Examples of org.apache.struts2.views.jsp.IteratorStatus

org.apache.struts2.views.jsp.IteratorStatus
The iterator tag can export an IteratorStatus object so that one can get information about the status of the iteration, such as:
- index: current iteration index, starts on 0 and increments in one on every iteration
- count: iterations so far, starts on 1. count is always index + 1
- first: true if index == 0
- even: true if (index + 1) % 2 == 0
- last: true if current iteration is the last iteration
- odd: true if (index + 1) % 2 == 1
Example
```
 <s:iterator status="status" value='{0, 1}'> Index: <s:property value="%{#status.index}" /> <br /> Count: <s:property value="%{#status.count}" /> <br />   </s:iterator> 
```
will print
```
 Index: 0 Count: 1 Index: 1 Count: 2 
```
