Class LinkedIdentityHashMap<K,V>

java.lang.Object

com.oracle.graal.compiler.common.LinkedIdentityHashMap<K,V>

All Implemented Interfaces:

Map<K,V>

final class LinkedIdentityHashMap<K,V>
extends Object
implements Map<K,V>

A map that combines IdentityHashMap with LinkedHashMap for the purpose of ensuring a deterministic execution order during a capturing compilation.
