Interface DynamicWorkflow

public interface DynamicWorkflow

Use DynamicWorkflow to implement any number of workflow types dynamically. When a workflow implementation type that extends DynamicWorkflow is registered, it is used to implement any workflow type that is not implicitly registered with the Worker. Only one type that implements DynamicWorkflow per worker is allowed.

The main use case for DynamicWorkflow is an implementation of custom Domain Specific Languages (DSLs). A single implementation can implement a workflow type whose definition is dynamically loaded from some external source.

Use Workflow.getInfo() to query information about the workflow type that should be implemented dynamically.

Use Workflow.registerListener(Object) to register signal and query listeners. Consider using DynamicSignalHandler and DynamicQueryHandler to implement handlers that can support any signal or query type dynamically.

All the determinism rules still apply to workflows that implement this interface.
