Method Details

passivation

public boolean passivation()

If true, data is only written to the cache store when it is evicted from memory, a phenomenon known as 'passivation'. Next time the data is requested, it will be 'activated' which means that data will be brought back to memory and removed from the persistent store. This gives you the ability to 'overflow' to disk, similar to swapping in an operating system.

If false, the cache store contains a copy of the contents in memory, so writes to cache result in cache store writes. This essentially gives you a 'write-through' configuration.

since 14.0. This will always return false

Loops through all individual cache loader configs and checks if fetchPersistentState is set on any of them

preload

public Boolean preload()

Loops through all individual cache loader configs and checks if preload is set on any of them

usingStores

public boolean usingStores()

usingAsyncStore

public boolean usingAsyncStore()

usingSegmentedStore

public boolean usingSegmentedStore()

Returns if any store is StoreConfiguration.segmented()

Returns:

true if any configured store is segmented, otherwise false
