问题描述
我已经阅读了有关创建可扩展哈希表 Extendable Hashing 的 wiki 页面。现在我正在尝试将其实现到程序中以更好地理解它，但我无法弄清楚如何将目录实际指向存储桶。
目录类：
int GlobalDepth = 1;
int directories[];
public Directory() {
int temp = (int)Math.pow(2,GlobalDepth);
loadDirectories(temp);
}
public void loadDirectories(int n) {
for (int i = 0; i < n; i ++) {
String BinaryKey = Integer.toBinaryString(i);
String tempKey = BinaryKey.substring(0,this.GlobalDepth); // LSB
int depthKey = Integer.parseUnsignedInt(tempKey);
this.directories[i] = depthKey;
}
}
public void increaseGlobalDepth() {
this.GlobalDepth ++;
loadDirectories((int)(Math.pow(2,this.GlobalDepth))); // This method might throw an error because i think im changing the array size illegally and should instead create a temp array and copy/equal that array to this.directories
}
桶类：
private SomeObject[] item; // Class I'm using to hold all the information of something
private int Key,MaxBucketsize,LocalDepth = 1;
//Bucket next;
public Bucket() {
}
public Bucket(int BucketSize) {
this.item = new SomeObject[BucketSize]; // Initalises the number of items held in the bucket
this.MaxBucketsize = BucketSize; // Stores the max number of items that can be held in the bucket
}
public SomeObject[] getobjects() {
return this.item;
}
public boolean addobjects(int key,SomeObject item) {
boolean inserted = false;
for (int i = 0; i < this.MaxBucketsize; i ++) {
if (this.item[i] == null) { // only inserts if there is an empty spot in the bucket
this.item[i] = item;
this.item[i].setKey(key);
inserted = true;
break;
}
}
return inserted;
}
做完这一切之后，我不知道如何像在 wiki 页面中那样将这两个链接在一起。
