Class ExtensionAnnotationProcessor

java.lang.Object

javax.annotation.processing.AbstractProcessor

org.pf4j.processor.ExtensionAnnotationProcessor

All Implemented Interfaces:

Processor

public class ExtensionAnnotationProcessor
extends AbstractProcessor

Processes Extension annotations and generates an ExtensionStorage. You can specify the concrete ExtensionStorage via processor's environment options (ProcessingEnvironment.getOptions()) or system property. In both variants the option/property name is pf4j.storageClassName.
