Class JsonReader

java.lang.Object
  org.apache.sling.jcr.contentloader.internal.readers.JsonReader

All Implemented Interfaces:

ContentReader

public class JsonReader
extends java.lang.Object
implements ContentReader

The JsonReader Parses a Json document on content load and creates the corresponding node structure with properties. Will not update protected nodes and properties like rep:Policy and children.

 Nodes, Properties and in fact complete subtrees may be described in JSON files
 using the following skeleton structure (see http://www.json.org for information
 on the syntax of JSON) :

 # the name of the node is taken from the name of the file without the .json ext.
   {

     # optional primary node type, default "nt:unstructured"
     "jcr:primaryType":"sling:ScriptedComponent",
     # optional mixin node types as array
     "jcr:mixinTypes": [ ],


       # "properties" are added as key value pairs, the name of the key being the name
       # of the property. The value is either the string property value, array for
       # multi-values or an object whose value[s] property denotes the property
       # value(s) and whose type property denotes the property type
       "sling:contentClass": "com.day.sling.jcr.test.Test",
       "sampleMulti": [ "v1", "v2" ],
       "sampleStruct": 1,
       "sampleStructMulti": [ 1, 2, 3 ],

       # reference properties start with jcr:reference
       "jcr:reference:sampleReference": "/test/content",

       # path propertie start with jcr:path
       "jcr:path:sampleReference": "/test/path",

       # nested nodes are added as nested maps.
     "sling:scripts":  {

         "jcr:primaryType": "sling:ScriptList",
         "script1" :{
             "primaryNodeType": "sling:Script",
               "sling:name": "/test/content/jsp/start.jsp",
             "sling:type": "jsp",
             "sling:glob": "*"
         }
     }
   }
