可以查阅 官方文档 ：

Processes a set of annotation types on type elements originating from the prior round and returns whether or not these annotation types are claimed by this processor. If true is returned, the annotation types are claimed and subsequent processors will not be asked to process them; if false is returned, the annotation types 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.

如果当前注解处理器已经处理了传递进来的注解，你不希望它们被传递给剩余其他注解处理器的话，返回true。
