hidden abstract class %Library.Iterator extends %Base

%Library.Iterator defines a standard interface for iterators. It is compatible with legacy iterators that extend %Iterator.AbstractIterator.

This interface supports three common code patterns.

set array = [0,1,2,3,4]
set iterator = array.iterator()
while iterator.hasNext() {
    set next = iterator.next()
    // do something with next.key and next.value
}

set array = [0,1,2,3,4]
set iterator = array.iterator()
for {
    set next = iterator.next()
    quit:next=""
    // do something with next.key and next.value
}

set array = [0,1,2,3,4]
set iterator = array.iterator()
for {
    quit:'iterator.%GetNext(.key,.value)
    // do something with key and value
}

Implementors are expected to override next. %GetNext is present for compatibility with %Iterator.AbstractIterator
