java.lang.Objectorg.eclipse.jdt.internal.compiler.apt.dispatch.ProcessorInfo
public class ProcessorInfo
Cached information associated with a Processor
in the context
of annotation processor dispatch.
This class supports inclusion in a collection by implementing equals() and hashCode(). Its concept of identity is based on the class object of the Processor that it wraps; so, for instance, it is not possible to have a Set that contains more than one instance of a particular Processor class. In fact, it is possible to have more than one instance of a Processor if there are multiple build threads, but within the context of a particular dispatch manager, there will only be one of any given Processor class.

Method Detail |
---|
public boolean computeSupportedAnnotations(Set<TypeElement> annotations, Set<TypeElement> result)
annotations
that are described by annotationTypes
,
and determine whether the processor should be called. A processor will be called if it has
any annotations to process, or if it supports "*", or if it was called in a previous round.
If the return value of this method is true once for a given processor, then it will always be true on
subsequent calls.
annotations
- a set of annotation typesannotationTypes
- a set of names, which may use the wildcard "*", as described in
Processor.getSupportedAnnotationTypes()
.result
- an empty modifiable set, which upon return will contain a subset of annotations
, which may be empty but will not be null.
