方法详细资料

doWithAggregate

@Nullable
public MergedAnnotation<A> doWithAggregate(Object context,
 int aggregateIndex)

从接口复制的说明: AnnotationsProcessor

Called when an aggregate is about to be processed. This method may return a non-null result to short-circuit any further processing.

指定者:

doWithAggregate 在接口中 AnnotationsProcessor<Object,MergedAnnotation<A extends Annotation>>

参数:

context - the context information relevant to the processor

aggregateIndex - the aggregate index about to be processed

返回:

a non-null result if no further processing is required

doWithAnnotations

@Nullable
public MergedAnnotation<A> doWithAnnotations(Object type,
 int aggregateIndex,
 @Nullable
 Object source,
 Annotation[] annotations)

从接口复制的说明: AnnotationsProcessor

Called when an array of annotations can be processed. This method may return a non-null result to short-circuit any further processing.

指定者:

doWithAnnotations 在接口中 AnnotationsProcessor<Object,MergedAnnotation<A extends Annotation>>

参数:

type - the context information relevant to the processor

aggregateIndex - the aggregate index of the provided annotations

source - the original source of the annotations, if known

annotations - the annotations to process (this array may contain null elements)

返回:

a non-null result if no further processing is required

process

@Nullable
private MergedAnnotation<A> process(Object type,
 int aggregateIndex,
 @Nullable
 Object source,
 Annotation annotation)

updateLastResult

private void updateLastResult(MergedAnnotation<A> candidate)

finish

@Nullable
public MergedAnnotation<A> finish(@Nullable
 MergedAnnotation<A> result)

从接口复制的说明: AnnotationsProcessor

Get the final result to be returned. By default this method returns the last process result.

指定者:

finish 在接口中 AnnotationsProcessor<Object,MergedAnnotation<A extends Annotation>>

参数:

result - the last early exit result, or null if none

返回:

the final result to be returned to the caller
