processingEnv

provides to the processor
IllegalStateException
- if this method is called more than once.public abstract boolean process(Set<? extends TypeElement> annotations, RoundEnvironment roundEnv)
true
is returned, the annotations are claimed and subsequent
processors will not be asked to process them; if false
is returned, the annotations are unclaimed and subsequent
processors may be asked to process them. A processor may
always return the same boolean value or may vary the result
based on chosen criteria.
The input set will be empty if the processor supports "*"
and the root elements have no annotations. A Processor
must gracefully handle an empty set of annotations.
