Class MemorySafeLRUMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

org.apache.commons.collections4.map.AbstractHashedMap<K,V>

org.apache.shenyu.common.cache.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
