The effect is to create an entry in the store map table containing the stream ID and the associated Swizzle; the Swizzle is said to be bound to the stream ID. Creating this entry in the store map is done using <codeph>CStoreMap::BindL()</codeph>.</p> <p>For a container type class <codeph>CCompound</codeph>, the diagram below shows the result of:</p> <ul><li id="GUID-B49D7824-7128-506F-B026-A6F4785C5C94"><p>streaming out the in-memory objects represented by the Swizzles <codeph>iA</codeph>, <codeph>iB</codeph> and <codeph>iC</codeph>.</p> </li> <li id="GUID-F3352249-7B90-5F90-B706-A01DC2C87C41"><p>binding the swizzles with the resulting stream IDs</p> </li> </ul> <p>The other characteristics of a store map follow from this. </p> <fig id="GUID-16CAA671-B195-558E-868A-46463EDEB476"><title/><image href="GUID-4028CDCF-D2E8-5668-A751-A7CFA86CED46_d0e575478_href.png" placement="inline"/></fig> <p>Entries in the store map can be deleted. An entry can be identified either by Swizzle or by stream ID. <codeph>CStoreMap::Unbind()</codeph> deletes an entry identified by Swizzle; <codeph>CStoreMap::Forget()</codeph> deletes an entry identified by stream ID.</p> </conbody></concept>
