public final class CaffeineSpec extends Object
Caffeine builder configuration.
 
 CaffeineSpec supports parsing configuration off of a string, which makes it especially
 useful for command-line configuration of a Caffeine builder.
 
 The string syntax is a series of comma-separated keys or key-value pairs, each corresponding to a
 Caffeine builder method.
 
initialCapacity=[integer]: sets Caffeine.initialCapacity.
   maximumSize=[long]: sets Caffeine.maximumSize.
   maximumWeight=[long]: sets Caffeine.maximumWeight.
   expireAfterAccess=[duration]: sets Caffeine.expireAfterAccess(java.time.Duration).
   expireAfterWrite=[duration]: sets Caffeine.expireAfterWrite(java.time.Duration).
   refreshAfterWrite=[duration]: sets Caffeine.refreshAfterWrite(java.time.Duration).
   weakKeys: sets Caffeine.weakKeys().
   weakValues: sets Caffeine.weakValues().
   softValues: sets Caffeine.softValues().
   recordStats: sets Caffeine.recordStats().
 Durations are represented by an integer, followed by one of "d", "h", "m", or "s", representing days, hours, minutes, or seconds respectively. There is currently no syntax to request expiration in milliseconds, microseconds, or nanoseconds.
Whitespace before and after commas and equal signs is ignored. Keys may not be repeated; it is also illegal to use the following pairs of keys in a single value:
maximumSize and maximumWeight
   weakValues and softValues
 
 CaffeineSpec does not support configuring Caffeine methods with non-value
 parameters. These must be configured in code.
 
 A new Caffeine builder can be instantiated from a CaffeineSpec using
 Caffeine.from(CaffeineSpec) or Caffeine.from(String).
