ResultSetResultIterable

public ResultSetResultIterable(RowMapper<T> mapper,
 StatementContext ctx,
 Supplier<ResultSet> resultSetSupplier)

Method Details

iterator

public ResultIterator<T> iterator()

Description copied from interface: ResultIterable

Stream all the rows of the result set out with an Iterator. The Iterator must be closed to release database resources.

Specified by:

iterator in interface Iterable<T>

Specified by:

iterator in interface ResultIterable<T>

Returns:

the results as a streaming Iterator

collectInto

public <R extends Collection<? super T>> R collectInto(Type containerType)

Description copied from interface: ResultIterable

Collect the results into a container type.

Specified by:

collectInto in interface ResultIterable<T>

Parameters:

containerType - A Type object that must describe a container type

Returns:

A new collection implementing the container type with all results inserted

collectIntoList

public List<T> collectIntoList()

Description copied from interface: ResultIterable

Returns results in a List. The implementation of the list can be changed by registering a Collector:

     jdbi.getConfig(JdbiCollectors.class).registerCollector(List.class, Collectors.toCollection(LinkedList::new));
 

or

     handle.registerCollector(List.class, Collectors.toCollection(LinkedList::new));
 

If no collector is registered, then this method behaves like ResultIterable.list().

Specified by:

collectIntoList in interface ResultIterable<T>

Returns:

results in a List

See Also:

• ResultIterable.list()
• ResultIterable.toCollection(Supplier)

collectIntoSet

public Set<T> collectIntoSet()

Description copied from interface: ResultIterable

Returns results in a Set. The implementation of the set can be changed by registering a Collector:

     jdbi.getConfig(JdbiCollectors.class).registerCollector(Set.class, Collectors.toCollection(LinkedHashSet::new));
 

or

     handle.registerCollector(Set.class, Collectors.toCollection(LinkedHashSet::new));
 

If no collector is registered, then this method behaves like ResultIterable.set().

Specified by:

collectIntoSet in interface ResultIterable<T>

Returns:

results in a Set

See Also:

• ResultIterable.set()
• ResultIterable.toCollection(Supplier)
