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* 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* 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* findObjectByTypeOnLeastLoadedNode(string type, 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 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 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.
