Classes
| CancellationToken |
A CancellationToken is used to propagate notification that operations should be canceled. You create a cancellation token by instantiating a CancellationTokenSource object, which manages cancellation tokens retrieved from its getToken() method. You then pass the cancellation token to any number of operations that should receive notice of cancellation. The token cannot be used to initiate cancellation. When the owning object calls cancel(), the cancelled property on the cancellation token is set to true. The objects that receive the notification can respond in whatever manner is appropriate. |
|
| CancellationTokenSource |
A CancellationTokenSource is used to create CancellationToken object and manage it. |
|
| ClaimsCredentials |
Represents the claim based security credential acquired from STS (security token service). |
|
| CodePackage |
Represents the code package definition. |
|
| ConfigurationPackage |
Represents a configuration package. |
|
| DataPackage |
Defines a data package of an application. |
|
| EncryptionUtility |
Utility class to perform encryption and decryption operations. |
|
| Epoch |
Represents the current version of the partition in Service Fabric.
Remarks:An Epoch is a configuration number for the partition as a whole. When the configuration of the replica set changes, for example when the Primary replica changes, the operations that are replicated from the new Primary replica are said to be a new Epoch from the ones which were sent by the old Primary replica. The fact that the Primary has changed is not directly visible to Secondary replicas, which are usually unaffected by the failure that affected the original Primary replica. To track that the Primary replica has changed has to be communicated to the Secondary replica. This communication occurs via the updateEpochAsync(Epoch epoch, SequenceNumber previousEpochLastSequenceNumber, CancellationToken cancellationToken) method. Most services can ignore the details of the inner fields of the Epoch as it is usually sufficient to know that the Epoch has changed and to compare Epochs to determine relative ordering of operations and events in the system. Comparison operations are provided for this purpose. |
|
| FabricClient |
Client for a Service Fabric cluster.
Remarks:It is highly recommended that you share FabricClients as much as possible. This is because the FabricClient has multiple optimizations such as caching and batching that you would not be able to fully utilize otherwise. |
|
| FabricClientSettings |
Represents the configuration settings for the FabricClient class. |
|
| FabricCodePackageActivationContext |
Represents activation context for the Service Fabric service. This is valid for fabric activated service only. |

Remarks:Provides the default implementation of the StateReplicator, Replicator, and PrimaryReplicator interfaces, which user services can use, along with their implementation of the StateProvider interface. An instance of the system.fabric.FabricReplicator class is obtained via the createReplicator(StateProvider stateProvider, ReplicatorSettings replicatorSettings) method, which can be cast to StateReplicator for use. |
|

They contain the replicateAsync(OperationData operationData, SequenceNumber sequenceNumber, CancellationToken cancellationToken) and the sequence number and other identifying information. |
|
| OperationDataStream |
An system.fabric.OperationDataStream encapsulates a stream of OperationData objects that are exchanged between Primary replica and Secondary replica. Objects that implement system.fabric.OperationDataStream are used during the copy process. Both the copy context getCopyContext() method that is sent from the Secondary replica to the Primary replica and the copy state getCopyState(SequenceNumber upToSequenceNumber, OperationDataStream copyContext) method implement the system.fabric.OperationDataStream interface. |
|
| OperationStream |
Represents a stream of replication or copy operations that are sent from the Primary to the Secondary replica.
Remarks: The streams returned from getCopyStream() and getReplicationStream() are objects that implement system.fabric.OperationStream. |

|
| StatefulServiceFactory |
Represents a stateful service factory that is responsible for creating replicas of a specific type of stateful service. Stateful service factories are registered with the FabricRuntime by service hosts via system.fabric.FabricRuntime#registerStatefulServiceFactory(java.lang.String,system.fabric.StatefulServiceFactory) or system.fabric.FabricRuntime#registerStatefulServiceFactoryAsync(java.lang.String,system.fabric.StatefulServiceFactory,java.time.Duration) |
|
| StatefulServicePartition | ||
| StatefulServiceReplica |
Defines behavior that governs the lifecycle of a replica, such as startup, initialization, role changes, and shutdown.
Remarks:Stateful service types must implement this interface. The logic of a stateful service type includes behavior that is invoked on Primary replicas and behavior that is invoked on Secondary replicas. If the service author wants to make use of the provided FabricReplicator, then the service must also implement StateProvider to use the implementation of StateReplicator that is provided by FabricReplicator |
|
| StatelessServiceFactory |
Represents a stateless service factory that is responsible for creating instances of a specific type of stateless service.
Remarks:Stateless service factories are registered with the FabricRuntime by service hosts via system.fabric.FabricRuntime#registerStatelessServiceFactory(java.lang.String,system.fabric.StatelessServiceFactory) or system.fabric.FabricRuntime#registerStatelessServiceFactoryAsync(java.lang.String,system.fabric.StatelessServiceFactory,java.time.Duration) |
|
| StatelessServiceInstance |

|
Enums
| CredentialType | ||
| FabricClientRole |
Represents the fabric client security role. |
|
| FabricErrorCode | ||
| FaultType |
Indicates the type of fault that a service reports: invalid, transient or permanent.
Remarks : Services can report faults during runtime by using the reportFault(FaultType faultType) method to indicate the type of fault. |
|
| MoveCost | ||
| OperationType |
Specifies the type of operation that is received via the copy or replication stream. |
|
| PackageSharingPolicyScope |
Represents the scope for the PackageSharingPolicy |
|
| PartitionAccessStatus |
Enumerates the access status of the partition.
Remarks: system.fabric.PartitionAccessStatus is used to check that a read or write operation is allowed. When service replicas handle a client request, they should verify that the system is in a state that allows processing. By checking the getReadStatus() or getwriteStatus() as appropriate, the replica can be notified of conditions that prevent correct operation. Note that write operations might still see an exception from the replicator for one of these conditions, because the condition might change between the getwriteStatus() check and the call to replicateAsync(OperationData operationData, SequenceNumber sequenceNumber, CancellationToken cancellationToken). |
