Class TagStructureEncoder

java.lang.Object
  org.xerial.mlpress.TagStructureEncoder

public class TagStructureEncoder
extends Object

The TagStructureEncoder repraces tag structures in XML documents to shorter representations by using tagIDs. For example, consider the following XML document:

 
 
   helloworld.txt
   2005/07/24
   
      UTF-8
       ... 
   
 
 
   world.png
   .....
 
 
 

It will be encoded as follows:

 1 2 3 C3 / 4 C4 / 5 6 C6 / 7 C7 / / / 2 8 C8 3 C3 / 9 C9 / 10 C10 / / / $ 
 

where the above integers denote IDs of the start tag names. '/' is end tag, C? (? is an integer) is text container ID, and '$' is the end-of-file. To distinguish IDs of tag names and attribute names is the role of TagDictionary, Thus the TagStructureEncoder simply encodes attribute elements,
