Method Detail

### analyze

    public Expression analyze(StaticContext env,
                              ItemType contextItemType)
                       throws XPathException

  Description copied from class: `FunctionCall`
  Type-check the expression. This also calls preEvaluate() to evaluate the function if all the arguments are constant; functions that do not require this behavior can override the preEvaluate method.

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

### preEvaluate

    public Expression preEvaluate(StaticContext env)
                           throws XPathException

  preEvaluate: called if the argument is constant

  Overrides:
    `preEvaluate` in class `CompileTimeFunction`
  Throws:
    `XPathException`
