Class ResourcePoolsBuilder

java.lang.Object

org.ehcache.config.builders.ResourcePoolsBuilder

All Implemented Interfaces:

Builder<ResourcePools>

public class ResourcePoolsBuilder
extends java.lang.Object
implements Builder<ResourcePools>

The ResourcePoolsBuilder enables building ResourcePools configurations 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.
