javax.servlet.jsp.jstl.core: public interface: LoopTag

javax.servlet.jsp.jstl.core
public interface: LoopTag [javadoc | source]

All Implemented Interfaces:
Tag

All Known Implementing Classes:
LoopTagSupport

JSTL allows developers to write custom iteration tags by implementing the LoopTag interface. This is not to be confused with javax.servlet.jsp.tagext.IterationTag as defined in JSP 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 from javax.servlet.jsp.jstl.core.LoopTag Summary:
getCurrent, getLoopStatus

Method from javax.servlet.jsp.jstl.core.LoopTag Detail:
public Object getCurrent() Retrieves the current item in the iteration. Behaves idempotently; calling getCurrent() repeatedly should return the same Object until the iteration is advanced. (Specifically, calling getCurrent() does not advance the iteration.)
public LoopTagStatus getLoopStatus() Retrieves a 'status' object to provide information about the current round of the iteration.
