MDict Library in pure java ！

It supports:
I.lzo(via lzo-core-1.0.5.jar)
II.Ripemd128 key-info decryption.
III.Builders to make Mdx add Mdd .

and is able to do:
I.Basic query.
II.Conjuction search.
III.Fast wildcard match entry.
IV.Fast Fulltext retrieval (also with wild cards).

App Released!

Usage:

1.Basic query:

String key = "happy";
mdict md = new mdict(path);
int search_result = md.lookUp(key, true);//true means to match strictly  
if(search_result!=-1){
  String html_contents = md.getRecordAt(search_result);
  String entry_name = md.getEntryAt(search_result);
}

2.Search in a bunch of dicts:

String key = "happy";
ArrayList<mdict> mdxs = new ArrayList<mdict>();
mdxs.add(path1);
mdxs.add(path2);
RBTree_additive combining_search_tree = new RBTree_additive();
for(int i=0;i<mdxs.size();i++)
{
  mdxs.get(i).size_confined_lookUp(key,combining_search_tree,i,30);
}  	
combining_search_tree.inOrder();//print results stored in the RBTree

/*printed results looks like 【happy____@398825@0@16905@1@16906@1】...【other results】...
how to handle:
String 
html_contents0 = mdxs.get(0).getRecordAt(398825),
html_contents1 = mdxs.get(1).getRecordAt(16905),
html_contents2 = mdxs.get(1).getRecordAt(16906);
...  
...
*/

3. Other search methods

See test/MdTest.java and the newly uploaded mdict-javafx demo! It's not yet complete though.

details

This project was initially converted from xiaoqiangWang's python analyzer.
Use red-black tree and binary-list-searching(mainly) to implement dictionary funcitons.
Feng Dihai(@fengdh)'s mdict-js is of help too, I've just switched to use the same short but elegant binary-list-searching method——reduce().Somehow, this function always returns the first occurence of the entry >= keyword, in a pre-sorted list that contain entries. maybe some mathematician could tell me why, but I've tested over 100000 times without any expectation.
Maybe I should oneday replace red-black tree and the recursive reduce method with Arrays.binarySearch, but I am lazy...

/*via mdict-js
 *note at first time we feed in 0 as start and array.length as end. it must not be array.length-1. 
*/
public static int reduce(int phrase, int[] array,int start,int end) {
	int len = end-start;
	if (len > 1) {
	  len = len >> 1;
	  return phrase > array[start + len - 1]
				? reduce(phrase,array,start+len,end)
				: reduce(phrase,array,start,start+len);
	} else {
	  return start;
	}
}
