## org.hibernate.cache
Class OSCacheProvider

    java.lang.Object
      org.hibernate.cache.OSCacheProvider

All Implemented Interfaces:
  CacheProvider

    public class OSCacheProvider

extends Object
implements CacheProvider

Support for OpenSymphony OSCache. This implementation assumes that identifiers have well-behaved `toString()` methods.

Author:
  Mathias Bogaert

Field Summary
`static String` | `OSCACHE_CAPACITY` The `OSCache` cache capacity property suffix.
`static String` | `OSCACHE_CRON` The `OSCache` CRON expression property suffix.
`static String` | `OSCACHE_REFRESH_PERIOD` The `OSCache` refresh period property suffix.

Constructor Summary
`OSCacheProvider()`

Method Summary
`Cache` | `buildCache(String region, Properties properties)` Builds a new `Cache` instance, and gets it's properties from the OSCache `Config` which reads the properties file (`oscache.properties`) from the classpath.
`boolean` | `isMinimalPutsEnabledByDefault()`
`long` | `nextTimestamp()` Generate a timestamp
`void` | `start(Properties properties)` Callback to perform any necessary initialization of the underlying cache implementation during SessionFactory construction.
`void` | `stop()` Callback to perform any necessary cleanup of the underlying cache implementation during SessionFactory.close().
