Prior to this commit, searching for merged annotations on an
AnnotatedElement in the MergedAnnotations model was only supported via
various overloaded from(...) factory methods. In addition, it was not
possible to provide a custom AnnotationFilter without providing an
instance of RepeatableContainers.
This commit introduces a fluent API for searches in MergedAnnotations
to address these issues and improve the programming model for users of
MergedAnnotations.
To begin a search, invoke MergedAnnotations.search(SearchStrategy) with
the desired search strategy. Optional configuration can then be
provided via one of the with(...) methods. To perform a search, invoke
from(AnnotatedElement), supplying the element from which to begin the
search -- for example, a Class or a Method.
For example, the following performs a search on MyClass within the
entire type hierarchy of that class while ignoring repeatable
annotations.
MergedAnnotations mergedAnnotations =
MergedAnnotations.search(SearchStrategy.TYPE_HIERARCHY)
.withRepeatableContainers(RepeatableContainers.none())
.from(MyClass.class);
To reuse search configuration to perform the same type of search on
multiple elements, you can save the Search instance as demonstrated in
the following example.
Search search = MergedAnnotations.search(SearchStrategy.TYPE_HIERARCHY)
.withRepeatableContainers(RepeatableContainers.none());
MergedAnnotations mergedAnnotations = search.from(MyClass.class);
// do something with the MergedAnnotations for MyClass
mergedAnnotations = search.from(AnotherClass.class);
// do something with the MergedAnnotations for AnotherClass
In addition, this fluent search API paves the way for introducing
support for a predicate that controls the search on enclosing classes
(gh-28207) and subsequently for completely removing the
TYPE_HIERARCHY_AND_ENCLOSING_CLASSES search strategy (gh-28080).
Closes gh-28208
