| WrappedIterator | | public class WrappedIterator extends NiceIterator (Code) | | a WrappedIterator is an ExtendedIterator wrapping around a plain (or
presented as plain) Iterator. The wrapping allows the usual extended
operations (filtering, concatenating) to be done on an Iterator derived
from some other source.

| Field Summary | |
| final protected Iterator | base
| | protected boolean | removeDenied
set to true if this wrapping doesn't permit the use of
.remove(). |
| base | | final protected Iterator base(Code) | | the base iterator that we wrap
|
| removeDenied | | protected boolean removeDenied(Code) | | set to true if this wrapping doesn't permit the use of
.remove(). Otherwise the .remove() is delegated to the base iterator.
|
| WrappedIterator | | protected WrappedIterator(Iterator base)(Code) | | constructor: remember the base iterator
|
| WrappedIterator | | protected WrappedIterator(Iterator base, boolean removeDenied)(Code) | | Initialise this wrapping with the given base iterator and remove-control.
Parameters:
base - the base iterator that this tierator wraps
Parameters:
removeDenied - true if .remove() must throw an exception |
| close | | public void close()(Code) | | close: defer to the base, iff it is closable
|
| close | | public static void close(Iterator it)(Code) | | if it is a Closableiterator, close it. Abstracts away from
tests [that were] scattered through the code.
|
| create | | public static ExtendedIterator create(Iterator it)(Code) | | Answer an ExtendedIterator returning the elements of it.
If it is itself an ExtendedIterator, return that; otherwise
wrap it.
|
| createNoRemove | | public static WrappedIterator createNoRemove(Iterator it)(Code) | | Answer an ExtendedIterator wrapped round it which does not
permit .remove() even if it does.
|
| hasNext | | public boolean hasNext()(Code) | | hasNext: defer to the base iterator
|
| next | | public Object next()(Code) | | next: defer to the base iterator
|
| remove | | public void remove()(Code) | | if .remove() is allowed, delegate to the base iterator's .remove;
otherwise, throw an UnsupportedOperationException.
