Examples of IteratorGeneratorTag

org.apache.struts2.views.jsp.iterator.IteratorGeneratorTag
NOTE: JSP-TAG
Generate an iterator based on the val attribute supplied.
NOTE: The generated iterator will ALWAYS be pushed into the top of the stack, and poped at the end of the tag.
- val* (Object) - the source to be parsed into an iterator
- count (Object) - the max number (Integer, Float, Double, Long, String) entries to be in the iterator
- separator (String) - the separator to be used in separating the val into entries of the iterator
- var (String) - the name to store the resultant iterator into page context, if such name is supplied
- converter (Object) - the converter (must extends off IteratorGenerator.Converter interface) to convert the String entry parsed from val into an object
Example One:
```
 Generate a simple iterator <s:generator val="%{'aaa,bbb,ccc,ddd,eee'}"> <s:iterator> <s:property /><br/> </s:iterator> </s:generator> 
```
This generates an iterator and print it out using the iterator tag. Example Two:
```
 Generate an iterator with count attribute <s:generator val="%{'aaa,bbb,ccc,ddd,eee'}" count="3"> <s:iterator> <s:property /><br/> </s:iterator> </s:generator> 
```
This generates an iterator, but only 3 entries will be available in the iterator generated, namely aaa, bbb and ccc respectively because count attribute is set to 3 Example Three:
```
 Generate an iterator with var attribute <s:generator val="%{'aaa,bbb,ccc,ddd,eee'}" count="4" separator="," var="myAtt" /> <% Iterator i = (Iterator) pageContext.getAttribute("myAtt"); while(i.hasNext()) { String s = (String) i.next(); %> <%=s%> <br/> <%    } %> 
```
This generates an iterator and put it in the PageContext under the key as specified by the var attribute. Example Four:
```
 Generate an iterator with comparator attribute <s:generator val="%{'aaa,bbb,ccc,ddd,eee'}" converter="%{myConverter}"> <s:iterator> <s:property /><br/> </s:iterator> </s:generator> public class GeneratorTagAction extends ActionSupport { .... public Converter getMyConverter() { return new Converter() { public Object convert(String value) throws Exception { return "converter-"+value; } }; } ... } 
```
This will generate an iterator with each entries decided by the converter supplied. With this converter, it simply add "converter-" to each entries. @see org.apache.struts2.util.IteratorGenerator
