Syntax

public sealed class Query : ApplicationObject

public ref class Query sealed : ApplicationObject

[<Sealed>]
type Query = 
    class
        inherit ApplicationObject
    end

Public NotInheritable Class Query
    Inherits ApplicationObject

Properties

	Name	Description
	Application	Gets the hosting application.(Inherited from ApplicationObject.)
	Description	Gets the description of this query.
	InputStreamBindings	Gets the collection of input stream bindings.
	IsResilient	Gets or sets a value that indicates whether the query is resilient.
	Name	Gets the name of this object.(Inherited from CepObject.)
	OutputStreamBindings	Gets the collection of output stream bindings.
	QueryTemplateName	Gets the name of the query template associated with this query.
	ShortName	Gets the short name of the CEP object. (Inherited from CepObject.)

Methods

	Name	Description
	Delete()	Deletes the object.(Inherited from ApplicationObject.)
	Equals(Object)	(Inherited from Object.)
	GetHashCode()	(Inherited from Object.)
	GetType()	(Inherited from Object.)
	Start()	Starts the query asynchronously.
	Stop()	Stops this query.
	ToString()	(Inherited from Object.)

Extension Methods

	Name	Description
	ToStream<TPayload>()	Overloaded. Creates a new input stream bound to the output event stream of an existing query.(Defined by DynamicQueryCompositionExtensions.)
	ToStream<TPayload>(AdvanceTimeSettings)	Overloaded. Creates a new input stream with given advance time settings bound to the output event stream of an existing query.(Defined by DynamicQueryCompositionExtensions.)
	ToStream<TPayload>(String)	Overloaded. Creates a new input stream with a given name bound to the output event stream of an existing query.(Defined by DynamicQueryCompositionExtensions.)
	ToStream<TPayload>(String, AdvanceTimeSettings)	Overloaded. Creates a new input stream with given name and advance time settings bound to the output event stream of an existing query.(Defined by DynamicQueryCompositionExtensions.)

Remarks

Query objects are based on the specification of event sources and sinks and query templates and their binding to each other. They are entities that are registered in an application on a CEP server, so that they can be started and stopped. For more information, see NIB StreamInsight Server Concepts.
