Class ReportStore

java.lang.Object

tech.nmfin.algoquant.web.ReportStore

public final class ReportStore
extends Object

App-independent metadata and serialization over the immutable snapshot backend.

Using this example. Persists and retrieves typed app reports over SnapshotStore. Use the app namespace with the saved identifier so different tools share storage without mixing report types; reports are snapshots of computed results rather than instructions to recompute with current prices.
