Examples of org.pdf4j.saxon.functions.NumberFn

org.pdf4j.saxon.functions.NumberFn
Implements the XPath number() function. This can also be used as a mapping function in a MappingIterator to map a sequence of values to numbers.

        condition = new BooleanExpression(condition, Token.OR, isString);
        condition = new BooleanExpression(condition, Token.OR, isUntypedAtomic);
        condition = new BooleanExpression(condition, Token.OR, isBoolean);


        var = new LocalVariableReference(let);
        NumberFn fn = (NumberFn)SystemFunction.makeSystemFunction("number", new Expression[]{var});


        var = new LocalVariableReference(let);
        var.setStaticType(SequenceType.SINGLE_ATOMIC, null, 0);
        Expression action = Choose.makeConditional(condition, fn, var);
        let.setAction(action);
