<entry><p>Purpose: </p> </entry>
<entry><p>APPARC can delete (unload) data recognizers in order to save memory.
This constant determines whether the unload feature is enabled. </p> <p>This
value operates in conjunction with <xref href="GUID-2662DE97-0C4C-5536-BA5C-B338C031FCF2.dita">KApaUnloadRecognizersTimeout</xref> which
determines how long a data recognizer must remain unused for before it may
be unloaded. </p> <p>The value of this constant provided by Symbian is zero,
which means that, by default, the feature is not switched on. </p> </entry>
