Declaration

C#

public override int GetObjectsCount(

    CriteriaOperator criteria
)

VB.NET

Public Overrides Function GetObjectsCount(
    objectType As Type,
    criteria As CriteriaOperator
) As Integer

Parameters

Name	Type	Description
objectType	Type	A Type object that identifies the type of objects against which the calculation will be performed.
criteria	CriteriaOperator	The CriteriaOperator that specifies the criteria for object selection.

Returns

Type	Description
Int32	An integer value that is the count of non-persistent objects that satisfy the specified criteria.

Remarks

You can handle the NonPersistentObjectSpace.ObjectsCountGetting event to supply custom logic for calculating the GetObjectsCount result. If the ObjectsCountGetting event is not handled, or if the ObjectsCountGettingEventArgs.Count is null, the GetObjectsCount method calls the IObjectSpace.CreateCollection method to calculate the count.
