Examples of releasePage()

org.chaidb.db.index.btree.bufmgr.PageBufferManager.releasePage()
Changes a page from fixed to unfixed, and move it to look aside link list. If the page number is not found in the buffer, no action is taken. @param pNumber The page number @param dirty Whether the page has become dirty
