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 classSystemFunction
- Parameters:
visitor
- the expression visitorcontextInfo
- information about the context itemarguments
- 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
Evaluate the expression- Specified by:
call
in interfaceCallable
- Parameters:
context
- the dynamic evaluation contextarguments
- 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 modifiershasExplicitRadix
- 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
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 interfaceStatefulSystemFunction
- Returns:
- a copy of the system function able to contain its own copy of the state on behalf of the caller.
