```
public interface ReactivePanacheQuery<Entity extends Object>

                    
```
Interface representing an entity query, which abstracts the use of paging, getting the number of results, and operating on List or Stream.
Instances of this interface cannot mutate the query itself or its parameters: only paging information can be modified, and instances of this interface can be reused to obtain multiple pages of results.

Method Summary

Modifier and Type	Method	Description
`abstract <NewEntity extends Any> ReactivePanacheQuery<NewEntity>`	`project(Class<NewEntity> type)`	Defines a projection class: the getters, and the public fields, will be used to restrict which fields should be retrieved from the database.
`abstract ReactivePanacheQuery<Entity>`	`page(Page page)`	Sets the current page.
`abstract ReactivePanacheQuery<Entity>`	`page(Integer pageIndex, Integer pageSize)`	Sets the current page.
`abstract Page`	`page()`	Returns the current page.
`abstract ReactivePanacheQuery<Entity>`	`nextPage()`	Sets the current page to the next page
`abstract ReactivePanacheQuery<Entity>`	`previousPage()`	Sets the current page to the previous page (or the first page if there is no previous page)
`abstract ReactivePanacheQuery<Entity>`	`firstPage()`	Sets the current page to the first page
`abstract Uni<ReactivePanacheQuery<Entity>>`	`lastPage()`	Sets the current page to the last page.
`abstract Uni<Boolean>`	`hasNextPage()`	Returns true if there is another page to read after the current one.
`abstract Boolean`	`hasPreviousPage()`	Returns true if there is a page to read before the current one.
`abstract Uni<Integer>`	`pageCount()`	Returns the total number of pages to be read using the current page size.
`abstract ReactivePanacheQuery<Entity>`	`range(Integer startIndex, Integer lastIndex)`	Switch the query to use a fixed range (start index - last index) instead of a page.
`abstract ReactivePanacheQuery<Entity>`	`withCollation(Collation collation)`	Define the collation used for this query.
`abstract ReactivePanacheQuery<Entity>`	`withReadPreference(ReadPreference readPreference)`	Define the read preference used for this query.
`abstract Uni<Long>`	`count()`	Reads and caches the total number of entities this query operates on.
`abstract Uni<List<Entity>>`	`list()`	Returns the current page of results as a List.
`abstract Multi<Entity>`	`stream()`	Returns the current page of results as a Stream.
`abstract Uni<Entity>`	`firstResult()`	Returns the first result of the current page index.
`abstract Uni<Entity>`	`singleResult()`	Executes this query for the current page and return a single result.

```
 abstract <NewEntity extends Any> ReactivePanacheQuery<NewEntity> project(Class<NewEntity> 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
```
 abstract ReactivePanacheQuery<Entity> page(Page page)
```
    Sets the current page.
    
    Parameters:
    
    page - the new page
  - page
```
 abstract ReactivePanacheQuery<Entity> page(Integer pageIndex, Integer pageSize)
```
    Sets the current page.
    
    Parameters:
    
    pageIndex - the page index
    
    pageSize - the page size
  - page
```
 abstract Page page()
```
    Returns the current page.
  - nextPage
```
 abstract ReactivePanacheQuery<Entity> nextPage()
```
    Sets the current page to the next page
  - previousPage
```
 abstract ReactivePanacheQuery<Entity> previousPage()
```
    Sets the current page to the previous page (or the first page if there is no previous page)
  - firstPage
```
 abstract ReactivePanacheQuery<Entity> firstPage()
```
    Sets the current page to the first page
  - lastPage
```
 abstract Uni<ReactivePanacheQuery<Entity>> lastPage()
```
    Sets the current page to the last page. This will cause reading of the entity count.
  - hasNextPage
```
 abstract 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
```
 abstract Boolean hasPreviousPage()
```
    Returns true if there is a page to read before the current one.
  - pageCount
```
 abstract 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
```
 abstract 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
```
 abstract ReactivePanacheQuery<Entity> withCollation(Collation collation)
```
    Define the collation used for this query.
    
    Parameters:
    
    collation - the collation to be used for this query.
  - withReadPreference
```
 abstract 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
```
 abstract 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
```
 abstract Uni<List<Entity>> list()
```
    Returns the current page of results as a List.
  - stream
```
 abstract Multi<Entity> stream()
```
    Returns the current page of results as a Stream.
  - firstResult
```
 abstract Uni<Entity> firstResult()
```
    Returns the first result of the current page index. This ignores the current page size to fetch a single result.
  - singleResult
```
 abstract Uni<Entity> singleResult()
```
    Executes this query for the current page and return a single result.
