Detailed Description

Preserves one historical answer event separately from a card's current scheduling state.

Parameters

Id	The stable legacy review-log key, conventionally derived from the answer time in Unix milliseconds.
ReviewedAt	The absolute answer instant, including its original offset.
Ease	The raw answer-button number stored by Anki.
Interval	The resulting interval: positive days or negative seconds.
PreviousInterval	The preceding interval using the same positive-day/negative-second encoding.
EaseFactor	The resulting legacy ease factor in per-mille units.
AnswerTime	How long the answer took; valid authored values are non-negative.
ReviewType	Anki's raw numeric review-kind code.

Review records are immutable history and do not recalculate AnkiCard.Scheduling. Native AnkiIO JSON preserves every property and orders records by Id for deterministic output. The legacy package writer stores ID, card ID, ease, intervals, factor, answer time in milliseconds, and review type; it cannot independently encode ReviewedAt and the current legacy package reader does not reconstruct review rows. CrowdAnki-style JSON omits review history and reports that loss. Retain native JSON when exact history must round-trip through AnkiIO.

card.ReviewHistory.Add(new AnkiReviewLog(
    Id: 1_750_000_000_000,
    ReviewedAt: DateTimeOffset.FromUnixTimeMilliseconds(1_750_000_000_000),
    Ease: 3,
    Interval: 14,
    PreviousInterval: 7,
    EaseFactor: 2500,
    AnswerTime: TimeSpan.FromSeconds(2),
    ReviewType: 1));

Property Documentation

◆ AnswerTime

TimeSpan AnkiIO.AnkiReviewLog.AnswerTime = AnswerTime

get

Gets the duration spent answering.

A non-negative duration; legacy APKG output stores whole milliseconds.

Definition at line 68 of file AnkiReviewLog.cs.

◆ Ease

int AnkiIO.AnkiReviewLog.Ease = Ease

get

Gets the raw answer-button selection.

Anki's stored integer code; AnkiIO retains it without enum coercion.

Definition at line 52 of file AnkiReviewLog.cs.

◆ EaseFactor

int AnkiIO.AnkiReviewLog.EaseFactor = EaseFactor

get

Gets the resulting legacy ease factor.

A per-mille value such as 2500 for 250%.

Definition at line 64 of file AnkiReviewLog.cs.

◆ Id

long AnkiIO.AnkiReviewLog.Id = Id

get

Gets the stable legacy review-log key.

A caller-supplied integer, conventionally a Unix-millisecond timestamp.

Definition at line 44 of file AnkiReviewLog.cs.

◆ Interval

int AnkiIO.AnkiReviewLog.Interval = Interval

get

Gets the interval produced by the answer.

Positive days or seconds encoded as a negative integer.

Definition at line 56 of file AnkiReviewLog.cs.

◆ PreviousInterval

int AnkiIO.AnkiReviewLog.PreviousInterval = PreviousInterval

get

Gets the interval that applied before the answer.

Positive days or seconds encoded as a negative integer.

Definition at line 60 of file AnkiReviewLog.cs.

◆ ReviewedAt

DateTimeOffset AnkiIO.AnkiReviewLog.ReviewedAt = ReviewedAt

get

Gets the absolute time represented by this answer event.

A DateTimeOffset preserved exactly by native JSON.

Definition at line 48 of file AnkiReviewLog.cs.

◆ ReviewType

int AnkiIO.AnkiReviewLog.ReviewType = ReviewType

get

Gets Anki's raw review-kind code.

An integer retained without interpretation so unknown future or add-on codes survive native JSON.
