Put.has介绍

[英]A convenience method to determine if this object's familyMap contains a value assigned to the given family & qualifier. Both given arguments must match the KeyValue object to return true.
[中]一种方便的方法，用于确定此对象的familyMap是否包含指定给给定族和限定符的值。两个给定参数必须与KeyValue对象匹配才能返回true。

@Test
 public void testHas() {

  // Bad TS
  Assert.assertFalse(put.has(FAMILY_01, QUALIFIER_01, TS + 1, VALUE_01));
  // Bad Value
  Assert.assertFalse(put.has(FAMILY_01, QUALIFIER_01, TS, QUALIFIER_01));
