Method Summary

Modifier and Type	Method and Description
void	close() Closes the associated FabricCodePackageActivationContext instance and release the associated runtime pointer.
FabricRuntime	create() Creates the system.fabric.FabricRuntime object.
CompletableFuture<FabricRuntime>	createAsync(Duration timeout) Creates the system.fabric.FabricRuntime object asynchronously with the specified timeout parameter.
CompletableFuture<FabricRuntime>	createAsync(Runnable fabricExitCallback, Duration timeout) Creates the system.fabric.FabricRuntime object asynchronously with the specified callback function which will be executed if the underlying runtime terminates or exits for any reason.
FabricCodePackageActivationContext	getActivationContext() Retrieves the current system.fabric.FabricRuntime's CodePackageActivationContext.
CompletableFuture<FabricCodePackageActivationContext>	getActivationContextAsync(Duration timeout) Retrieves the current system.fabric.FabricRuntime’s CodePackageActivationContext asynchronously with the specified parameter.
NodeContext	getNodeContext() Gets the Node Context object that contains information about Fabric Node.
CompletableFuture<NodeContext>	getNodeContextAsync(Duration timeout) Gets Node Context from Fabric Node asynchronously with timeout and cancellation token.
void	registerServiceType(String serviceTypeName, Class<?> serviceTypeImplementation) Associates the specified serviceTypeName with the actual managed Type that implements it. Remarks:Note that this mechanism for service type registration does not require a custom StatelessServiceFactory or StatefulServiceFactory to be provided at registration time. Service Fabric will generate one at runtime and utilize it automatically. If there is a need for a custom implementation of the factory, you can implement StatelessServiceFactory or StatefulServiceFactory and then provide those via the corresponding factory registration methods ( system.fabric.FabricRuntime#registerStatelessServiceFactoryAsync(java.lang.String, system.fabric.StatelessServiceFactory, java.time.Duration) or system.fabric.FabricRuntime#registerStatefulServiceFactoryAsync(java.lang.String, system.fabric.StatefulServiceFactory, java.time.Duration) )
CompletableFuture<?>	registerServiceTypeAsync(String serviceTypeName, Class<?> serviceTypeImplementation, Duration timeout) Asynchronously associates the specified serviceTypeName with the actual managed Type that implements it, with the specified timeout
void	registerStatefulServiceFactory(String serviceTypeName, StatefulServiceFactory factory) Registers the specified StatefulServiceFactory for the specified service type.
CompletableFuture<?>	registerStatefulServiceFactoryAsync(String serviceTypeName, StatefulServiceFactory factory, Duration timeout) Registers the specified StatefulServiceFactory for the specified service type with the specified timeout and cancellationToken.
void	registerStatelessServiceFactory(String serviceTypeName, StatelessServiceFactory factory) Registers the specified StatelessServiceFactory for the specified service type.
CompletableFuture<?>	registerStatelessServiceFactoryAsync(String serviceTypeName, StatelessServiceFactory factory, Duration timeout) Asynchronously registers the specified StatelessServiceFactory for the specified service type, with the specified timeout and cancellationToken

Method Details

close

public void close()

Closes the associated FabricCodePackageActivationContext instance and release the associated runtime pointer.

create

registerServiceType

public void registerServiceType(String serviceTypeName, Class serviceTypeImplementation)

Associates the specified serviceTypeName with the actual managed Type that implements it.

Remarks:Note that this mechanism for service type registration does not require a custom StatelessServiceFactory or StatefulServiceFactory to be provided at registration time. Service Fabric will generate one at runtime and utilize it automatically. If there is a need for a custom implementation of the factory, you can implement StatelessServiceFactory or StatefulServiceFactory and then provide those via the corresponding factory registration methods ( system.fabric.FabricRuntime#registerStatelessServiceFactoryAsync(java.lang.String, system.fabric.StatelessServiceFactory, java.time.Duration) or system.fabric.FabricRuntime#registerStatefulServiceFactoryAsync(java.lang.String, system.fabric.StatefulServiceFactory, java.time.Duration) )
