V - the base value type for all caches created by this builderpublic abstract class CacheBuilder<V extends Serializable> extends Object
LoadingCache and Cache instances.
Applications must implement the build(String) and build(String, CacheLoader) methods, to provide a Cache and
LoadingCache implementation. It can either use a standard Guava implementation, or an application specific cache.

|---|---|
abstract com.google.common.cache.Cache<String,V> |
build(String title)
Builds a synchronous cache which does not automatically load values when keys are requested.
|
abstract com.google.common.cache.LoadingCache<String,V> |
build(String title,
com.google.common.cache.CacheLoader<String,V> loader)
Creates a synchronous cache, which either returns an already-loaded value for a given key or atomically computes or retrieves it using the
supplied CacheLoader.
|
CacheBuilder<V> |
expireAfterWrite(long duration,
TimeUnit unit)
Specifies that each entry should be automatically removed from the cache once a fixed duration has elapsed after the entry's creation, or the
most recent replacement of its value.
|
protected long |
getExpireAfterWriteNanos()
Returns the duration in nanoseconds after an entry is created that it should be automatically removed.

Consider build(String, CacheLoader) instead, if it is feasible to implement a CacheLoader.
