Detailed Description

RWDBTableEntry is a class for moving RWDBTable metadata in and out of a cache manager class that inherits from RWDBCacheManager.

Synopsis

#include <rw/db/cachemgr.h>
#include <rw/tvhmap.h>

class MyCacheManager : public RWDBCacheManager
{
    void setTable(const RWCString& name, const RWDBTableEntry& tEntry) {
        tCache.insert(name, tEntry);
    }

    RWDBTableEntry getTable(const RWCString& name) const {
        RWDBTableEntry tEntry;
        tCache.findValue(name, tEntry);
        return tEntry;
    }
private:
    RWTValHashMap<RWCString, RWDBTableEntry> tCache;
};

RWvostream& operator<< ( RWvostream &  strm, const RWDBTableEntry &  item  )

friend

Saves the object item to a virtual stream. Recursively calls the function saveGuts(), taking duplicate objects into account. See the discussion on Persistence in the Essential Tools Module User's Guide for more information.

RWFile& operator<< ( RWFile &  file, const RWDBTableEntry &  item  )

friend

Saves the object item to an RWFile. Recursively calls the function saveGuts(), taking duplicate objects into account. See the discussion on Persistence in the Essential Tools Module User's Guide for more information.

RWvistream& operator>> ( RWvistream &  strm, RWDBTableEntry &  obj  )

friend

Restores an RWDBTableEntry into obj from a virtual stream, replacing the previous contents of obj. Recursively calls the function restoreGuts(), taking duplicate objects into account. For more information, see the discussion on Persistence in the Essential Tools Module User's Guide.

RWFile& operator>> ( RWFile &  file, RWDBTableEntry &  obj  )

friend

Restores an RWDBTableEntry into obj from an RWFile, replacing the previous contents of obj. Recursively calls the function restoreGuts(), taking duplicate objects into account. For more information, see the discussion on Persistence in the Essential Tools Module User's Guide.
