Method Detail

getEntityDescriptor

EntityDescriptor getEntityDescriptor()

Returns:

never null

endingIterator

Iterator<Object> endingIterator()

If Selector.isNeverEnding() is true, then Iterable.iterator() will never end. This returns an ending Iterator, that tries to match Iterable.iterator() as much as possible, but returns each distinct element only once and returns every element that might possibly be selected and therefore it might not respect the configuration of this EntitySelector entirely.

Returns:

never null
