Method Detail

### simplify

    public Expression simplify(StaticContext env)
                        throws XPathException

  Simplify: add a second implicit argument, the context document

  Specified by:
    `simplify` in interface `Expression`
  Overrides:
    `simplify` in class `FunctionCall`
  Throws:
    `XPathException`

### preEvaluate

    public Expression preEvaluate(StaticContext env)

  preEvaluate: this method suppresses compile-time evaluation by doing nothing

  Overrides:
    `preEvaluate` in class `FunctionCall`

### evaluateItem

    public Item evaluateItem(XPathContext context)
                      throws XPathException

  Evaluate the expression

  Specified by:
    `evaluateItem` in interface `Expression`
  Overrides:
    `evaluateItem` in class `ComputedExpression`
  Parameters:
    `context` - The context in which the expression is to be evaluated
  Returns:
    the node or atomic value that results from evaluating the expression; or null to indicate that the result is an empty sequence
  Throws:
    `XPathException` - if any dynamic error occurs evaluating the expression
