- Description copied from interface:
Tag
- Evaluates this tag after all the tags properties have been initialized.
setItems
public void setItems(Expression items)
- Sets the expression used to iterate over.
This expression could resolve to an Iterator, Collection, Map, Array,
Enumeration or comma separated String.
setVar
public void setVar(java.lang.String var)
- Sets the variable name to export for the item being iterated over
setIndexVar
public void setIndexVar(java.lang.String indexVar)
- Sets the variable name to export the current index counter to
setBegin
public void setBegin(int begin)
- Sets the starting index value
setEnd
public void setEnd(int end)
- Sets the ending index value
setStep
public void setStep(int step)
- Sets the index increment step
setVarStatus
public void setVarStatus(java.lang.String var)
- Sets the variable name to export the current index to.
This does the same thing as #setIndexVar(), but is consistent
with the JSTL
syntax.
