This builder will be ordered first in the rule registration list. If the node has a jsfid attribute, and its value is "ignore", or "void" then special assumptions will be made. Beside the clay "ignore" and "void" directives, handles all "jsp:" nodes. Most are are assigned to the clay "void" directive except the "jsp:include" and "jsp:directive.include" elements. The include and directive.include are converted into a nested clay components.

Method Detail

execute

public boolean execute(Context context)
                throws Exception

If the node has a jsfid attribute, and its value is "ignore", child elements will be rendered as comment/verbatim content. The enclosing tag will not be rendered in the document, only it's children. If the jsfid is "void", the element will not be rendered but its children will keep their original characteristics.

All "jsp:" nodes are assigned to the clay void directive except the "jsp:include" and "jsp:directive.include". These are converted into a nested clay component. Nodes with a jsp prefix must be in the "http://java.sun.com/JSP/Page" namespace to be eligible for this processing.
