Method weigher

output/java_guava/1.4.13/CacheBuilder.java:492–506

Specifies the weigher to use in determining the weight of entries. Entry weight is taken into consideration by #maximumWeight(long) when determining which entries to evict, and use of this method requires a corresponding call to #maximumWeight(long) prior to calling #build. W
