makeOptimizedFunctionCall

public Expression makeOptimizedFunctionCall(ExpressionVisitor visitor,
                                            ContextItemStaticInfo contextInfo,
                                            Expression... arguments)
                                     throws XPathException

Description copied from class: SystemFunction

Allow the function to create an optimized call based on the values of the actual arguments

Overrides:

makeOptimizedFunctionCall in class SystemFunction

Parameters:

visitor - the expression visitor

contextInfo - information about the context item

arguments - the supplied arguments to the function call. Note: modifying the contents of this array should not be attempted, it is likely to have no effect.

Returns:

either a function call on this function, or an expression that delivers the same result, or null indicating that no optimization has taken place

Throws:

XPathException - if an error is detected

call

public StringValue call(XPathContext context,
                        Sequence[] arguments)
                 throws XPathException

Evaluate the expression

Specified by:

call in interface Callable

Parameters:

context - the dynamic evaluation context

arguments - the values of the arguments, supplied as SequenceIterators

Returns:

the result of the evaluation, in the form of a SequenceIterator

Throws:

XPathException - if a dynamic error occurs during the evaluation of the expression

getPicSeparators

public static NumericGroupFormatter getPicSeparators(UnicodeString picExpanded,
                                                     boolean hasExplicitRadix)
                                              throws XPathException

Get the picture separators and filter them out of the picture. Has side effect of creating a simplified picture, which it makes available as the getAdjustedPicture() property of the returned NumericGroupFormatter.

Parameters:

picExpanded - the formatting picture, after stripping off any modifiers

hasExplicitRadix - true if digits are indicated by X or x rather than a decimal digit

Returns:

a NumericGroupFormatter that implements the formatting defined in the picture

Throws:

XPathException - if the picture is invalid

copy

public SystemFunction copy()

Description copied from interface: StatefulSystemFunction

Make a copy of this SystemFunction. This is required only for system functions such as regex functions that maintain state on behalf of a particular caller.

Specified by:

copy in interface StatefulSystemFunction

Returns:

a copy of the system function able to contain its own copy of the state on behalf of the caller.
