Class RendererRegistry

java.lang.Object

com.arbergashi.charts.internal.RendererRegistry

public final class RendererRegistry
extends Object

Simple registry for renderer factories.

Design notes:

• This registry is intentionally decoupled from concrete renderer packages.
• Renderers (or a module/bootstrapper) should register themselves explicitly.
• The registry does not attempt to Class.forName(...) arbitrary renderers.

Method Details

register

public static void register(String id,
 RendererDescriptor descriptor,
 Supplier<? extends ChartRenderer> factory)

create

public static ChartRenderer create(String id)

Creates a renderer instance by id.

Compatibility: This method may return null if the id is not registered. Prefer createOptional(String) or require(String) in new code.

createOptional

public static Optional<ChartRenderer> createOptional(String id)

Creates a renderer instance by id.

Parameters:

id - registry id

Returns:

an Optional containing a new renderer instance if registered

require

public static ChartRenderer require(String id)

Strict variant: returns a renderer or throws if the id is not registered. This is preferred for framework integrations where missing renderers represent configuration errors.

descriptors

public static Map<String, RendererDescriptor> descriptors()
