Constructor Detail

SimplCacheBuilder

public SimplCacheBuilder(CacheDB<T> cacheDB,
                         PersistentDB<T> persistentDB)

This method is used to build the SimplCache object. SimplCache object requires CacheDB and PersistentDB implemented objects.

Parameters:

cacheDB -

persistentDB -

See Also:

CacheDB, PersistentDB

Method Detail

toString

public String toString()

Overrides:

toString in class Object

setCacheMemoryProperties

public SimplCache.SimplCacheBuilder<T> setCacheMemoryProperties(SimplCache.MEMORY_TYPES memory,
                                                                long cacheSize)

This method is used set the cache memory type. Accepts Memory types Enum

Parameters:

memory -

cacheSize - (object count or size in kilobytes)

Returns:

See Also:

There are two memory types: OBJECT_COUNT: Cache Size is maintained in terms of the number of objects in the cache. OBJECT_SIZE: Cache Size is maintained in terms of the size of objects occupied in memory.

setCacheType

public SimplCache.SimplCacheBuilder<T> setCacheType(SimplCache.CACHE_TYPES cacheType)

This methode is used to set the type of cache. There are two types: WRITE_THROUGH: The data is simultaneously updated to cache and memory. WRITE_BACK:The data is updated only in the cache and updated into the memory in later time.

Parameters:

cacheType -

Returns:

See Also:

SimplCache.CACHE_TYPES

setWriteBackInterval

public SimplCache.SimplCacheBuilder<T> setWriteBackInterval(long duration,
                                                            TimeUnit timeUnit)

This method is used to set the interval at which automated write back occurs. By setting write back interval, the data will be written into persistent DB after the given interval regularly.

Parameters:

duration -

timeUnit -

Returns:

setEvictionPolicy

public SimplCache.SimplCacheBuilder<T> setEvictionPolicy(SimplCache.EVICTION_TYPES evictionPolicy)

This method is used to set the eviction policy There are two types of policy: LRU_EVICTION: Least recently used cache object is evicted TIME_EVICTION: The cache object is evicted after given time limit.

Parameters:

evictionPolicy -

Returns:

See Also:

SimplCache.EVICTION_TYPES

setTimeEvictionInterval

public SimplCache.SimplCacheBuilder<T> setTimeEvictionInterval(long duration,
                                                               TimeUnit timeUnit)

This method is used to set time interval after which cache object is evicted from the cache.

Parameters:

duration -

timeUnit -

Returns:

build

public SimplCache<T> build()

This method builds and return SimplCache Object

Returns:
