Method Detail

process

public short process(Context context)
              throws SAXException
Evaluate the select attribute if present.

Overrides:
process in class NodeBase
Parameters:
context - the current context
Returns:
Constants.PR_CONTINUE
Throws:
SAXException - if an error occurs (in a derived class)

processEnd

public short processEnd(Context context)
                 throws SAXException
Called only if this instruction has no select attribute. Evaluates its contents.

Overrides:
processEnd in class NodeBase
Parameters:
context - the current context
Returns:
Constants.PR_CONTINUE
Throws:
SAXException - if an error occurs (in a derived class)

processVar

private void processVar(Value v,
                        Context context)
                 throws SAXException
Assigns a value to a variable.

Parameters:
v - the value
context - the current context
Throws:
SAXException

onDeepCopy

protected void onDeepCopy(AbstractInstruction copy,
                          HashMap copies)
Description copied from class: AbstractInstruction
Callback that will be called when a clone of this instance has been created. To be overridden in subclasses.

Overrides:
onDeepCopy in class NodeBase
Parameters:
copy - the created clones
copies - the map of already copied objects
