Constructor Detail

GridCacheVersionConflictContext

public GridCacheVersionConflictContext(CacheObjectValueContext ctx,
                                       GridCacheVersionedEntry<K,V> oldEntry,
                                       GridCacheVersionedEntry<K,V> newEntry)

Constructor.

Parameters:

oldEntry - Old entry.

newEntry - New entry.

Method Detail

oldEntry

public GridCacheVersionedEntry<K,V> oldEntry()

Gets old (existing) cache entry.

Returns:

Old (existing) cache entry.

newEntry

public GridCacheVersionedEntry<K,V> newEntry()

Gets new cache entry.

Returns:

New cache entry.

valueContext

public CacheObjectValueContext valueContext()

Gets cache object context.

Returns:

Cache object context.

useOld

public void useOld()

Force cache to ignore new entry and leave old (existing) entry unchanged.

useNew

public void useNew()

Force cache to apply new entry overwriting old (existing) entry.

merge

public void merge(@Nullable
                  V mergeVal,
                  long ttl,
                  long expireTime)

Force cache to use neither old, nor new, but some other value passed as argument. In this case old value will be replaced with merge value and update will be considered as local.

Also in case of merge you have to specify new TTL and expire time explicitly. For unlimited TTL use 0.

Parameters:

mergeVal - Merge value or null to force remove.

ttl - Time to live in milliseconds (must be non-negative).

expireTime - Expire time.
