findAll

public List<jakarta.persistence.Tuple> findAll(org.springframework.data.jpa.domain.Specification<T> specification,
 org.springframework.data.domain.Pageable pageable,
 BiFunction<jakarta.persistence.criteria.Root<T>,jakarta.persistence.criteria.CriteriaBuilder,List<jakarta.persistence.criteria.Selection<?>>> selectionsProvider)

selectionsProvider - callback that defines the tuple selections for the query

Returns:

tuples matching the requested filter, sort, and selection set

findAllPaged

public org.springframework.data.domain.Page<jakarta.persistence.Tuple> findAllPaged(org.springframework.data.jpa.domain.Specification<T> specification,
 org.springframework.data.domain.Pageable pageable,
 BiFunction<jakarta.persistence.criteria.Root<T>,jakarta.persistence.criteria.CriteriaBuilder,List<jakarta.persistence.criteria.Selection<?>>> selectionsProvider)

findAllPaged in interface WebQueryRepository<T>

Parameters:

specification - filtering criteria to apply

pageable - paging and sorting information; sorting is always applied and limits are applied when paged

selectionsProvider - callback that defines the tuple selections for the query
