Class MemorySafeLRUMap<K,​V>

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.util.Map<K,​V>, org.apache.commons.collections4.BoundedMap<K,​V>, org.apache.commons.collections4.Get<K,​V>, org.apache.commons.collections4.IterableGet<K,​V>, org.apache.commons.collections4.IterableMap<K,​V>, org.apache.commons.collections4.OrderedMap<K,​V>, org.apache.commons.collections4.Put<K,​V>
    @NotThreadSafe
public class MemorySafeLRUMap<K,​V>
extends org.apache.commons.collections4.map.LRUMap<K,​V>
    The only difference between this class and LRUMap is that it handles memory issues via MemoryLimitCalculator.

    Note: this class is not thread safe! see https://github.com/apache/shenyu/issues/3929
