Class IteratorStatus

java.lang.Object
  org.apache.struts2.views.jsp.IteratorStatus

public class IteratorStatus
extends Object

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
