Base class for various system services, such as grain directory, reminder service, etc. Made public for GrainService to inherit from it. Can be turned to internal after a refactoring that would remove the inheritance relation.

Constructors

SystemTarget()

Only needed to make Reflection happy.

Properties

ActivationServices	Gets the IServiceProvider that provides access to the grain activation's service container.
Deactivated	Gets the Task which completes when the grain has deactivated.
GrainId	Gets the grain identity.
GrainReference	Gets a reference to this grain.
IsLowPriority
Scheduler	Gets the scheduler.
Silo	Silo address of the system target.

Methods

Activate(Dictionary<String,Object>, CancellationToken)	Start activating this instance.
Activate(Dictionary<String,Object>, Nullable<CancellationToken>)	Start activating this instance.
Deactivate(DeactivationReason, CancellationToken)	Start deactivating this instance.
Deactivate(DeactivationReason, Nullable<CancellationToken>)	Start deactivating this instance.
Dispose()
GetComponent<TComponent>()	Gets the component with the specified type.
GetExtension<TExtensionInterface>()	Returns the grain extension registered for the provided `TExtensionInterface`.
GetOrSetExtension<TExtension,TExtensionInterface>(Func<TExtension>)	Binds an extension to an addressable object, if not already done.
GetTarget<TTarget>()	Gets the target.
Migrate(Dictionary<String,Object>, CancellationToken)
Migrate(Dictionary<String,Object>, Nullable<CancellationToken>)
ReceiveMessage(Object)	Submits an incoming message to this instance.
RegisterTimer(Func<Object,Task>, Object, TimeSpan, TimeSpan, String)	Registers a timer to send regular callbacks to this grain. This timer will keep the current grain from being deactivated.
RegisterTimer(Func<Object,Task>, Object, TimeSpan, TimeSpan)	Registers a timer to send regular callbacks to this grain. This timer will keep the current grain from being deactivated.
Rehydrate(IRehydrationContext)
SetComponent<TComponent>(TComponent)	Sets the provided value as the component for type `TComponent`.
ToString()	Override of object.ToString()

Explicit Interface Implementations

IEquatable<IGrainContext>.Equals(IGrainContext)	Indicates whether the current object is equal to another object of the same type.
IFormattable.ToString(String, IFormatProvider)
IGrainContext.ActivationId	Gets the activation id.
IGrainContext.Address	Gets the activation address.
IGrainContext.GrainInstance	Gets the grain instance, or `null` if the grain instance has not been set yet.
IGrainContext.ObservableLifecycle	Gets the observable Grain lifecycle, which can be used to add lifecycle hooks.
ISpanFormattable.TryFormat(Span<Char>, Int32, ReadOnlySpan<Char>, IFormatProvider)
ITargetHolder.GetComponent<TComponent>()	Gets the component with the specified type.

Extension Methods

GetGrainExtension<TComponent>(IGrainContext)	Used by generated code for IGrainExtension interfaces.
AsReference(IAddressable, Type)	Returns a typed reference to the provided grain.
AsReference<TGrainInterface>(IAddressable)	Returns a typed reference to the provided grain.
BindGrainReference(IAddressable, IGrainFactory)	Binds the grain reference to the provided IGrainFactory.
Cast(IAddressable, Type)	Returns a typed reference to the provided grain.
Cast<TGrainInterface>(IAddressable)	Returns a typed reference to the provided grain.
GetGrainId(IAddressable)	Returns the grain id corresponding to the provided grain.
GetPrimaryKey(IAddressable, String)	Returns the Guid representation of a grain primary key.
GetPrimaryKey(IAddressable)	Returns the Guid representation of a grain primary key.
GetPrimaryKeyLong(IAddressable, String)	Returns the `long` representation of a grain primary key.
GetPrimaryKeyLong(IAddressable)	Returns the `long` representation of a grain primary key.
GetPrimaryKeyString(IAddressable)	Returns the `string` primary key of the grain.
IsPrimaryKeyBasedOnLong(IAddressable)	Returns whether part of the primary key is of type `long`.
DeactivateAsync(IGrainContext, DeactivationReason, Nullable<CancellationToken>)	Deactivates the provided grain.
DeactivateAsync(IGrainContext, DeactivationReason, CancellationToken)	Deactivates the provided grain.
ScheduleTask(SystemTarget, Action)	Schedules the provided `action` on the SystemTarget's Orleans.Runtime.ISchedulingContext.
ScheduleTask(SystemTarget, Func<Task>)	Schedules the provided `action` on the SystemTarget's Orleans.Runtime.ISchedulingContext.
ScheduleTask<T>(SystemTarget, Func<Task<T>>)	Schedules the provided `action` on the SystemTarget.
