InstanceStateKind Fields

Indicates that:

• Samples have been received for the instance
• There are live DataWriter entities writing the instance
• The instance has not been explicitly disposed (or else more samples have been received after it was disposed)

Indicates the instance was explicitly disposed by a DataWriter by means of the Delete operation.

Indicates the instance has been declared as not-alive by the DataReader because it detected that there are no live DataWriter entities writing that instance.
