Constructor Detail

ProcessBase

public ProcessBase(String qName,
                   NodeBase parent,
                   ParseContext context,
                   String groupQName,
                   String method,
                   String src)
            throws SAXParseException
Method Detail

insert

public void insert(NodeBase node)
            throws SAXParseException
Ensure that only stx:with-param children will be inserted

Overrides:
insert in class NodeBase
Parameters:
node - the node to be inserted
Throws:
SAXParseException

compile

public boolean compile(int pass)
                throws SAXException
Determine target group

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
assign target group, save and reset parameters

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

getProcessHandler

protected TransformerHandler getProcessHandler(Context context)
                                        throws SAXException
Returns a handler that performs a transformation according to the specified filter value.

Throws:
SAXException - if this handler couldn't be created
