Class PriceHistory

java.lang.Object

ai.redouble.demo.pricing.PriceHistory

public final class PriceHistory
extends Object

The logic of "which price is current", with no model in it. Every mention from every document is placed under its product (the canonicalizer's groups say which names are one product), then per audience and currency the prices the documents present as in force compete by date, as of the day the run answers for: the latest one dated on or before that day is current, one dated after it is scheduled, every other statement of the same amount confirms the current one, the earlier ones with another amount are superseded by it, two that disagree on the same latest date are a conflict for a person, and one stated by a document with no date cannot be ranked and says so. What a document itself calls a former price, a proposal, or a cost never competes; a discontinuation dates the product's end. A point's date is the price's own effective date, else the statement's date, else the document's.
