Class SimpleKeyGenerator

java.lang.Object

grails.plugin.cache.SimpleKeyGenerator

All Implemented Interfaces:

org.springframework.cache.interceptor.KeyGenerator

public class SimpleKeyGenerator
extends java.lang.Object
implements org.springframework.cache.interceptor.KeyGenerator

Copy of Spring 4.0's SimpleKeyGenerator and SimpleKey Simple key generator. Returns the parameter itself if a single non-null value is given, otherwise returns a SimpleKeyGenerator.SimpleKey of the parameters.

Unlike DefaultKeyGenerator, no collisions will occur with the keys generated by this class. The returned SimpleKeyGenerator.SimpleKey object can be safely used with a ConcurrentMapCache, however, might not be suitable for all Cache implementations.

Since:

4.0
