 Bytes maxBytes)

Keep page up to maxBytes for each session.

All pages added to this store must be SerializedPages. You can achieve this by letting a SerializingPageStore delegate to this store.

Parameters:

applicationName - Application.getName()

maxBytes - maximum bytes to keep in session

InMemoryPageStore

protected InMemoryPageStore(String applicationName,
 Supplier<InMemoryPageStore.IMemoryData> dataCreator,
 Map<String,InMemoryPageStore.IMemoryData> datas)

Parameters:

applicationName - Application.getName()

dataCreator - creator of new data

datas - storage for datas
