Interface WorkflowInterceptor

public interface WorkflowInterceptor
Provides interception capabilities for workflow engine components. Interceptors allow for cross-cutting concerns such as logging, monitoring, security, and performance measurement to be applied to workflow operations.

Interceptors follow the decorator pattern, wrapping the original component with additional functionality. Each interceptor method receives a delegate component and returns a wrapped version that can add behavior before, after, or around the original operations.

Multiple interceptors can be chained together, with each interceptor wrapping the result of the previous one. This allows for complex interception scenarios where multiple concerns need to be applied.
