Method Detail

• project

   <T extends Any> ReactivePanacheQuery<T> project(Class<T> type)

  Defines a projection class: the getters, and the public fields, will be used to restrict which fields should be retrieved from the database.

• page

   ReactivePanacheQuery<Entity> page(Page page)

  Sets the current page.

  Parameters:

  page - the new page

• page

   ReactivePanacheQuery<Entity> page(Integer pageIndex, Integer pageSize)

  Sets the current page.

  Parameters:

  pageIndex - the page index

  pageSize - the page size

• page

   Page page()

  Returns the current page.

• nextPage

   ReactivePanacheQuery<Entity> nextPage()

  Sets the current page to the next page

• previousPage

   ReactivePanacheQuery<Entity> previousPage()

  Sets the current page to the previous page (or the first page if there is no previous page)

• firstPage

   ReactivePanacheQuery<Entity> firstPage()

  Sets the current page to the first page

• lastPage

   Uni<ReactivePanacheQuery<Entity>> lastPage()

  Sets the current page to the last page. This will cause reading of the entity count.

• hasNextPage

   Uni<Boolean> hasNextPage()

  Returns true if there is another page to read after the current one. This will cause reading of the entity count.

• hasPreviousPage

   Boolean hasPreviousPage()

  Returns true if there is a page to read before the current one.

• pageCount

   Uni<Integer> pageCount()

  Returns the total number of pages to be read using the current page size. This will cause reading of the entity count.

• range

   ReactivePanacheQuery<Entity> range(Integer startIndex, Integer lastIndex)

  Switch the query to use a fixed range (start index - last index) instead of a page. As the range is fixed, subsequent pagination of the query is not possible.

  Parameters:

  startIndex - the index of the first element, starting at 0

  lastIndex - the index of the last element

• withCollation

   ReactivePanacheQuery<Entity> withCollation(Collation collation)

  Define the collation used for this query.

  Parameters:

  collation - the collation to be used for this query.

• withReadPreference

   ReactivePanacheQuery<Entity> withReadPreference(ReadPreference readPreference)

  Define the read preference used for this query.

  Parameters:

  readPreference - the read preference to be used for this query.

• count

   Uni<Long> count()

  Reads and caches the total number of entities this query operates on. This causes a database query with SELECT COUNT(*) and a query equivalent to the current query, minus ordering.

• list

   Uni<List<Entity>> list()

  Returns the current page of results as a List.

• stream

   Multi<Entity> stream()

  Returns the current page of results as a Stream.

• firstResult

   Uni<Entity> firstResult()

  Returns the first result of the current page index. This ignores the current page size to fetch a single result.

• singleResult

   Uni<Entity> singleResult()

  Executes this query for the current page and return a single result.
