FILE GUIDE · KEY SECTIONS

Names for added, updated and deleted UI records

ChangeType is a small enum that describes how an item changed when notifying a consumer.

Line 9 ↗

Describe the event without carrying the item

CT_NEW, CT_UPDATED and CT_DELETED distinguish three operations. The enum contains no identifier, payload or callback machinery; those must accompany it in the interface using it. Deletion here names an event and does not itself erase a wallet or blockchain record.
