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

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
