Method Detail

getCacheName

java.lang.String getCacheName()

Returns:

the name of the cache

getMemoryStoreSize

long getMemoryStoreSize()

Returns:

the number of elements in the memory cache

getInMemorySize

long getInMemorySize()

Returns:

the size of the memory store for this cache

getSize

long getSize()

Returns:

the entire size of the cache including the number of elements in the memory store plus the number of elements in the disk store

getDiskStoreSize

long getDiskStoreSize()

Returns:

the number of elements in the disk store

getAverageGetTime

float getAverageGetTime()

Returns:

the average time to retrieve a cache element in milliseconds

getCacheHits

long getCacheHits()

Returns:

the number of times a requested item was found in the cache.

getCacheMisses

long getCacheMisses()

Returns:

the number of times a requested element was not found in the cache

getEvictionCount

long getEvictionCount()

Returns:

the number of cache evictions, since the cache was created, or statistics were cleared

getInMemoryHits

long getInMemoryHits()

Returns:

the number of times a requested item was found in memory

getObjectCount

long getObjectCount()

Returns:

gets the number of elements stored in the cache. Caclulating this can be expensive. Accordingly, this method will return three different values, depending on the statistics accuracy setting

getOnDiskHits

long getOnDiskHits()

Returns:

the number of times a requested element was not found in the cache

getMaxElementsInMemory

long getMaxElementsInMemory()

Returns:

get configured maximum elements in memory

getMaxElementsOnDisk

long getMaxElementsOnDisk()

Returns:

get configured maximum elements on disk

getTimeToIdle

long getTimeToIdle()

Returns:

get configured time to idle in seconds before expiring

getTimeToLive

long getTimeToLive()

Returns:

get configured time to live in seconds before expiring
