TTMSFNCCustomWebPushDB Class

Stores push subscriptions in a dataset and exposes operations to add, update, delete, find, and iterate them. Acts as the base class for the published subscription store component.

API unit family: TMS.TMSFNCWebPushDB Inherits from: TComponent

Syntax

TTMSFNCCustomWebPushDB = class(TComponent)

Remarks

When no external data source is assigned the store creates and persists its own client dataset. Which columns are read and written is controlled through the field map exposed by the published descendant. Operations honor the active optional fields and raise the matching before/after events.
