Expression | simplify(ExpressionVisitor visitor)
Simplify an expression. |
Expression | typeCheck(ExpressionVisitor visitor, ItemType contextItemType) |
Returns: the copy of the original expression
Parameters: offer The type of rewrite being offered
Throws: XPathException
Parameters: original the original subexpression replacement the replacement subexpression
Returns: true if the original subexpression is found
Parameters: visitor an expression visitor
Returns: the simplified expression
Throws: net.sf.saxon.trans.XPathException if an error is discovered during expression rewriting
