Class 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.
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.
length
:
Number
(Read Only)
Return the length of the object. If length cannot be determined, -1 is returned.
step
:
Number
(Read Only)
Return iterator step.
Constructor Summary
This class does not have a constructor, so you cannot create it directly.
Method Summary
getIndex()
:
Number
Return iteration index, which is the position of the iterator in the underlying iteratable object.
isEven()
:
boolean
Identifies if count is an even value.
isFirst()
:
boolean
Identifies if the iterator is positioned at first iteratable item.
isLast()
:
boolean
Identifies if the iterator is positioned at last iteratable item.
isOdd()
:
boolean
Identifies if count is an odd value.
