Java K3 Example

Introduction

The java k3 example is extracted from the most popular open source projects, you can refer to the following example for usage.

Programming language: Java

Class/type: K3

Example#1
File: HashedQuaternaryKeyMap.javaProject: heuermh/dishevelled

 /**
  * Return true if the keys in the specified entry are equal to the specified keys.
  *
  * @param entry entry
  * @param key1 first key
  * @param key2 second key
  * @param key3 third key
  * @param key4 fourth key
  * @return true if the keys in the specified entry are equal to the specified keys
  */
 private boolean isEqualKey(
     final HashEntry<QuaternaryKey<K1, K2, K3, K4>, V> entry,
     final K1 key1,
     final K2 key2,
     final K3 key3,
     final K4 key4) {

 }
