Constructor Detail

ReferenceCacheEntryImpl

public ReferenceCacheEntryImpl(Object reference,
                               EntityPersister subclassPersister)

Constructs a ReferenceCacheEntryImpl

Parameters:

reference - The reference entity instance

subclassPersister - The specific subclass persister

Method Detail

getReference

public Object getReference()

Provides access to the stored reference.

Returns:

The stored reference

isReferenceEntry

public boolean isReferenceEntry()

Description copied from interface: CacheEntry

Does this entry represent a direct entity reference (rather than disassembled state)?

Specified by:

isReferenceEntry in interface CacheEntry

Returns:

true/false

getSubclass

public String getSubclass()

Description copied from interface: CacheEntry

Hibernate stores all entries pertaining to a given entity hierarchy in a single region. This attribute tells us the specific entity type represented by the cached data.

Specified by:

getSubclass in interface CacheEntry

Returns:

The entry’s exact entity type.

getSubclassPersister

public EntityPersister getSubclassPersister()

getVersion

public Object getVersion()

Description copied from interface: CacheEntry

Retrieves the version (optimistic locking) associated with this cache entry.

Specified by:

getVersion in interface CacheEntry

Returns:

The version of the entity represented by this entry

getDisassembledState

public Serializable[] getDisassembledState()

Description copied from interface: CacheEntry

Get the underlying disassembled state

todo : this was added to support initializing an entity’s EntityEntry snapshot during reattach; this should be refactored to instead expose a method to assemble a EntityEntry based on this state for return.

Specified by:

getDisassembledState in interface CacheEntry

Returns:

The disassembled state
