Store streams example code

Found in: epoc32ex\Base\Streams\WriteToMany

This example shows how a network of objects can be written to more than one stream in a direct file store, and how the loading of an object from the store into memory may be deferred.

Run the example either under WINS or on the ARMI platform.

• RStoreWriteStream: supports creation and manipulation of a stream in a store

• RStoreReadStream: supports opening and manipulation of a stream in a store

• CDirectFileStore: a direct file store

• TStreamId: stream identification

• TSwizzle: deferred loading mechanism

Found in: epoc32ex\Base\Streams\WriteToEmbedded

This example shows how an object can be externalized to a store embedded within a permanent file store.

Run the example either under WINS or on the ARMI platform.

• RStoreWriteStream: supports creation and manipulation of a stream in a store

• RStoreReadStream: supports opening and manipulation of a stream in a store

• CPermanentFileStore: a permanent file store

• TStreamId: stream identification

• CEmbeddedStore: an embedded store derived from CPersistentStore

Found in: epoc32ex\Base\Streams\StoreMap

This example demonstrates the streaming of a compound object to multiple streams with deferred loading. It also illustrates the use of a store map (CStoreMap).

Run the example either under WINS or on the ARMI platform.

• RStoreWriteStream: supports creation and manipulation of a stream in a store

• RStoreReadStream: supports opening and manipulation of a stream in a store

• CPermanentFileStore: a permanent file store

• CStoreMap: the store map (a table of streamids and associated swizzles; externalizes swizzles as streamids)

• TSwizzle: a device for handling the dual representation of an object as a streamid or as a pointer
