Purpose of the PR
The main purpose of this PR is to speed up the
AnnotatedMethod.hasRequiredMarkermethod.On getting a
RequiredMarkerfrom aKPropertyThe process of getting
RequiredMarkerfromKPropertyhas been modified to be done in a single loop.In the current implementation, the process of getting the
RequiredMarkerfromKPropertyis performed separately byAnnotatedMethod.getCorrespondingGetterandAnnotatedMethod.getCorrespondingSetter.member.declaringClass.kotlin.declaredMemberProperties, which is called in each of these two methods, is considered to be expensive to execute (I didn't run a benchmark to confirm this, but it seems so from the implementation).Therefore, reducing the number of calls to it will speed up the process.
Regarding
KFunction<*>.isSetterLike()Since the result of
Unit::class.createType()executed byKFunction<*>.isSetterLike()is immutable, it has been modified to be used as a constant.This process also seems to have been expensive to execute.
Others
I also did some refactoring at the same time.
Questions
Should
declaringClass.kotlin.declaredMemberPropertiesalso be cached asClass->List<KProperty1>?When serializing/deserializing a class with a large number of fields, it seems to be more efficient to cache this process as well.
