Interfaces
| Interface | Description | |
|---|---|---|
| nChannelConnectionListener | This interface should be implemented by classes wishing to register to receive callbacks when connections are added or removed to a nirvana channel | |
| nConnectionListener | This interface should be implemented by any object that wishes to handle disconnects and reconnects with the Nirvana server/s | |
| nDataGroupListener | The nDataGroupListener class is a Listener interface used to manage changes to membership of data groups | |
| nDataStreamListener | The nDataStreamListener class is used to receive events asynchronously from a data group | |
| nEventListener | This interface should be implemented by any object that wishes to register itself as a subscriber to a nirvana channel or queue | |
| nNamedPriorityListener | This interface should be implemented by any object that requires a callback when the subscription to a channel with a named object and priority enabled reaches the top. | |
| nRegisteredEventListener | This interface should be implemented by any object that wishes to register itself as an asynchronous subscriber and receive update events and complete merged events from a registered event Depreciated as of Version 6.0, use a standard nEventProperties merge if you wish to have complete messages. | |
| nRegisteredEventUpdateListener | This interface should be implemented by any object that wishes to register itself as an asynchronous subscriber and only receive update events only from a registered event Depreciated as of Version 6.0, use a standard nEventProperties merge if you wish to have complete messages. |
Classes
| Class | Description | |
|---|---|---|
| nChannel | This class is a Nirvana channel, offering the Nirvana channel related services it can only be made by calling the appropriate method in nSession | |
| nChannelAttributes | This class is a container for the attributes necessary to create or locate a Nirvana channel | |
| nChannelPublishKeys | This class contains the information about a single channel key. | |
| nConflationAttributes | This class represents the conflation attributes that can be used when creating resources which allow conflation. | |
| nConsumeEvent | This class represents a Nirvana event, which consists a tag and some data. | |
| nDataGroup | This class represents a individual data group object. | |
| nDataGroupIterator | Used to iterate through the nDataStreams contained within an nDataGroup | |
| nDataStream | The nDataStream class is a single instance of a data stream. | |
| nEventAttributes | The nEventAttributes class is used by the nConsumeEvent object in order to store standard header values associated with nirvana client, p2p and JMS events. | |
| nEventListenerHelper | This class is a helper class for the nEventListener class | |
| nEventProperties | This class contains a collection of key-value pairs, defining event meta data which can be used to create filter rules. | |
| nFindResult | This class represents the results of the nSession.find(nChannelAttributes[]) call. | |
| nNamedObject | This class represents a client context on a RealmServer. | |
| nProtobufEvent | This class is a Protocol Buffer event. | |
| nProtobufEventFactory | This class is used to create nProtobufEvent's. | |
| nQueue | This class is a Nirvana queue, offering the Nirvana queue related services it can only be made by calling the appropriate method in nSession | |
| nQueueAsynchronousTransactionalReader | This class extends the asynchronous queue model by adding the transactional ability to the reader. | |
| nQueueAttributes | This class is a container for the attributes necessary to create or locate a Nirvana queue | |
| nQueueDetails | Container class, containing statistics on the queue | |
| nQueueReader | This class is the base class for all Queue Readers and provides a generic reader interface. | |
| nQueueReaderContext | This class is used to construct a Queue Reader. | |
| nRegisteredEvent | This class enables a client to maintain a copy of an event, make changes to the properties and then when commit is called only the changes are published to the server. | |
| nSession | This class represents a Nirvana session, the logical connection between the client API and the Nirvana realm. | |
| nSessionAttributes | This class is a container for the attributes necessary to create a Nirvana session. | |
| nSessionFactory | This class is used with a nSessionAttributes object to create a Nirvana session. | |
| nStore | This is the base class of nChannel and nQueue, when ever a channel or queue is found it will be returned as this type. | |
| nStoreAttributes | This is the base class of nChannelAttributes and nQueueAttributes, it will be returned in most cases from the server it can then be cast to its derived classes To check which type it is call isChannel or isQueue to find out. | |
| nSubscriptionAttributes | This class represents the attributes used for channel subscriptions. | |
| nTransaction | This class enables the client to perform transactional publishing, representing a nirvana transaction | |
| nTransactionAttributes | This class is a container for the attributes necessary to create a Nirvana transaction | |
| nTransactionFactory | This class is used with a nTransactionAttributes object to create a Nirvana transaction. |
