IceGrid::Query

Overview

[ "ami" ] interface Query

The IceGrid query interface. This interface is accessible to Ice clients who wish to look up well-known objects.

Operation Index

findObjectById — Find a well-known object by identity.
findObjectByType — Find a well-known object by type.
findObjectByTypeOnLeastLoadedNode — Find a well-known object by type on the least-loaded node.
findAllObjectsByType — Find all the well-known objects with the given type.
findAllReplicas — Find all the object replicas associated with the given proxy.

Operations

Object*

Anchor
findObjectById findObjectById

findObjectById(Ice::Identity id)

Find a well-known object by identity.

Parameters

id — The identity.

Return Value

The proxy or null if no such object has been found.

Object*

Anchor
findObjectByType findObjectByType

findObjectByType(string type)

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

Parameters

type — The object type.

Return Value

The proxy or null, if no such object has been found.

Object*

Anchor
findObjectByTypeOnLeastLoadedNode findObjectByTypeOnLeastLoadedNode

findObjectByTypeOnLeastLoadedNode(string type, IceGrid::LoadSample sample)

Find 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.

Parameters

type — The object type.
sample — The sampling interval.

Return Value

The proxy or null, if no such object has been found.

Ice::ObjectProxySeq

Anchor
findAllObjectsByType findAllObjectsByType

findAllObjectsByType(string type)

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

Parameters

type — The object type.

Return Value

The proxies or an empty sequence, if no such objects have been found.

Ice::ObjectProxySeq

Anchor
findAllReplicas findAllReplicas

findAllReplicas(Object* proxy)

Find all the object replicas associated with the given proxy. If the given proxy is not an indirect proxy from a replica group, an empty sequence is returned.

Parameters

proxy — The object proxy.

Return Value

The proxies of each object replica or an empty sequence, if the given proxy is not from a replica group.
