Methods

addRef() → int

Increments the reference count of this COM object.

inherited

cancelAsyncCall(IWbemObjectSink? pSink) → void

Cancels any currently pending asynchronous calls based on the IWbemObjectSink pointer, which was originally passed to the asynchronous method.

createClassEnum(BSTR strSuperclass, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx) → IEnumWbemClassObject?

Returns an enumerator for all classes that satisfy selection criteria.

createClassEnumAsync(BSTR strSuperclass, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, IWbemObjectSink? pResponseHandler) → void

Returns an enumeration of all classes that the class provider supports.

createInstanceEnum(BSTR strFilter, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx) → IEnumWbemClassObject?

Creates an enumerator that returns the instances of a specified class according to user-specified selection criteria.

createInstanceEnumAsync(BSTR strFilter, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, IWbemObjectSink? pResponseHandler) → void

Creates an enumerator that asynchronously returns the instances of a specified class according to user-specified selection criteria.

deleteClass(BSTR strClass, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, Pointer<VTablePointer>? ppCallResult) → void

Deletes the specified class from the current namespace.

deleteClassAsync(BSTR strClass, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, IWbemObjectSink? pResponseHandler) → void

Deletes the specified class from the current namespace.

deleteInstance(BSTR strObjectPath, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, Pointer<VTablePointer>? ppCallResult) → void

Deletes an instance of an existing class in the current namespace.

deleteInstanceAsync(BSTR strObjectPath, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, IWbemObjectSink? pResponseHandler) → void

Asynchronously deletes an instance of an existing class in the current namespace.

execMethod(BSTR strObjectPath, BSTR strMethodName, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, IWbemClassObject? pInParams, Pointer<VTablePointer>? ppOutParams, Pointer<VTablePointer>? ppCallResult) → void

Executes a method exported by a CIM object.

execMethodAsync(BSTR strObjectPath, BSTR strMethodName, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, IWbemClassObject? pInParams, IWbemObjectSink? pResponseHandler) → void

Asynchronously executes a method exported by a CIM object.

execNotificationQuery(BSTR strQueryLanguage, BSTR strQuery, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx) → IEnumWbemClassObject?

Executes a query to receive events.

execNotificationQueryAsync(BSTR strQueryLanguage, BSTR strQuery, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, IWbemObjectSink? pResponseHandler) → void

Performs the same task as IWbemServices.execNotificationQuery except that events are supplied to the specified response handler until CancelAsyncCall is called to stop the event notification.

execQuery(BSTR strQueryLanguage, BSTR strQuery, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx) → IEnumWbemClassObject?

Executes a query to retrieve objects.

execQueryAsync(BSTR strQueryLanguage, BSTR strQuery, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, IWbemObjectSink? pResponseHandler) → void

Executes a query to retrieve objects asynchronously.

getObject(BSTR strObjectPath, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, Pointer<VTablePointer>? ppObject, Pointer<VTablePointer>? ppCallResult) → void

Retrieves a class or instance.

getObjectAsync(BSTR strObjectPath, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, IWbemObjectSink? pResponseHandler) → void

Retrieves an object, either a class definition or instance, based on its path.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

openNamespace(BSTR strNamespace, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, Pointer<VTablePointer>? ppWorkingNamespace, Pointer<VTablePointer>? ppResult) → void

Provides the caller with a new IWbemServices pointer that has the specified child namespace as its operating context.

putClass(IWbemClassObject? pObject, WBEM_GENERIC_FLAG_TYPE lFlags, IWbemContext? pCtx, Pointer<VTablePointer>? ppCallResult) → void
