__InstanceProviderRegistration class
The __InstanceProviderRegistration system class registers instance providers in WMI.
The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.
Syntax
class __InstanceProviderRegistration : __ObjectProviderRegistration
{
sint32 InteractionType = 0;
__Provider REF provider;
string QuerySupportLevels[];
boolean SupportsBatching;
boolean SupportsDelete = False;
boolean SupportsEnumeration = True;
boolean SupportsGet = False;
boolean SupportsPut = False;
boolean SupportsTransactions;
};
Members
The __InstanceProviderRegistration class has these types of members:
Properties
The __InstanceProviderRegistration class has these properties.
-
InteractionType
-
-
Data type: sint32
-
Access type: Read/write
Indicates that a class or instance provider supplies data, or retrieves data from WMI and the Common Information Model (CIM) repository. Pull providers support dynamic access to their data; and push providers store their data in the CIM repository, and use WMI to provide access to it. For more information, see Determining Push or Pull Status. The default value is 0 (zero).
-
-
Pull (0)
-
Provider is a pull provider.
-
Push (1)
-
Provider is a push provider.
-
PushVerify (2)
-
Provider is a push-verify provider. Note that push-verify providers are not currently supported.
provider
-
Data type: __Provider
-
Access type: Read-only
Reference to an instance of __Provider that represents the object path to the instance provider. This property is inherited from __ProviderRegistration.
QuerySupportLevels
-
Data type: string array
-
Access type: Read/write
Array of the types of provider-included support for query processing. Class providers do not support all types of queries. Instance providers can set QuerySupportLevels to NULL if they do not support query processing. Providers that support queries implement the IWbemServices::ExecQueryAsync method, and set this property to one or more of the following values.
("WQL:UnarySelect")
("WQL:References")
("WQL:Associators")
("WQL:V1ProviderDefined")
SupportsBatching
-
Data type: boolean
-
Access type: Read/write
Not used.
SupportsDelete
-
Data type: boolean
-
Access type: Read/write
If True, the provider supports data deletion.
True
The provider supports class or instance deletion by implementing either IWbemServices::DeleteClassAsync (class providers), or IWbemServices::DeleteInstanceAsync (instance providers).
False
The provider does not support data deletion, and returns WBEM_E_PROVIDER_NOT_CAPABLE from DeleteClassAsync or DeleteInstanceAsync.
SupportsEnumeration
-
Data type: boolean
-
Access type: Read/write
If True, the provider supports data enumeration.
(True)
The provider supports data enumeration by implementing one of either IWbemServices::CreateClassEnumAsync (class providers), or IWbemServices::CreateInstanceEnumAsync (instance providers).
(False)
The provider does not support data enumeration, and returns WBEM_E_PROVIDER_NOT_CAPABLE from CreateClassEnumAsync or CreateInstanceEnumAsync.
SupportsGet
-
Data type: boolean
-
Access type: Read/write
If True, the class or instance provider supports data retrieval.
True
The provider supports data retrieval by implementing IWbemServices::GetObjectAsync.
False
The provider does not support data retrieval, and returns WBEM_E_PROVIDER_NOT_CAPABLE from GetObjectAsync.
SupportsPut
-
Data type: boolean
-
Access type: Read/write
If True, the class or instance provider supports data modification.
(True)
The provider supports class or instance modification by implementing one of the following methods: IWbemServices::PutClassAsync (class providers), or IWbemServices::PutInstanceAsync (class providers).
(False)
The provider does not support data modification and returns WBEM_E_PROVIDER_NOT_CAPABLE from PutClassAsync or PutInstanceAsync.
SupportsTransactions
-
Data type: boolean
-
Access type: Read/write
Not used.
Remarks
The __InstanceProviderRegistration class is derived from __ObjectProviderRegistration, which is derived from __ProviderRegistration. Only administrators can register an instance provider by creating an instance of __Win32Provider and __InstanceProviderRegistration. Only administrators can delete a provider.
