* Returns a hash code value for the object. This method is * supported for the benefit of hash tables such as those provided by * {@link java.util.HashMap}. */publicnative inthashCode(); 这个方法的注释比较长,就不放出来了。注释指出: hashCode 方法返回散列值。 返回值默认是由对象的地址转...
3).反之,两个对象调用hasCode()返回的哈希码相等,这两个对象不一定相等。 即严格的数学逻辑表示为: 两个对象相等 <=> equals()相等 => hashCode()相等。因此,重写equlas()方法必须重写hashCode()方法,以保证此逻辑严格成立,同时可以推理出:hasCode()不相等 => equals()不相等 <=> 两个对象不相等。 可能...

Additionally, there is complexity not shown in this simple example. Aerospike does not natively support all of Java types. Mapping a java.util.Date to the database requires additional code to convert to an Aerospike representation and back for example. Sub-objects which also need to be stored ...
