Method Details

resetQuery

public void resetQuery()

Overrides:

resetQuery in class BaseEmbeddedQuery<T>

recordQuery

protected void recordQuery(long time)

Specified by:

recordQuery in class BaseEmbeddedQuery<T>

getComparator

protected Comparator<Comparable<?>[]> getComparator()

Description copied from class: BaseEmbeddedQuery

Create a comparator to be used for ordering the results returned by BaseEmbeddedQuery.getInternalIterator().

Specified by:

getComparator in class BaseEmbeddedQuery<T>

Returns:

the comparator or null if no sorting needs to be applied

getInternalIterator

protected org.infinispan.commons.util.CloseableIterator<org.infinispan.objectfilter.ObjectFilter.FilterResult> getInternalIterator()

Description copied from class: BaseEmbeddedQuery

Create an iterator over the results of the query, in no particular order. Ordering will be provided if BaseEmbeddedQuery.getComparator() returns a non-null Comparator. Please note this it not the same iterator as the one retuend by BaseEmbeddedQuery.iterator().

Specified by:

getInternalIterator in class BaseEmbeddedQuery<T>

execute

public org.infinispan.query.dsl.QueryResult<T> execute()

Specified by:

execute in interface org.infinispan.query.dsl.Query<T>

Overrides:

execute in class BaseEmbeddedQuery<T>

executeStatement

public int executeStatement()

Specified by:

executeStatement in interface org.infinispan.query.dsl.Query<T>

Overrides:

executeStatement in class org.infinispan.query.dsl.impl.BaseQuery<T>

toString

public String toString()

Overrides:

toString in class BaseEmbeddedQuery<T>
