Method Detail

foreach

public final void foreach(Consumer<E> consumer)

Description copied from interface: EnclosedIterable

Apply the sink to all elements in the Collection.

Specified by:

foreach in interface EnclosedIterable<E>

size

public final int size()

Specified by:

size in interface EnclosedIterable<E>

Specified by:

size in interface Sized

Returns:

the likely size of the objects passed into the sink in EnclosedIterable.foreach(Consumer). Be careful depending on this size being exact, as in many cases its best efforts value or may be unstable due to concurrent changes.

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface EnclosedIterable<E>

Specified by:

isEmpty in interface Sized

Returns:

true if the there is no data behind it.

createListIterator

protected abstract OfBizListIterator createListIterator()

Create a new iterator.

Returns:

an instance of OfBizListIterator
