Macros that build the process_all/process_insert/process_update/process_delete
callbacks invoked by WalEx.Events.EventModules for each subscribed table.
Used by host applications via use WalEx.Event, name: MyApp. The on_event/2,
on_insert/4, on_update/4, and on_delete/4 macros expand into the
appropriate process_* functions on the host module.
Summary
Functions
Defines process_delete/1 on the caller for events on name matching filters.
Defines process_all/1 on the caller module.
Defines process_all/1 for a specific table; same shape as on_insert/4 but matches every event type.
Defines process_insert/1 on the caller for events on name matching filters.
Defines process_update/1 on the caller for events on name matching filters.
Fans events out to each function in functions, running them in independent
Tasks. Each function may be an atom (a function in the caller's module) or a
{Module, function} tuple.
Functions
Defines process_delete/1 on the caller for events on name matching filters.
Defines process_all/1 on the caller module.
With :all, the block receives every event in the transaction. With a table
name, the block receives only events for that table after applying
filters (:unwatched_records, :unwatched_fields) and dispatching to
functions.
