    <table><tr wicket:id="myTable">
      <wicket:param rowsPerPage=10/>
      ...
    </tr></table>

Constructor Detail

WicketParamTagHandler

public WicketParamTagHandler(IMarkupFilter parent)

Construct.

Method Detail

setStripWicketTag

public void setStripWicketTag(boolean strip)

Enable/disable removing Wicket param tags

Parameters:

strip - True, if Wicket param tags shall be removed

nextTag

public final MarkupElement nextTag()
                            throws java.text.ParseException

Get the next tags from the next MarkupFilter in the chain. Identify wicket param tags and handle them as described above.

Note: IXmlPullParser which is the last element in the chain returns XmlTag objects which are derived from MarkupElement. WicketParamTagHandler hwoever assumes that the next MarkupFilter in the chain returns either ComponentTags or ComponentWicketTags. Both are subclasses of MarkupElement as well. Thus, WicketParamTagHandler can not be the first MarkupFilter immediately following the IXmlPullParser. Some inline filter converting XmlTags into ComponentTags must preceed it.

Returns:

The next MarkupElement from markup. If null, no more tags are available

Throws:

java.text.ParseException
