Package com.saxonica.functions.extfn Description

The package com.saxonica.extfn contains implementations of extension functions in the Saxon namespace.

It also contains the class ExtraFunctionLibrary which acts as a factory class for generating instances of these extension functions

Most of these classes are implemented using the new "integrated extension function" mechanism introduced in Saxon 9.2. A few still use the reflection mechanism, these are in class com.saxonica.extfn.Extensions.
