org.apache.olingo.odata2.api.uri.expression.LiteralExpression
Represents a literal expression node in the expression tree

A literal expression node is inserted in the expression tree for any token witch is no valid operator, method or property.

For example the filter "$filter=age eq 12" will result in an expression tree with a literal expression node for "12".

        final TestOlingo2ResponseHandler<ServiceDocument> responseHandler =
            new TestOlingo2ResponseHandler<ServiceDocument>();


        olingoApp.read(null, "", null, responseHandler);


        final ServiceDocument serviceDocument = responseHandler.await();
        final List<Collection> collections = serviceDocument.getAtomInfo().getWorkspaces().get(0).getCollections();
        assertEquals("Service Atom Collections", 3, collections.size());
        LOG.info("Service Atom Collections:  {}", collections);


        final List<EdmEntitySetInfo> entitySetsInfo = serviceDocument.getEntitySetsInfo();
        assertEquals("Service Entity Sets", 3, entitySetsInfo.size());
        LOG.info("Service Document Entries:  {}", entitySetsInfo);
