update

<K,V> InternalCacheEntry<K,V> update(InternalCacheEntry<K,V> cacheEntry,
                                                 Metadata metadata)

TODO: Adjust javadoc Updates an existing InternalCacheEntry with new metadata. This may result in a new InternalCacheEntry instance being created, as a different InternalCacheEntry implementation may be more appropriate to suit the new metadata values. As such, one should consider the InternalCacheEntry passed in as a parameter as passed by value and not by reference.

Type Parameters:

K - The key type for the entry

V - The value type for the entry

Parameters:

cacheEntry - original internal cache entry

metadata - new metadata

Returns:

a new InternalCacheEntry instance

update

<K,V> InternalCacheEntry<K,V> update(InternalCacheEntry<K,V> cacheEntry,
                                                 V value,
                                                 Metadata metadata)

Similar to update(org.infinispan.container.entries.InternalCacheEntry, org.infinispan.metadata.Metadata) but it also updates the InternalCacheEntry value.

If the same internal cache entry is returned and if it is a mortal cache entry, the returned instance needs to be reincarnated.

Type Parameters:

K - The key type for the entry

V - The value type for the entry

Parameters:

cacheEntry - original internal cache entry

value - new value

metadata - new metadata

Returns:

a new InternalCacheEntry instance or the existing original

createValue

<V> InternalCacheValue<V> createValue(CacheEntry<?,V> cacheEntry)

Creates an InternalCacheValue based on the InternalCacheEntry passed in.

Type Parameters:

V - The value type

Parameters:

cacheEntry - to use to generate a InternalCacheValue

Returns:

an InternalCacheValue

copy

<K,V> CacheEntry<K,V> copy(CacheEntry<K,V> cacheEntry)

Creates a copy of this cache entry and synchronizes serializes the copy process with the update(org.infinispan.container.entries.InternalCacheEntry, org.infinispan.metadata.Metadata). This is requires so that readers of the entry will get an consistent snapshot of the value red.

Type Parameters:

K - The key type for the entry

V - The value type for the entry

createL1

<K,V> InternalCacheEntry<K,V> createL1(K key,
                                                   V value,
                                                   Metadata metadata)

Creates a L1 entry.

Type Parameters:

K - The key type for the entry

V - The value type for the entry

Parameters:

key -

value -

Returns:

a new InternalCacheEntry

getValueFromCtx

<K,V> InternalCacheValue<V> getValueFromCtx(K key,
                                                  InvocationContext ctx)

Retrieve an InternalCacheValue from the provided InvocationContext if an InternalCacheEntry exists, otherwise create InternalCacheEntry from the context's CacheEntry and return its value.

If the entry is not in the context a null value is returned

Type Parameters:

K - The key type for the entry

V - The value type for the entry

Parameters:

key - the key of the entry to be retrieved

ctx - the invocation context from which the value should be retrieved

Returns:

an InternalCacheValue
