public class PublicStylesheetFunctionLibrary extends Object implements FunctionLibrary
| Constructor and Description |
|---|
PublicStylesheetFunctionLibrary(FunctionLibrary base)
Create a FunctionLibrary that provides access to public stylesheet functions
|
| Modifier and Type | Method and Description |
|---|---|
Expression |
bind(SymbolicName.F functionName,
Expression[] staticArgs,
StaticContext env,
List<String> reasons)
Bind a function, given the URI and local parts of the function name,
and the list of expressions supplied as arguments.

FunctionLibrary |
copy()
This method creates a copy of a FunctionLibrary: if the original FunctionLibrary allows
new functions to be added, then additions to this copy will not affect the original, or
vice versa.

boolean |
isAvailable(SymbolicName.F functionName)
Test whether a function with a given name and arity is available

bind in interface FunctionLibraryfunctionName - The name of the functionstaticArgs - The expressions supplied statically in the function call. The intention is
that the static type of the arguments (obtainable via getItemType() and getCardinality() may
be used as part of the binding algorithm.env - The static contextreasons - If no matching function is found by the function library, it may add
a diagnostic explanation to this list explaining why none of the available
functions could be used.XPathException - if a function is found with the required name and arity, but
the implementation of the function cannot be loaded or used; or if an error occurs
while searching for the function; or if this function library "owns" the namespace containing
the function call, but no function was found.public boolean isAvailable(SymbolicName.F functionName)
This supports the function-available() function in XSLT.
