Constructor Detail

### BuilderSupport

    public BuilderSupport()

### BuilderSupport

    public BuilderSupport(BuilderSupport proxyBuilder)

### BuilderSupport

    public BuilderSupport(Closure nameMappingClosure, BuilderSupport proxyBuilder)

Method Detail

### createNode

    protected Object createNode(Object name)

### createNode

    protected Object createNode(Object name, Object value)

### createNode

    protected Object createNode(Object name, Map attributes)

### createNode

    protected Object createNode(Object name, Map attributes, Object value)

### doInvokeMethod

    protected Object doInvokeMethod(String methodName, Object name, Object args)

### getCurrent

    protected Object getCurrent()

### getName

    protected Object getName(String methodName)

  A hook to allow names to be converted into some other object such as a QName in XML or ObjectName in JMX.
  param:
    methodName the name of the desired method
  return:
    the object representing the name

### invokeMethod

    public Object invokeMethod(String methodName)

  Convenience method when no arguments are required
  param:
    methodName the name of the method to invoke
  return:
    the result of the call

### invokeMethod

    public Object invokeMethod(String methodName, Object args)

### nodeCompleted

    protected void nodeCompleted(Object parent, Object node)

  A hook to allow nodes to be processed once they have had all of their children applied.
  param:
    node the current node being processed
  param:
    parent the parent of the node being processed

### postNodeCompletion

    protected Object postNodeCompletion(Object parent, Object node)

  A hook to allow nodes to be processed once they have had all of their children applied and allows the actual node object that represents the Markup element to be changed
  param:
    node the current node being processed
  param:
    parent the parent of the node being processed
  return:
    the node, possibly new, that represents the markup element

### setClosureDelegate

    protected void setClosureDelegate(Closure closure, Object node)

  A strategy method to allow derived builders to use builder-trees and switch in different kinds of builders. This method should call the setDelegate() method on the closure which by default passes in this but if node is-a builder we could pass that in instead (or do something wacky too)
  param:
    closure the closure on which to call setDelegate()
  param:
    node the node value that we've just created, which could be a builder

### setCurrent

    protected void setCurrent(Object current)

### setParent

    protected void setParent(Object parent, Object child)
