ends, i.e.
|
void |
setVarStackPos(int top)
Set an index to the point in the variable stack where we should
begin variable searches for evaluation of expressions.

- Must be a non-null reference to an ElemVariable.sourceNode
- The node context for execution.transformer
- The transformer execution context.varStackPos

begin variable searches for evaluation of expressions.varStackContext
- An index into the variable stack where the variable context
ends, i.e. at the point we should terminate the search.isGlobal
- true if this is a global variable.public XObject execute(XPathContext xctxt) throws TransformerException

top
- A valid value that specifies where in the variable

bottom
- The point at which the search should terminate, normally
zero for global variables.public int getType()
