isDeltaWrite

protected boolean isDeltaWrite(Set<Flag> flags)

Indicates whether the operation is a delta write. If it is, the previous value needs to be loaded from the cache store so that it can be merged.

canLoad

protected boolean canLoad(Object key)

loadIfNeeded

protected Boolean loadIfNeeded(InvocationContext ctx,

                        throws Throwable

Loads from the cache loader the entry for the given key. A found value is loaded into the current context. The method returns whether the value was found or not, or even if the cache loader was checked.

Parameters:

ctx - The current invocation's context

key - The key for the entry to look up

isRetrieval - Whether or not this was called in the scope of a get

cmd - The command that was called that now wants to query the cache loader

Returns:

Whether or not the entry was found in the cache loader. A value of null means the cache loader was never queried for the value, so it was neither a hit or a miss.

Throws:

Throwable
