Daniel Sun created GROOVY-8437: ---------------------------------- Summary: Implement an atomic `getAndPut` method for `LRUCache` Key: GROOVY-8437 URL: https://issues.apache.org/jira/browse/GROOVY-8437 Project: Groovy Issue Type: Improvement Reporter: Daniel Sun Assignee: Daniel Sun Fix For: 3.0.0-alpha-2
Currently LRUCache just provides basic cache function(i.e. get, put), which can not make sure same entry will not be added multi-times easily and effectively. In order to resolve the above problem, ConcurrentLinkedHashMap is refined to support `computeIfAbsent`, which is key function for caches. In addition, LRUCache implements `getAndPut`, which is based on the `computeIfAbsent`. Note: the improvement is only available in Groovy 3.0.0+ -- This message was sent by Atlassian JIRA (v6.4.14#64029)
