Map stream of Data into Page<T>

For quite a while now I am trying to get following to work in my resource / controller:

Have a stream of data and then map the stream of data to a Page response

Page<SomeType> controllerMethod() {

    List<SomeType> allItems = someRepository.findAll()
                              .filter(something)
                              .collect(Collectors.toList())

    return allItems.map(...?)
}

Question:

Are there any helpers from spring that can help me acheive this?

It would be ok that the paging is not done on DB level.

spring-data-jpa spring-boot spring

PageImpl has constructor from list

Page<SomeType> controllerMethod() {

    List<SomeType> allItems = someRepository.findAll()
                              .filter(something)
                              .collect(Collectors.toList())

    return new PageImpl<>(allItems);
}
