IXRValueCollection::Contains (Compact 2013)
3/28/2014
This method determines whether an item is in the IXRValueCollection collection.
Syntax
virtual HRESULT STDMETHODCALLTYPE Contains(
__in XRValue * pValue,
__out bool * pResult
) = 0;
Parameters
- pValue
[in] Pointer to an XRValue object that represents the item to locate in this collection.
- pResult
[out] Pointer to a Boolean value that represents whether pValue was found in the collection.
Return Value
Returns S_OK if successful; otherwise, returns an HRESULT error code. For common error codes for XAML for Windows Embedded, see XAML for Windows Embedded Error Messages.
Remarks
This method performs a linear search. Therefore, the average execution time is proportional to the number of items in the collection, which you can retrieve by using IXRValueCollection::GetCount.
To use a specific interface pointer type, use the helper template version of this method provided by XAML for Windows Embedded. When you supply a derived type, this version automatically supplies a type-safe method that implicitly converts the returned type from a generic interface, so you do not have to explicitly call QueryInterface to convert the generic interface into the required object type.
