Method get_iterator()

Method get_iterator

Iterator get_iterator(object|array|mapping|multiset|string data)

Description

Creates and returns a canonical iterator for data.

Returns

data can have any of the following types:

object	If data is an object with lfun::_get_iterator defined then it's called in it to create the iterator. If data is an object that lacks lfun::_get_iterator then it's assumed to already be an iterator object, and is simply returned.
array	If data is an array, an Array.Iterator object will be returned.
mapping	If data is a mapping, a Mapping.Iterator object will be returned
multiset	If data is a multiset, a Multiset.Iterator object will be returned
string	If data is a string, a String.Iterator object will be returned

Note

This function is used by foreach to get an iterator for an object.
