Package de.bmiag.tapir.annotationprocessing

Class AnnotationProcessorProvider

java.lang.Object

de.bmiag.tapir.annotationprocessing.AnnotationProcessorProvider

public class AnnotationProcessorProvider
extends java.lang.Object

Singleton which provides the annotation processor for a given processorKey. This class is needed to determine the processor of annotations which are annotated by DynamicActive at runtime.

It does so by scanning for {processorKey}.processor files in the classpath's META-INF folders. The AnnotationProcessorProvider expects a properties file which has exactly one key value pair. The key is the annotation processor's class name and the value is the order which is used to calculate the precedence if multiple annotations processors feel responsible.

Since:

2.0.0
