Class NodeHandler

java.lang.Object
  org.mmbase.bridge.jsp.taglib.typehandler.AbstractTypeHandler
      org.mmbase.bridge.jsp.taglib.typehandler.NodeHandler

All Implemented Interfaces:

TypeHandler

public class NodeHandler
extends AbstractTypeHandler

Taglibs handler for Node typed fields. Currently this recognizes node manager names for the guitype (produces dropdowns). If gui-type is not another builder, this falls back to 'AbstractTypeHandler'. This behaviour is legacy. AbstractTypeHandler deals with enumerations genericly.

Since:

MMBase-1.6
