The
AssociatorsOf method of the
SWbemServices object returns a collection of objects (classes or instances) called endpoints that are associated with a specified object. This method performs the same function that the ASSOCIATORS OF WQL query performs.
This method is called in the semisynchronous mode by default. For more information, see Calling a Method.
The following syntax is language-neutral. For an explanation of this syntax, see
Document Conventions for the Scripting API.
Syntax
objWbemObjectSet = AssociatorsOf(
strObjectPath,
[ strAssocClass = "" ],
[ strResultClass = "" ],
[ strResultRole = "" ],
[ strRole = "" ],
[ bClassesOnly = FALSE ],
[ bSchemaOnly = FALSE ],
[ strRequiredAssocQualifier = "" ],
[ strRequiredQualifier = "" ],
[ iFlags = wbemFlagReturnImmediately ],
[ objwbemNamedValueSet = null ]
)
Parameters
- strObjectPath
-
Required. String that contains the object path of the source class or instance. For more information, see Describing the Location of a WMI Object.
- strAssocClass [optional]
-
String that contains an association class. If specified, this parameter indicates that the returned endpoints must be associated with the source through the specified association class or a class that is derived from this association class.
- strResultClass [optional]
-
String that contains a class name. If specified, this optional parameter indicates that the returned endpoints must belong to or be derived from the class specified in this parameter.
- strResultRole [optional]
-
String that contains a property name. If specified, this parameter indicates that the returned endpoints must play a particular role in their association with the source object. The role is defined by the name of a specified property (which must be a reference property) of an association.
- strRole [optional]
-
String that contains a property name. If specified, this parameter indicates that the returned endpoints must participate in an association with the source object in which the source object plays a particular role. The role is defined by the name of a specified property (which must be a reference property) of an association.
- bClassesOnly [optional]
-
Boolean value that indicates whether a list of class names should be returned rather than actual instances of the classes. These are the classes to which the endpoint instances belong. The default value for this parameter is FALSE.
- bSchemaOnly [optional]
-
Boolean value that indicates whether the query applies to the schema rather than the data. The default value for this parameter is FALSE. It can only be set to TRUE if the strObjectPath parameter specifies the object path of a class. When set to TRUE, the set of returned endpoints represent classes that are suitably associated with the source class in schema.
- strRequiredAssocQualifier [optional]
-
String that contains a qualifier name. If specified, this parameter indicates that the returned endpoints must be associated with the source object through an association class that includes the specified qualifier.
- strRequiredQualifier [optional]
-
String that contains a qualifier name. If specified, this parameter indicates that the returned endpoints must include the specified qualifier.
- iFlags [optional]
-
Integer that specifies additional flags to the operation. The default value for this parameter is wbemFlagReturnImmediately, which calls the method in the semisynchronous mode. This parameter can accept the following values.
| Value | Meaning |
| wbemFlagForwardOnly 32 0x20 | Causes a forward-only enumerator to be returned. Forward-only enumerators are generally much faster and use less memory than conventional enumerators, but they do not allow calls to
SWbemObject.Clone_. |
| wbemFlagBidirectional 0 0x0 | Causes WMI to retain pointers to objects of the enumeration until the client releases the enumerator. |
| wbemFlagReturnImmediately 16 0x10 | Causes the call to return immediately. |
| wbemFlagReturnWhenComplete 0 0x0 | Causes this call to block until the query has completed. This flag calls the method in synchronous mode. |
| wbemFlagUseAmendedQualifiers 131072 0x20000 | Causes WMI to return class amendment data along with the base class definition.
For more information, see Localizing WMI Class Information. |
- objwbemNamedValueSet [optional]
-
Typically, this is undefined. Otherwise, this is an
SWbemNamedValueSet object whose elements represent the context information that can be used by the provider that is servicing the request. A provider that supports or requires such information must document the recognized value names, data type of the value, allowed values, and semantics.
- objWbemObjectSet
-
If the call is successful, an
SWbemObjectSet object is returned.
Return Value
This method does not return a value.
Error Codes
After the completion of the
AssociatorsOf method, the
Err object may contain one of the error codes in the following table.
Note A returned collection with zero elements is not an error.
| Error (Name/Dec/Hex) | Meaning |
| wbemErrAccessDenied 2147749891 0x80041003 | Current user does not have the permission to view one or more of the classes returned by the call. |
| wbemErrFailed 2147749889 0x80041001 | Unspecified error. |
| wbemErrInvalidParameter 2147749896 0x80041008 | Invalid parameter was specified. |
| wbemErrOutOfMemory 2147749894 0x80041006 | Not enough memory to complete the operation. |
| wbemErrNotFound 2147749890 0x80041002 | Requested item was not found. |
