<h1 class="topictitle1">IA4HierarchyFolder::GetItemCount</h1>
|
||
|
|
<div><p><strong>Purpose</strong></p>
|
||
|
|
<p>Returns the total count of objects contained in a particular folder in
|
||
|
|
the iSeries™ Navigator
|
||
|
|
hierarchy. This is a required member function.</p>
|
||
|
|
<p><strong>Syntax</strong></p>
|
||
|
|
<pre>HRESULT STDMETHODCALLTYPE GetItemCount(
|
||
|
|
ULONG* pCount
|
||
|
|
);</pre>
|
||
|
|
<p><strong>Parameters</strong></p>
|
||
|
|
<dl><dt class="dlterm">pCount</dt>
|
||
|
|
<dd>Pointer to a long integer that will receive the count of items in the
|
||
|
|
list.</dd>
|
||
|
|
</dl>
|
||
|
|
<p><strong>Return Codes</strong></p>
|
||
|
|
<p>Returns A4HYF_OK_LISTCOMPLETE if the list is completely built and the total
|
||
|
|
count of items is known. Returns A4HYF_OK_LISTNOTCOMPLETE if the list is still
|
||
|
|
being constructed; in this situation the item count represents the count of
|
||
|
|
items in the partially constructed list. Returns A4HYF_E_LISTDATAERROR if
|
||
|
|
an error is encountered while constructing the list. In this situation the
|
||
|
|
item count represents only the items that are already cached on the client.</p>
|
||
|
|
<p><strong>Comments</strong></p>
|
||
|
|
<p>Following a successful return from Activate, Navigator calls this function
|
||
|
|
to obtain the count of objects for the folder that is about to be populated.
|
||
|
|
Following the call to this function, Navigator repeatedly calls ItemAt to
|
||
|
|
obtain the item identifiers for the objects in the folder.</p>
|
||
|
|
<p>For extremely large lists, you may choose to return from Activate before
|
||
|
|
the entire list has been cached on the client. If this is the case, you should
|
||
|
|
return A4HYF_OK_LISTNOTCOMPLETE from GetItemCount. From that point on, GetItemCount
|
||
|
|
will be called by the iSeries Navigator every 10 seconds until A4HYF_OK_LISTCOMPLETE
|
||
|
|
or A4HYF_E_LISTDATAERROR is returned.</p>
