org.jbossmx.cluster.watchdog.util.xml
Class XMLObjectCreator  

java.lang.Object
  org.jbossmx.cluster.watchdog.util.xml.XMLObjectCreator

---

public class XMLObjectCreator

extends java.lang.Object

XMLObjectCreator is a utility class for creating Java objects from XML

Examples of XML:

   Example 1:
   <param class="java.lang.String">Hello</param>

   Example 2:
   <param class="java.lang.Boolean">true</param>

   Example 3:
   <param class="com.company.Rational">
     <param class="java.lang.Integer">3</param>
     <param class="java.lang.Integer">4</param>
   </param>

   Example 4:
   <param class="com.company.Thing[]">
     <param class="com.company.Thing">
       <param class="java.lang.Integer">1</param>
       <param class="java.lang.Integer">2</param>
       <param class="java.lang.Integer">3</param>
     </param>
   </param>

 Note that the following fragment

   <param class="java.lang.Thing">
     <param class="java.lang.String">Value</param
   </param>

 can be simplified to:
   <param class="java.lang.Thing">Value</param>

---

printObjectArray

private static void printObjectArray(java.lang.Object[] array)

Prints out the class type and string representation of all the Objects in the array

---

createObject

public static java.lang.Object createObject(org.w3c.dom.Node node)
                                     throws java.lang.Exception

Creates a Java object represented by node

---

getMatchingConstructor

private static java.lang.reflect.Constructor getMatchingConstructor(java.lang.Class classInstance,
                                                                    java.lang.Class[] constructorClasses)

---

isAssignableFrom

private static boolean isAssignableFrom(java.lang.Class[] left,
                                        java.lang.Class[] right)

---

getConstructorClasses

private static java.lang.Class[] getConstructorClasses(java.lang.Object[] objects)

---

getConstructorClasses

private static java.lang.Class[] getConstructorClasses(org.w3c.dom.NodeList nodeList)
                                                throws java.lang.ClassNotFoundException

Gets an array of Classes from the node List, if nodeList is empty of only contains #text node types that a String.class is returned

---

getMatchingNodeCount

private static int getMatchingNodeCount(org.w3c.dom.NodeList nodeList,
                                        java.lang.String nodeName)

Returns the number of nodes in nodeList that have a node name equal to nodeName

---

concatenateNodes

private static java.lang.String concatenateNodes(org.w3c.dom.NodeList nodeList)

Concatenates the values of all the nodes in nodeList

---

getClassFromNode

private static java.lang.Class getClassFromNode(org.w3c.dom.Node node)
