PreviewRendererInterface

Interface PreviewRendererInterface

Contract for classes capable of rendering previews of a given record from a table. Responsible for rendering preview header, preview content and wrapping of those two values.

Responsibilities are segmented into three methods, one for each responsibility, which is done in order to allow overriding classes to change those parts individually without having to replace other parts. Rather than relying on implementations to be friendly and divide code into smaller pieces and give them (at least) protected visibility, the key methods are instead required on the interface directly.

Callers are then responsible for calling each method and combining/wrapping the output appropriately.
