Class LoopIterator
Object
dw.util.Iterator
dw.web.LoopIterator
Iterator used in <ISLOOP> implementation. It defines properties used to determine loop status. LoopIterator object is assigned to variable declared in "status" attribute of the <ISLOOP> tag.
Properties
begin  :  Number  (Read Only)
Return begin iteration index. By default begin index is 0.
count  :  Number  (Read Only)
Return iteration count, starting with 1.
end  :  Number  (Read Only)
Return end iteration index. By default end index equals 'length - 1', provided that length is determined. If length cannot be determined end index is -1.
even  :  boolean  (Read Only)
Identifies if count is an even value.
first  :  boolean  (Read Only)
Identifies if the iterator is positioned at first iteratable item.
index  :  Number  (Read Only)
Return iteration index, which is the position of the iterator in the underlying iteratable object. Index is 0-based and is calculated according the following formula: Index = (Count - 1) * Step.
last  :  boolean  (Read Only)
Identifies if the iterator is positioned at last iteratable item.
length  :  Number  (Read Only)
Return the length of the object. If length cannot be determined, -1 is returned.
odd  :  boolean  (Read Only)
Identifies if count is an odd value.
step  :  Number  (Read Only)
Return iterator step.
Constructor Summary
This class does not have a constructor, so you cannot create it directly.
