 bool HasChangedSince([Runtime::InteropServices::Out] System::Object ^ % versionObject);
public bool HasChangedSince (out object versionObject);
abstract member HasChangedSince : obj -> bool
Public Function HasChangedSince (ByRef versionObject As Object) As Boolean

Parameters

versionObject
Object

The response version object assigned at the last call. May be null to get the initial version. At the conclusion of this method call, the object or pointer may be changed so that on a subsequent call we know what version was last observed. The caller should treat this value as an opaque object and should not assume any significance from whether the object pointer changed value or not.

Returns

Boolean

True if the results may have changed since the last call to this method, otherwise false.
