Examples with ExtensionFunctionCall net.sf.saxon.lib.ExtensionFunctionCall used on opensource projects

Example 1 with ExtensionFunctionCall

use of net.sf.saxon.lib.ExtensionFunctionCall in project camel by apache.

the class MyExtensionFunction1 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)
            Int64Value arg1 = (Int64Value) arguments[0].iterate().next();
            int arg1Int = arg1.getDecimalValue().toBigInteger().intValue();
            // 2nd argument (mandatory, index 1)
            Int64Value arg2 = (Int64Value) arguments[1].iterate().next();
            int arg2Int = arg2.getDecimalValue().toBigInteger().intValue();
            // Functionality goes here
            int resultInt = arg1Int + arg2Int;
            Item result = new Int64Value(resultInt);
            return SequenceTool.toLazySequence(SingletonIterator.makeIterator(result));
        }
    };
