      org.apache.sling.commons.json.jcr.JsonJcrNode

public class JsonJcrNode
extends JSONObject

This class makes it easy to create a JSON object out of a JCR node. It is a shameless copy of JsonItemWriter, but instead of writing the resulting JSON directly to an output, you get a JSONObject that you can deal with.

public JsonJcrNode(javax.jcr.Node node)
            throws JSONException,
                   javax.jcr.RepositoryException

Creates a JSONObject out of node. All node's properties will be reflected in the JSON object. In addition, properties jcr:path and jcr:name are added. Their values are those returned by node.getPath() and node.getName(), respectively.

Parameters:

node - The JCR node to use

Throws:

JSONException - If there's a problem generating the JSON object

javax.jcr.RepositoryException - If there's a problem reading data from the JCR repository

JsonJcrNode

public JsonJcrNode(javax.jcr.Node node,
                   Set<String> propertyNamesToIgnore)
            throws JSONException,
                   javax.jcr.RepositoryException

Creates a JSONObject out of node. All node's properties will be reflected in the JSON object, except those in propertyNamesToIgnore. In addition, properties jcr:path and jcr:name are added. Their values are those returned by node.getPath() and node.getName(), respectively.

Parameters:

node - The JCR node to use

propertyNamesToIgnore - A set of property names that should not be reflected in the resulting JSON object.

Throws:

JSONException - If there's a problem generating the JSON object

javax.jcr.RepositoryException - If there's a problem reading data from the JCR repository
