> The bitfield field is set to true for every field after deserialization of a
> Thrift message structure.
> Here is a simple test program :
> {code:java}
> public class BitFieldTest
> {
> public static void main(String[] args) throws TException
> {
> final CBChannel chan = new CBChannel();
> chan.setId(42L);
> chan.setName("test");
> // should return true, true, false
> System.out.println("id is set ? " + chan.isSetId());
> System.out.println("name is set ? " + chan.isSetName());
> System.out.println("duration max is set ? " +
> chan.isSetDurationMax());
> final TProtocolFactory protoFactory = new
> TCompactProtocol.Factory();
> final byte[] buf = new
> TSerializer(protoFactory).serialize(chan);
> System.out.println("\n---- Hexdump serialized message : ----\n"
> + HexTools.toHexString(buf));
> final CBChannel chanDst = new CBChannel();
> new TDeserializer(protoFactory).deserialize(chanDst, buf);
> System.out.println("---- toString() of deserialized api msg :
> ----\n" + chanDst);
> // should return true, true, false
> System.out.println("\nid is set ? " + chanDst.isSetId());
> System.out.println("name is set ? " + chanDst.isSetName());
> System.out.println("duration max is set ? " +
> chanDst.isSetDurationMax());
> }
> }
> {code}
> The output is :
> {noformat}
> id is set ? true
> name is set ? true
> duration max is set ? false
> ---- Hexdump serialized message : ----
> 00 16 54 18 04 74 65 73 74 12 26 00 16 00 16 00 16 .T..test.&......
> 10 00 16 00 16 00 16 00 00 ........
> ---- toString() of deserialized api msg : ----
> CBChannel(id:42, name:test, enabled:false, type:null, durationMin:0,
> durationMax:0, inactivityAlarm:0, analogicConfiguration:0,
> digitalConfiguration:0, voipConfiguration:0, r17Index:0, group:null)
> id is set ? true
> name is set ? true
> duration max is set ? true
> {noformat}
> You can see that the last test for is set on the durationMax field return
> true, when it sould return false.
> Here is the idl file :
> {code:java}
> enum ChannelType
> {
> ANALOGIC
> DIGITAL
> VOIP
> }
> struct CBChannelGroup
> {
> 1: i64 id;
> 2: i64 parentId;
> 3: string name;
> }
> struct CBChannel
> {
> 1: i64 id;
> 2: string name;
> 3: bool enabled;
> 4: ChannelType type;
> 5: i64 durationMin;
> 6: i64 durationMax;
> 7: i64 inactivityAlarm;
> 8: i64 analogicConfiguration;
> 9: i64 digitalConfiguration;
> 10: i64 voipConfiguration;
> 11: i64 r17Index;
> 12: CBChannelGroup group;
> }
> {code}
