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 predef::Iterator.

Method create

Iterator Iterator(predef::Iterator it)

Description

Initialize this iterator to wrap the predef::Iterator in it

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

Note

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