Method keyEquivalence

output/java_guava/1.4.18/CacheBuilder.java:294–299

Sets a custom Equivalence strategy for comparing keys. By default, the cache uses Equivalence#identity to determine key equality when #weakKeys is specified, and Equivalence#equals() otherwise. @return this CacheBuilder instance (for chaining)
