An adapter (previously called an external performer or EP) is a Java class that provides a mechanism that integrates external third-party classes and actions with Progress Developer Studio for OpenEdge; for instance, an adapter can automate some functions and tasks performed by a server or an external system.
Adapters are the “performers” of Adapter worksteps. Depending on your application requirements, you can use a predefined managed adapter provided by Progress Developer Studio for OpenEdge; or you can develop your own adapters to carry out specific tasks. Progress Developer Studio for OpenEdge provides a series of managed adapters that have complex, specific features. Advanced users can find out more about Managed Adapters in the Managed Adapters Guide.
