Modifier and Type	Method	Description
static WritableCachedStore	cacheWritesOnlyWritableCachedStore(WritableCachedStore.Manager mgr)
static WritableCachedStore	createDefaultWritableCachedStore(WritableCachedStore.Manager manager)	creates a WritableCachedStore implementation that uses soft keys and synchronous cleanup for its read cache.
static TweakableCachedStore	createNoCacheCachedStore(CachedStore.Manager mgr)	Always reads directly from manager, as if values are always dirty.
static WritableCachedStore	createNoCacheWritableCachedStore(WritableCachedStore.Manager mgr)	Always reads directly from manager, as if values are always dirty.
static TweakableCachedStore	createNoCleanupCachedStore(CachedStore.Manager manager)
static TweakableCachedStore	createSoftValueCachedStore(CachedStore.Manager manager)	Better to use createSynchronousCleanupSoftKeyCachedStore to prevent the build of cleaned SoftReferences, unless the universe of potential cacheables is small.

Method Detail

createNoCleanupCachedStore

public static TweakableCachedStore createNoCleanupCachedStore(CachedStore.Manager manager)

createSoftValueCachedStore

public static TweakableCachedStore createSoftValueCachedStore(CachedStore.Manager manager)

Better to use createSynchronousCleanupSoftKeyCachedStore to prevent the build of cleaned SoftReferences, unless the universe of potential cacheables is small.

createSynchronousCleanupSoftKeyCachedStore

public static TweakableCachedStore createSynchronousCleanupSoftKeyCachedStore(CachedStore.Manager manager)

createNoCacheCachedStore

public static TweakableCachedStore createNoCacheCachedStore(CachedStore.Manager mgr)

Always reads directly from manager, as if values are always dirty.

createDefaultWritableCachedStore

public static WritableCachedStore createDefaultWritableCachedStore(WritableCachedStore.Manager manager)

creates a WritableCachedStore implementation that uses soft keys and synchronous cleanup for its read cache.

cacheWritesOnlyWritableCachedStore

public static WritableCachedStore cacheWritesOnlyWritableCachedStore(WritableCachedStore.Manager mgr)

createNoCacheWritableCachedStore

public static WritableCachedStore createNoCacheWritableCachedStore(WritableCachedStore.Manager mgr)

Always reads directly from manager, as if values are always dirty. Always writes to back-end storage. Effectively Autoflushing, since every write is flushed.
