UnwrapDataEntry

public UnwrapDataEntry(int cacheId,
                       KeyCacheObject key,
                       CacheObject val,
                       GridCacheOperation op,
                       GridCacheVersion nearXidVer,
                       GridCacheVersion writeVer,
                       long expireTime,
                       int partId,
                       long partCnt,

                       boolean keepBinary,
                       byte flags)

Parameters:

cacheId - Cache ID.

key - Key.

val - Value or null for delete operation.

op - Operation.

nearXidVer - Near transaction version.

writeVer - Write version.

expireTime - Expire time.

partId - Partition ID.

partCnt - Partition counter.

cacheObjValCtx - cache object value context for unwrapping objects.

keepBinary - disable unwrapping for non primitive objects, Binary Objects would be returned instead.

flags - Flags.

Method Detail

unwrappedKey

public Object unwrappedKey()

Unwraps key value from cache key object into primitive boxed type or source class. If client classes were used in key, call of this method requires classes to be available in classpath.

Specified by:

unwrappedKey in interface UnwrappedDataEntry

Returns:

Key which was placed into cache. Or null if failed to convert.

unwrappedValue

public Object unwrappedValue()

Unwraps value value from cache value object into primitive boxed type or source class. If client classes were used in key, call of this method requires classes to be available in classpath.

Specified by:

unwrappedValue in interface UnwrappedDataEntry

Returns:

Value which was placed into cache. Or null for delete operation or for failure.

unwrapKey

public static Object unwrapKey(KeyCacheObject key,
                               boolean keepBinary,
                               CacheObjectValueContext cacheObjValCtx)

unwrapValue

public static Object unwrapValue(CacheObject val,
                                 boolean keepBinary,
                                 CacheObjectValueContext cacheObjValCtx)

toString

public String toString()

Overrides:
