Interface
zope.tales.interfaces.ITALESIterator

TAL Iterator provided by TALES

Values of this iterator are assigned to items in the repeat namespace.

For example, with a TAL statement like: tal:repeat="item items", an iterator will be assigned to "repeat/item". The iterator provides a number of handy methods useful in writing TAL loops.

The results are undefined of calling any of the methods except length before the first iteration.
