Interface ImplementationProcessor

All Known Implementing Classes:

AutowireProcessor, ComponentNameProcessor, ContextProcessor, DefaultProcessor, DestroyProcessor, ImplementationProcessorSupport, InitProcessor, MonitorProcessor, ParentContextProcessor, PropertyProcessor, PropertyReferenceValidator, ReferenceProcessor, ScopeProcessor, SDOHelperProcessor, ServiceProcessor

public interface ImplementationProcessor

Implementations process a Java class and contribute to a ComponentType or provide some validation function. Implementations may contribute to defined ComponentType metadata, a general ComponentType extensibility element, or a more specific Java extensibility element, which is associated with JavaExtensibilityElement and stored in the ComponentType's extensibility collection. Processors will typically use JavaExtensibilityHelper#getExtensibilityElement(org.apache.tuscany.model.assembly.Extensible), which provides methods for retrieving the Java extensibility element.

In the runtime, a ComponentTypeIntrospector system service introspects component implementation types when an assembly is loaded, calling out to registered processors in the order defined by ComponentTypeIntrospector#introspect(Class). Generally, processors are also system services which register themeselves with a ComponentTypeIntrospector. For convenience, a processor implementation can extend <@link org.apache.tuscany.core.config.processor.ImplementationProcessorSupport}, which provides mechanisms for doing this.

There are a series of bootsrap, or primordial, processors configured in the runtime, and they serve as examples of how an ImplementationProcessor can be implemented.
