Examples with RecordClass org.apache.directory.server.dns.messages.RecordClass used on opensource projects

Example 1 with RecordClass

use of org.apache.directory.server.dns.messages.RecordClass in project vert.x by eclipse.

the class HostnameResolutionTest method testAddressSelection.

private void testAddressSelection(AddressResolverOptions options, int expected) throws Exception {
    Function<String, ResourceRecord> createRecord = ipAddress -> new ResourceRecord() {

        @Override
