Member Function Documentation

virtual WvBufStore* WvBufStore::firstsubbuffer (   )  const [inline, protected, virtual, inherited]

Returns the first subbuffer. Returns: the buffer or NULL if none or not supported Reimplemented in WvLinkedBufferStore.

virtual bool WvBufStore::unlinksubbuffer (  WvBufStore *  buffer, bool  allowautofree )  [inline, protected, virtual, inherited]

Unlinks the specified subbuffer. Only autofrees the buffer if allowautofree == true. Returns: the autofree flag for the buffer Reimplemented in WvLinkedBufferStore.
