DocumentChangeInfo

Kotlin |Java

public final class DocumentChangeInfo

Contains information about an individual change detected by an ObserverCallback.

This class reports information about document changes, that is, when documents were added, updated or removed.

Changes are grouped by package, database, schema type and namespace. Each unique combination of these items will generate a unique DocumentChangeInfo.

Notifications are only sent for documents whose schema type matches an observer's schema filters (as determined by getFilterSchemas).

Note that document changes that happen during schema migration from calling setSchemaAsync are not reported via this class. Such changes are reported through SchemaChangeInfo.
