IOpcRelationshipEnumerator::MovePrevious method
Moves the current position of the enumerator to the previous IOpcRelationship interface pointer.
Syntax
HRESULT MovePrevious( [out, retval] BOOL *hasPrevious );
Parameters
- hasPrevious [out, retval]
-
A Boolean value that indicates the status of the IOpcRelationship interface pointer at the current position.
The value of hasPrevious is only valid when the method succeeds.
Value Meaning - TRUE
The current position of the enumerator has been moved to the previous pointer in the collection, and that pointer is valid.
- FALSE
The current position of the enumerator has been moved past the beginning of the enumerator and is no longer valid.
Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code/value | Description |
|---|---|
|
The method succeeded. |
|
The hasPrevious parameter is NULL. |
|
The enumerator is invalid because the underlying set has changed. |
|
The current position already precedes the first item of the enumerator. |
Remarks
When an enumerator is created, the current position precedes the first pointer. To set the current position to the first pointer of the enumerator, call the MoveNext method after creating the enumerator.
