现在我要集成 Choco 和布隆过滤器。问题是我想知道 Choco 中的哪个 JAVA 文件是关于搜索过程的,因为我想在每个搜索步骤之后将每个节点的决定存储到布隆过滤器中。
choco源代码:https ://github.com/chocoteam/choco-solver
布隆过滤器源代码:import java.util.BitSet;
公共类 BloomFilter {
private static final int DEFAULT_SIZE = 2 << 24;
private static final int[] seeds = {3,5,7, 11, 13, 31, 37, 61};
private static BitSet bits = new BitSet(DEFAULT_SIZE);
private static SimpleHash[] func = new SimpleHash[seeds.length];
public static void addValue(String value)
{
for(SimpleHash f : func)
bits.set(f.hash(value),true);
}
public static void add(String value)
{
if(value != null) addValue(value);
}
public static boolean contains(String value)
{
if(value == null) return false;
boolean ret = true;
for(SimpleHash f : func)
ret = ret && bits.get(f.hash(value));
return ret;
}
public static void main(String[] args) {
String value = "xkeyideal@gmail.com";
for (int i = 0; i < seeds.length; i++) {
func[i] = new SimpleHash(DEFAULT_SIZE, seeds[i]);
}
add(value);
System.out.println(contains(value));
}
}
类简单哈希 {
private int cap;
private int seed;
public SimpleHash(int cap, int seed) {
this.cap = cap;
this.seed = seed;
}
public int hash(String value)
int result = 0;
int len = value.length();
for (int i = 0; i < len; i++) {
result = seed * result + value.charAt(i);
}
return (cap - 1) & result;
}
}
