Service - QueryService

Class: VMware.Hv.QueryService
See also: QueryDefinition, QueryId, QueryResults
Since: Horizon View 6.0

Service Description

The Query Service provides a uniform simple query interface to allow bulk enumeration of entities, using either a paging or "virtual list" model.

To use the paging model, create a query with the QueryService_Create method, get successive results with the QueryService_GetNext method, then release server-side resources with the QueryService_Delete method.
To use the "virtual list" model, use the QueryService_Query method to get one page of results at the offset of your choice. There is no need to free server-side resources using this model, but successive queries may be significantly less performant as a result.
The privileges on an individual query will be based on the queried entity type.

Methods

Methods defined in this Service
QueryService_Create, QueryService_Delete, QueryService_DeleteAll, QueryService_GetCount, QueryService_GetNext, QueryService_Query

QueryService_Create

Create a cursor for iterating though query results efficiently, and return the first set of results. Creates server-side state which should be explicitly deleted via QueryService_Delete. Server side state will also time out eventually.

Parameters

Name	Type	Description
_this	ManagedObjectReference	A reference to the QueryService used to make the method call.
definition	QueryDefinition	query definition.

Return Value

Type	Description
QueryResults	first page of results.

Faults

Type	Description
EntityNotFound	Thrown if any specified entity cannot be found.
InsufficientPermission	Thrown if the user does not have sufficient permission to perform the operation.
InvalidArgument	Thrown if any specified argument is invalid.
InvalidState	Thrown if the per session query limit has been reached.
InvalidType	Thrown if the type of any specified argument is invalid.
UnexpectedFault	Thrown if an unexpected error occurs while performing the operation.
