Class CacheConfigurationBuilder<K,V>

java.lang.Object
  org.ehcache.config.builders.CacheConfigurationBuilder<K,V>

All Implemented Interfaces:

Builder<CacheConfiguration<K,V>>

public class CacheConfigurationBuilder<K,V>
extends java.lang.Object
implements Builder<CacheConfiguration<K,V>>

The CacheConfigurationBuilder enables building CacheConfigurations using a fluent style.

As with all Ehcache builders, all instances are immutable and calling any method on the builder will return a new instance without modifying the one on which the method was called. This enables the sharing of builder instances without any risk of seeing them modified by code elsewhere.
