Classes

Decayer

Decayer is implemented by connection managers supporting decaying tags.

DecayingTag

Represents a decaying tag. The tag is a long-lived general object, used to operate on tag values for peers.

DecayingValue

A decaying tag is one whose value automatically decays over time.

Functions

bumpOverwrite() → BumpFn

Replaces the current value of the tag with the incoming one.

bumpSumBounded(int min, int max) → BumpFn

Keeps summing the incoming score, keeping it within a min, max range.

bumpSumUnbounded() → BumpFn

Common bump functions Adds the incoming value to the peer's score.

decayExpireWhenInactive(Duration after) → DecayFn

Expires a tag after a certain period of no bumps.

decayFixed(int minuend) → DecayFn

Subtracts from by the provided minuend, and deletes the tag when first reaching 0 or negative.

decayLinear(double coef) → DecayFn

Applies a fractional coefficient to the value of the current tag, rounding down. It erases the tag when the result is zero.

decayNone() → DecayFn

Common decay functions Applies no decay.

Typedefs

BumpFn = int Function(DecayingValue value, int delta)

BumpFn applies a delta onto an existing score, and returns the new score.

DecayFn = (int, bool) Function(DecayingValue value)

DecayFn applies a decay to the peer's score. The implementation must call DecayFn at the interval supplied when registering the tag.
