public BuilderSupport()

public BuilderSupport(Closure nameMappingClosure, BuilderSupport proxyBuilder)

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)
