CoGaDB::BufferObject Struct Reference

Abstract object with holds a Page and more information of it. Holds also Pointer to previous or next pages, which holds also data of the same column. This double linked list will be created by BufferManager. Iterate with prev() and next(). For debugging, printStatus() prints the page-status-byte of this and all next pages. More...

Detailed Description

Abstract object with holds a Page and more information of it. Holds also Pointer to previous or next pages, which holds also data of the same column. This double linked list will be created by BufferManager. Iterate with prev() and next(). For debugging, printStatus() prints the page-status-byte of this and all next pages.
