This PR serves as a PoC to enable reactive context bindings to support the following use cases:
ContextWatcher
to use a filter function to watch the contextContextWatcher
maintains a cache of matched bindings/values. The list can be updated after initialization upon events from the context.ContextWatcher
to the context chain to receive notifications.@inject.filter
with the option to receive a live of list of matching binding values. Reimplement@inject.tag
to leverage it.Checklist
