string representation of this object.

override

withLatency(double? latency, double? jitter, {double? held}) → ClockHop

held is kept unless given.

Operators

operator ==(Object other) → bool

The equality operator.
