Class MsgPackDocumentIndexer

  • All Implemented Interfaces:
    MsgPackTokenVisitor
    public final class MsgPackDocumentIndexer
extends Object
implements MsgPackTokenVisitor
    Represents an message pack document indexer. During the indexing of an existing message pack document an MsgPackTree object will be constructed, which corresponds to the structure of the message pack document.

    Example: 

    
 Say we have the following json as message pack document:
 {
   "object1":{ "field1": true, "array":[ 1,2,3]},
   "field2" : "String"
 }
 

     The #index() method will return an MsgPackTree object,
 which has the following structure:
 
          $
        /   \
   field2   object1
     |     /       \
 String  field1   array
          |      /  |  \
         true   1   2   3

    Then this correspond to the following message pack tree structure: 

    NodeTypes:
 

 1object1 : MAP_NODE
 2field1 : LEAF
 2array : ARRAY_NODE
 1field2: LEAF
 
 
    NodeChildsMap:
 

 1object1: field1, array
 2array : 2array1, 2array2, 2array3,
 
 
    LeafMap:
 

 2field1: mapping
 2array1: mapping
 2array2: mapping
 2array3: mapping
 1field2: mapping
