Method Detail

setFilter

public void setFilter(org.apache.lucene.search.Filter f)

Takes in a lucene filter and sets it to the filter field in the class.

Specified by:

setFilter in interface CacheQuery

Parameters:

f - - lucene filter

getResultSize

public int getResultSize()

Description copied from interface: CacheQuery

Gets the integer number of results.

Specified by:

getResultSize in interface CacheQuery

Returns:

The result size of the query.

setSort

public void setSort(org.apache.lucene.search.Sort s)

Description copied from interface: CacheQuery

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

Specified by:

setSort in interface CacheQuery

Parameters:

s - - lucene sort object

enableFullTextFilter

public org.hibernate.search.FullTextFilter enableFullTextFilter(String name)

Enable a given filter by its name.

Specified by:

enableFullTextFilter in interface CacheQuery

Parameters:

name - of filter.

Returns:

a FullTextFilter object.

disableFullTextFilter

public void disableFullTextFilter(String name)

Disable a given filter by its name.

Specified by:

disableFullTextFilter in interface CacheQuery

Parameters:

name - of filter.

setFirstResult

public void setFirstResult(int firstResult)

Sets the the result of the given integer value to the first result.

Specified by:

setFirstResult in interface CacheQuery

Parameters:

firstResult - index to be set.

Throws:

IllegalArgumentException - if the index given is less than zero.

iterator

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

Description copied from interface: CacheQuery

Returns the results of a search as a QueryIterator. This calls CacheQuery.iterator(int fetchSize) but uses a default fetchSize of 1.

Specified by:

iterator in interface Iterable

Specified by:

iterator in interface CacheQuery

Returns:

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

Throws:

org.hibernate.search.SearchException

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

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()

Description copied from interface: CacheQuery

Calls the CacheQuery.lazyIterator(int fetchSize) method but passes in a default 1 as a parameter.

Specified by:

lazyIterator in interface CacheQuery

Returns:

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

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

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

Returns:

list of objects that were found from the search.

Throws:

org.hibernate.search.SearchException

setMaxResults

public void setMaxResults(int maxResults)

Description copied from interface: CacheQuery

Sets the maximum number of results to the number passed in as a parameter.

Specified by:

setMaxResults in interface CacheQuery

Parameters:

maxResults - that are to be set to the maxResults.
