Class DoubleMap

java.lang.Object

org.alfresco.repo.content.transform.DoubleMap

public class DoubleMap
extends java.lang.Object

Provides simple get and put access to a Map like object with a double key that allows either or both keys to be a wild card that matches any value. May not contain null keys or values.

Originally created for mapping source and target mimetypes to transformer configuration data.

For example:

       DoubleMap foodLikes = new DoubleMap("*", "*");
       
       foodLikes.put("cat",   "mouse", "likes");
       
       foodLikes.get("cat", "mouse"); // returns "likes"
       foodLikes.get("cat", "meat");  // returns null
       
       foodLikes.put("dog",   "meat",  "likes");
       foodLikes.put("dog",   "stick", "unsure");
       foodLikes.put("child", "olive", "dislikes");
       foodLikes.put("bird",  "*",     "worms only");
       foodLikes.put("*",     "meat",  "unknown");
       foodLikes.put("*",     "*",     "no idea at all");
       
       foodLikes.get("cat", "mouse"); // returns "likes"
       foodLikes.get("cat", "meat");  // returns "unknown"
       foodLikes.get("cat", "tea");   // returns "unknown"
       foodLikes.get("*",   "mouse"); // returns "no idea at all"
       foodLikes.get("dog", "*");     // returns "no idea at all"
       foodLikes.get("bird","*");     // returns "worms only"
       foodLikes.get("bird","tea");   // returns "worms only"
