RendererRegistry implements SingletonInterface
Table of Contents
Interfaces
- SingletonInterface
- "empty" interface for singletons (marker interface pattern)
Properties
- $classNames : array<string|int, mixed>
- Registered class names
- $instances : array<string|int, FileRendererInterface>
- Instance cache for renderer classes
Methods
- getRenderer() : FileRendererInterface|null
- Get matching renderer with highest priority
- getRendererInstances() : array<string|int, FileRendererInterface>
- Get all registered renderer instances
- registerRendererClass() : mixed
- Allows to register a Renderer class
- compareRendererPriority() : int
- Compare the priority of two renderer classes Is used for sorting array of Renderer instances by priority We want the result to be ordered from high to low so a higher priority comes before a lower.
- createRendererInstance() : FileRendererInterface
- Create an instance of a certain renderer class
