Interface BeanProcessorFactory

public interface BeanProcessorFactory

Factory for creating a Processor that invokes a method on a bean with full support for Camel bean parameter bindings.

When a route contains a .bean() DSL call, Camel delegates processor creation to this factory. The factory implementation lives in camel-bean (loaded via the META-INF service file convention) and supports resolving the target bean from multiple sources: a direct instance, a registry reference by name, a class name, or a Class literal. The method parameter may be omitted to let Camel auto-select the best matching method using the bean-binding algorithm.

The scope parameter controls bean lifecycle: BeanScope.Singleton reuses one shared instance, while BeanScope.Prototype creates a new instance per exchange.
