Interface AsyncQuery

Namespace

IceGrid

Assembly

IceGrid.dll

Finds well-known Ice objects registered with the IceGrid registry.

[SliceTypeId("::IceGrid::Query")]
public interface AsyncQuery : Object

Inherited Members

Object.dispatchAsync(IncomingRequest)

Object.ice_isA(string, Current)

Object.ice_ping(Current)

Object.ice_ids(Current)

Object.ice_id(Current)

Object.ice_staticId()

Remarks

This Async interface maps each Slice operation to an asynchronous method that returns a Task. Your servant class implements this interface by deriving fromAsyncQueryDisp_ or from the Disp_ class for a derived interface. The Slice compiler generated this skeleton interface from Slice interface ::IceGrid::Query.

Methods

findAllObjectsByTypeAsync(string, Current)

Finds all the well-known objects with the given type.

Task<ObjectPrx?[]> findAllObjectsByTypeAsync(string type, Current current)

Parameters

type string

The object type.

current Current

The Current object for the dispatch.

Returns

Task<ObjectPrx[]>

A list of proxies to the well-known objects with the specified type. Can be empty.

findAllReplicasAsync(ObjectPrx?, Current)

Finds all the replicas of a well-known object.

Task<ObjectPrx?[]> findAllReplicasAsync(ObjectPrx? proxy, Current current)

Parameters

proxy ObjectPrx

A proxy that identifies the well-known object.

current Current

The Current object for the dispatch.

Returns

Task<ObjectPrx[]>

A list of proxies to the replicas of the well-known object specified by proxy. Can be empty.

findObjectByIdAsync(Identity, Current)

Finds a well-known object by identity.

Task<ObjectPrx?> findObjectByIdAsync(Identity id, Current current)

Parameters

id Identity

The identity.

current Current

The Current object for the dispatch.

Returns

Task<ObjectPrx>

A proxy to the well-known object, or null if no such object is registered.

findObjectByTypeAsync(string, Current)

Finds a well-known object by type. If there are several objects registered for the given type, the object is randomly selected.

Task<ObjectPrx?> findObjectByTypeAsync(string type, Current current)

Parameters

type string

The object type.

current Current

The Current object for the dispatch.

Returns

Task<ObjectPrx>

A proxy to a well-known object with the specified type, or null if no such object is registered.

findObjectByTypeOnLeastLoadedNodeAsync(string, LoadSample, Current)

Finds a well-known object by type on the least-loaded node. If the registry does not know which node hosts the object (for example, because the object was registered with a direct proxy), the registry assumes the object is hosted on a node that has a load average of 1.0.

Task<ObjectPrx?> findObjectByTypeOnLeastLoadedNodeAsync(string type, LoadSample sample, Current current)

Parameters

type string

The object type.

sample LoadSample

The sampling interval.

current Current

The Current object for the dispatch.

Returns

Task<ObjectPrx>

A proxy to the well-known object, or null if no such object is registered.
