com.fulcrologic.fulcro.rendering.ident-optimized-render
A render optimization algorithm for refreshing the UI via props tunnelling (setting new props on a component's state in a pre-agreed location). This algorithm analyzes database changes and on-screen components to update components (by ident) whose props have changed.
Prop change detection is done by scanning the database in only the locations that on-screen components are querying (derived by the mounted component idents, and any ident-joins in the queries).

dirty-table-entriesclj/s
(dirty-table-entries old-state new-state idents)Checks the given idents and returns a subset of them where the data they refer to has changed
between old-state and new-state.
Checks the given `idents` and returns a subset of them where the data they refer to has changed between `old-state` and `new-state`.
props->componentsclj/s
(props->components app property-set)Given an app and a property-set: returns the components that query for the items in property-set.
The property-set can be any sequence (ideally a set) of keywords and idents that can directly appear
in a component query as a property or join key.

render!clj/s
(render! app)(render! app {:keys [force-root? root-props-changed?] :as options})The top-level call for using this optimized render in your application.
If :force-root? true is passed in options, then it just forces a keyframe root render; otherwise
it tries to minimize the work done for screen refresh to just the queries/refreshes needed by the
data that has changed.

render-component!clj/s
(render-component! app ident c)Uses the component's query and the current application state to query for the current value of that component's props (subtree). It then sends those props to the component via "props tunnelling" (setting them on a well-known key in component-local state).

render-components-with-ident!clj/s
(render-components-with-ident! app ident)Renders only components that have the given ident.
Renders *only* components that *have* the given ident.
render-dependents-of-ident!clj/s
(render-dependents-of-ident! app ident)Renders components that have, or query for, the given ident.
Renders components that have, or query for, the given ident.
render-stale-components!clj/s
(render-stale-components! app)This function tracks the state of the app at the time of prior render in the app's runtime-atom. It uses that to do a comparison of old vs. current application state (bounded by the needs of on-screen components). When it finds data that has changed it renders all of the components that depend on that data.
