public class Properties
extends MMObjectBuilder

The properties builder can contain key/value pairs for any other node in MMBase. When using bridge, properties can be set and get using the 'nodemanager' function 'get' and 'set' on this builder. In core, the (legacy?) methods on MMObjectNode should still work. Example code for bridge:

      <mm:cloud rank="administrator">
        <div>
          <mm:import id="key">test</mm:import>
          <mm:import id="value"><mm:time time="now" /></mm:import>
          <mm:listnodes type="news" max="1">
            <p>TEST: <mm:function nodemanager="properties" name="get" referids="_node@node,key" /></p>
            <p>TEST: <mm:function nodemanager="properties" name="set" referids="_node@node,key,value" /></p>
            <p>TEST: <mm:function nodemanager="properties" name="get" referids="_node@node,key" /></p>
          </mm:listnodes>
        </div>
      </mm:cloud>

      <mm:nodelistfunction nodemanager="properties" name="list" referids="_node@node">
        <mm:field name="key" />:<mm:field name="value" />
      </mm:nodelistfunction>

Method Detail

getGUIIndicator

public String getGUIIndicator(MMObjectNode node)

Description copied from class: MMObjectBuilder

What should a GUI display for this node. Default the value returned is GUI_INDICATOR ('no info'). Override this to display your own choice (see Images.java). You may want to override MMObjectBuilder.getNodeGUIIndicator(MMObjectNode, org.mmbase.util.functions.Parameters) for more flexibility.

Overrides:

getGUIIndicator in class MMObjectBuilder

Parameters:

node - The node to display

Returns:

the display of the node as a String

getValueNode

protected List<Node> getValueNode(Node node,
                                  String key)

Since:

MMBase-1.8.6

getValue

protected Object getValue(List<Node> prop)

Since:

MMBase-1.8.6

getValue

protected Object getValue(Node node,
                          String key)

Since:

MMBase-1.8.6

getPropertyNodes

protected NodeList getPropertyNodes(Node node)

Since:

MMBase-1.9.1

notify

public void notify(NodeEvent event)

Specified by:

notify in interface NodeEventListener

Overrides:

notify in class MMObjectBuilder

here we handle all the backward compatibility stuff. this method covers for both node and relation events.
