LoopTag (Jakarta Standard Tag Library API documentation)

All Superinterfaces:

jakarta.servlet.jsp.tagext.JspTag, jakarta.servlet.jsp.tagext.Tag

All Known Implementing Classes:

LoopTagSupport
```
public interface LoopTag
extends jakarta.servlet.jsp.tagext.Tag
```
The Jakarta Standard Tag Library allows developers to write custom iteration tags by implementing the LoopTag interface. This is not to be confused with jakarta.servlet.jsp.tagext.IterationTag as defined in Jakarta Server Pages 1.2. LoopTag establishes a mechanism for iteration tags to be recognized and for type-safe implicit collaboration with custom subtags.
In most cases, it will not be necessary to implement this interface manually, for a base support class (LoopTagSupport) is provided to facilitate implementation.

- Method Detail

Object getCurrent()

    Returns:
    
    the current item as an object
  - getLoopStatus
```
LoopTagStatus getLoopStatus()
```
    Retrieves a 'status' object to provide information about the current round of the iteration.
    
    Returns:
    
    The LoopTagStatus for the current LoopTag.
