public ContextCollector(ContextProvider p)
                 throws JspTagException

Throws:

JspTagException

Method Detail

createBacking

protected BasicBacking createBacking(PageContext pc)

Overrides:

createBacking in class StandaloneContextContainer

unRegister

public void unRegister(String key)
                throws JspTagException

Overrides:

unRegister in class ContextContainer

Throws:

JspTagException

register

protected void register(String newid,
                        Object n,
                        boolean check,
                        boolean checkParent)
                 throws JspTagException

Overrides:

register in class ContextContainer

Throws:

JspTagException

doAfterBody

public final void doAfterBody(boolean iteratesAgain)
                       throws JspTagException

For a context-collector it also interesting to have a 'doAFterBody', because it can be iterated again. It calls ContextContainer.clear().

Throws:

JspTagException

release

public void release(PageContext pc,
                    ContextContainer p)

Overrides:

release in class StandaloneContextContainer
