    - #### BuilderSupport

          public BuilderSupport​(BuilderSupport proxyBuilder)

    - #### BuilderSupport

          public BuilderSupport​(Closure nameMappingClosure,
                                BuilderSupport proxyBuilder)

  - ### Method Detail

    - #### getCurrent

          protected Object getCurrent()

    - #### setCurrent

          protected void setCurrent​(Object current)

    - #### invokeMethod

          public Object invokeMethod​(String methodName)

      Convenience method when no arguments are required.
      Parameters:
        `methodName` - the name of the method to invoke
      Returns:
        the result of the call

    - #### invokeMethod

          public Object invokeMethod​(String methodName,
                                     Object args)

      Description copied from interface: `GroovyObject`
      Invokes the given method.
      Parameters:
        `methodName` - the name of the method to call
        `args` - the arguments to use for the method call
      Returns:
        the result of invoking the method

    - #### doInvokeMethod

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

    - #### 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).
      Parameters:
        `closure` - the closure on which to call setDelegate()
        `node` - the node value that we've just created, which could be a builder

    - #### setParent

          protected abstract void setParent​(Object parent,
                                            Object child)

    - #### createNode

          protected abstract Object createNode​(Object name)

    - #### createNode

          protected abstract Object createNode​(Object name,
                                               Object value)

    - #### createNode

          protected abstract Object createNode​(Object name,
                                               Map attributes)

    - #### createNode

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

    - #### 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.
      Parameters:
        `methodName` - the name of the desired method
      Returns:
        the object representing the name

    - #### 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.
      Parameters:
        `node` - the current node being processed
        `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.
      Parameters:
        `node` - the current node being processed
        `parent` - the parent of the node being processed
      Returns:
        the node, possibly new, that represents the markup element
