compile
public boolean compile(int pass,
ParseContext context)
throws SAXException
- Assign
trueNext
and falseNext
- Overrides:
compile
in class NodeBase
- Parameters:
pass
- the number of invocations already performed on this nodecontext
- the parse context
- Returns:
true
if another invocation in the next pass is
necessary, false
if the compiling is complete.
This instance returns false
.

Constants.PR_CONTINUE
- Throws:
SAXException
- if an error occurs (in a derived class)
