Annotation Type ProcessEngineComponent

@Target(value=TYPE)
 @Retention(value=RUNTIME)
 @Documented
public @interface ProcessEngineComponent

Indicates that the given bean is an process engine handler. A process engine handler is a bean that is so annotated to respond to events ("states") in a Camunda Platform process. Generically, it is a class that has been adapted to be usable in a Camunda Platform process.

For example, suppose we have registered a BPMN process that has the following declaration:

<service-task camunda:expression = "myBean" id = "confirm-receipt" />

This is a state that will be entered from Camunda Platform and execution will flow through to the bean registered in the context as "myBean." To subscribe to that, a POJO need only implement (optionally) ProcessEngineComponent and, on a method, add State to indicate that the method in particular is tasked with responding to a state. If applied to a bean and there are no org.camunda.bpm.engine.annotations.ProcessEngineComponent annotations present, then one option might be to automatically enlist all public methods as handlers for states whose IDs or names are inferred from the method name:

public void confirmReceipt(..) would be treated the same as

@State( "confirm-receipt") public void confirmReceipt (..),
