Method Detail

compile

public boolean compile(int pass,
                       ParseContext context)
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
context - the parse context
Returns:
true if another invocation in the next pass is necessary, false if the compiling is complete. This instance returns false.

process

public short process(Context context)
              throws SAXException
Description copied from class: NodeBase
Save local variables if needed.

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
Description copied from class: NodeBase
Called when the end tag will be processed. This instance removes local variables declared in this node.

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

processParam

public void processParam(Value v,
                         Context context)
                  throws SAXException
Declare a parameter

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
