reader
fun reader(type: AggregateType, masks: PayloadMasks = PayloadMasks.NONE, reading: (EventRecord) -> EventRecord? = { it }): QueryRecordReader
Reads a stored record of type as the model shows it: each event as reading gives it (its current name and revision, its body upgraded; null leaves it out), its body masked by masks. A record without events (a projection dropped them) is returned as it is.
