Contains the results from executing the QueryActivatableWorkflowsCommand against an instance store.
Assembly: System.Activities (in System.Activities.dll)
Thetype exposes the following members.
|ActivatableWorkflowsQueryResult()||Initializes an instance of the class.|
|ActivatableWorkflowsQueryResult(IDictionary<XName, Object>)||Creates an instance of the class and initializes the ActivationParameters property with the data in the dictionary object passed in as a parameter.|
|ActivatableWorkflowsQueryResult(IEnumerable<IDictionary<XName, Object>>)||Creates an instance of the class and initializes the ActivationParameters property with the data in the enumerable dictionary object passed in as a parameter.|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
An instance store should periodically search for activatable workflow instances that belong to a workflow host that uses the store. It should raise the HasActivatableWorkflowEvent when it finds an activatable instance in the persistence store. If the instance store does not find an activatable instance in the persistence store, it should continue to monitor the persistence store for any activatable instances.
After raising the HasActivatableWorkflowEvent, the instance store should stop monitoring the persistence store for activatable instances until it receives and executes the QueryActivatableWorkflowsCommand. The monitoring continues only if the command execution does not return any activatable workflow instances.
When a generic host receives this event, it executes the QueryActivatableWorkflowsCommand against the instance store to obtain activation parameters required to create a workflow host. The generic host uses these activation parameters to create a workflow host, which in turn loads and runs the service instance. The activation parameters for the WAS activation type are: Site Name, Application Path (relative to the site), and Service Path (relative to the application). An instance store could return multiple sets of these three activation parameters.
A generic host is a host that has an XName parameter named ActivationType, which should be set to a value supported by the instance store. Currently, the SQL Workflow Instance Store supports generic hosts with ActivationType parameter set to value: WAS. If the ActivationType is not set at all, the SQL Workflow Instance Store treats the host as a generic host.
The Workflow Management Service that ships with the code named “Dublin” (Application Server Extensions for .NET 4.0) is a generic host that has the activation type set to WAS.
