Example 1 with StringValue

use of net.sf.saxon.value.StringValue in project camel by apache.

the class MyExtensionFunction2 method makeCallExpression.

@Override
public ExtensionFunctionCall makeCallExpression() {
    return new ExtensionFunctionCall() {

        private static final long serialVersionUID = 1L;

        @Override
        public Sequence call(XPathContext xPathContext, Sequence[] arguments) throws XPathException {
            // 1st argument (mandatory, index 0)
            StringValue arg1 = (StringValue) arguments[0].iterate().next();
            String arg1Str = arg1.getStringValue();
            // 2nd argument (optional, index 1)
            String arg2Str = "";
            if (arguments.length > 1) {
                StringValue arg2 = (StringValue) arguments[1].iterate().next();
                arg2Str = arg2.getStringValue();
            }
            // Functionality goes here
            String resultStr = arg1Str + arg2Str;
            Item result = new StringValue(resultStr);
            return SequenceTool.toLazySequence(SingletonIterator.makeIterator(result));
        }
    };
