Method Detail

sort

public CacheQuery sort(org.apache.lucene.search.Sort sort)

Description copied from interface: CacheQuery

Allows lucene to sort the results. Integers are sorted in descending order.

Specified by:

sort in interface CacheQuery

Overrides:

sort in class CacheQueryImpl

Parameters:

sort - - lucene sort object

getResultSize

public int getResultSize()

Description copied from interface: CacheQuery

Gets the integer number of results.

Specified by:

getResultSize in interface CacheQuery

Overrides:

getResultSize in class CacheQueryImpl

Returns:

The result size of the query.

iterator

public QueryIterator iterator(int fetchSize)
                       throws org.hibernate.search.SearchException

Description copied from interface: CacheQuery

Returns the results of a search as a QueryIterator with a given integer parameter - the fetchSize.

Specified by:

iterator in interface CacheQuery

Overrides:

iterator in class CacheQueryImpl

Parameters:

fetchSize - integer to be given to the implementation constructor.

Returns:

a QueryResultIterator which can be used to iterate through the results that were found.

Throws:

org.hibernate.search.SearchException

lazyIterator

public QueryIterator lazyIterator(int fetchSize)

Description copied from interface: CacheQuery

Lazily loads the results from the Query as a QueryIterator with a given integer parameter - the fetchSize.

Specified by:

lazyIterator in interface CacheQuery

Overrides:

lazyIterator in class CacheQueryImpl

Parameters:

fetchSize - integer to be passed into the lazy implementation of QueryIterator

Returns:

a QueryResultIterator which can be used to lazily iterate through results.

list

public List<Object> list()
                  throws org.hibernate.search.SearchException

Description copied from interface: CacheQuery

Returns the results of a search as a list.

Specified by:

list in interface CacheQuery

Overrides:

list in class CacheQueryImpl

Returns:

list of objects that were found from the search.

Throws:

org.hibernate.search.SearchException
