<concept id="GUID-DF1C3E6D-9133-530B-B318-66F0E6CDB3AD" xml:lang="en"><title>Non-persistent

stores</title><shortdesc> A non-persistent store exists for the life of the object which

represents that store.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>A non-persistent store does not have a root stream and does not support

the notion of open and close. A non-persistent store exists for the life of

the object which represents that store.</p>

<p>A non-persistent store object cannot be discarded without losing all the

data. </p>

<p>The main type of non-persistent store is the buffer store, which holds

all its stream data in a memory buffer.</p>
