This method searches for the specified item and retrieves the zero-based index of its occurrence within the IXRPathSegmentCollection collection.

Syntax

virtual HRESULT STDMETHODCALLTYPE IndexOf(
    __in IXRPathSegment* pObject,
    __out_opt int* pIndex
) = 0;

Parameters

pObject
[in] Pointer to an IXRPathSegment object that represents an item to locate in this collection.

pIndex
[out] Pointer to an int value that indicates the zero-based index of the last occurrence of pObject within this collection.

Return Value

Returns an HRESULT that indicates success or failure.

Remarks

This method performs a linear search through the collection; therefore, the average execution time is proportional to the number of items. You can retrieve the number of items by using IXRPathSegmentCollection::GetCount.

By default, this method searches the collection starting at the last item, and ending at the first item. Because an object cannot exist more than once in a visual tree, an item can occur only once in this object collection.
