| ClassFunctions | | public class ClassFunctions implements Functions(Code) | | Extension functions provided by a Java class.
Let's say, we declared a ClassFunction like this:
new ClassFunctions(Integer.class, "int")
We can now use XPaths like:
"int:new(3)"- Equivalent to
new Integer(3)
"int:getInteger('foo')"- Equivalent to
Integer.getInteger("foo")
"int:floatValue(int:new(4))"- Equivalent to
new Integer(4).floatValue()
If the first argument of a method is ExpressionContext, the
expression context in which the function is evaluated is passed to
the method.
