- Method Detail
  - allocateArgumentEvaluators
```
protected void allocateArgumentEvaluators(FunctionCall expr,
                                          boolean allowRepeatedUse)
```
    Allocate evaluation functions for each argument (in field argumentEvaluators)
    
    Parameters:
    
    expr - the function call
    
    allowRepeatedUse - true if the value of the argument must be supplied to the function in a way that allows repeated use. This will be true for user-written functions, false for system functions, where the implementation is arranged to only use the value once.
  - evaluateArguments
```
protected Sequence[] evaluateArguments(XPathContext context)
                                throws XPathException
```
    Throws:
    
    XPathException
