IXRItemCollection::Contains (Compact 2013)

3/28/2014

This method determines whether an item is in this collection.

Syntax

virtual bool STDMETHODCALLTYPE Contains(
    __in XRValue* pValue
) = 0;

Parameters

• pValue
  [in] Pointer to an XRValue object that represents the item to locate in this collection.

Return Value

Returns true if the item is found in the collection; otherwise, returns false.

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 IXRItemCollection::GetCount.

To use a specific interface pointer type, use the helper template version of this method that XAML for Windows Embedded provides. 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.

.NET Framework Equivalent
