compile
public boolean compile(int pass)

- Description copied from class:
NodeBase
- This method may be overwritten to perform compilation tasks (for example
optimization) on this node.
compile
will be called with a
parameter 0
directly after parsing the node, i.e. after
parsing all children. The invocation with bigger pass
parameters happens not before the whole transformation sheet has been
completely parsed.
- Overrides:
compile
in class NodeBase
- Parameters:
pass
- the number of invocations already performed on this node
- Returns:
true
if another invocation in the next pass is
necessary, false
if the compiling is complete.
This instance returns false
.
- Throws:
SAXException
process
public short process(Context context)
throws SAXException
- Evaluate the expression given in the test attribute and
adjust the next instruction depending on the result.
- Overrides:
process
in class NodeBase
- Returns:
Constants.PR_CONTINUE
- Throws:
SAXException
- if an error occurs (in a derived class)
