> 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;
> }
