Examples of com.google.common.cache.CacheBuilder.maximumSize()

com.google.common.cache.CacheBuilder.maximumSize()

Specifies the maximum number of entries the cache may contain. Note that the cache may evict an entry before this limit is exceeded. As the cache size grows close to the maximum, the cache evicts entries that are less likely to be used again. For example, the cache may evict an entry because it hasn't been used recently or very often.

When {@code size} is zero, elements will be evicted immediately after being loaded into thecache. This has the same effect as invoking {@link #expireAfterWrite expireAfterWrite}{@code (0, unit)} or {@link #expireAfterAccess expireAfterAccess}{@code (0,unit)}. It can be useful in testing, or to disable caching temporarily without a code change. @param size the maximum size of the cache @throws IllegalArgumentException if {@code size} is negative @throws IllegalStateException if a maximum size was already set
