Class Iterator

Description

Wrapper for iterators that implements the 8.0 and earlier iterator API. This class doubles as the interface for old-style iterators.

The symbols required to be implemented in this API are:

• Check whether the iterator points to a valid item.

• Get the current iterator index.

• Get the current iterator value.

• Advance the iterator. One of them may be omitted. next() is preferred by foreach().

Deprecated

Replaced by Iterator.

Method create

Iterator Iterator(Iterator it)

Description

Initialize this iterator to wrap the Iterator in it

The iterator initially points to the first item in the data set, if there is any.

Note

This differs from the Iterator API, where the iterator is initialized to point before the first element.
