SchemaChangeInfo

public final class SchemaChangeInfo extends Object

Contains information about a schema change detected by an ObserverCallback.

This object will be sent when a schema type having a name matching an observer's schema filters (as determined by ObserverSpec.getFilterSchemas()) has been added, updated, or removed.

Note that schema changes may cause documents to be migrated or removed. When this happens, individual document updates will NOT be dispatched via DocumentChangeInfo. The only notification will be of the schema type change via SchemaChangeInfo. Depending on your use case, you may need to re-query the whole schema type when this happens.
