public abstract class FactoryBuilderSupport extends Binding
Mix of BuilderSupport and SwingBuilder's factory support. Warning: this implementation is not thread safe and should not be used across threads in a multi-threaded environment. A locking mechanism should be implemented by the subclass if use is expected across multiple threads.

Add an attribute delegate so it can intercept attributes being set. Attribute delegates are fired in a FILO pattern, so that nested delegates get first crack.

It will call attributeDelegates before passing control to the factory

A hook after the factory creates the node and before attributes are set.
It will call any registered postInstantiateDelegates, if you override
this method be sure to call this impl somewhere in your code.

data
- the data retrieved from a compatible getContinuationData callA 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)

parent
- the object from the parent nodechild

Sets the builder to be used as a proxy.

name
- the name of the variable to setvalue
- the new value for the given variable Switches the builder's proxyBuilder during the execution of a closure.
This is useful to temporary change the building context to another builder
without the need for a contrived setup. It will also take care of restoring
the previous proxyBuilder when the execution finishes, even if an exception
was thrown from inside the closure.
builder
- the temporary builder to switch to as proxyBuilder.closure
- the closure to be executed under the temporary builder. Switches the builder's proxyBuilder during the execution of a closure.
This is useful to temporary change the building context to another builder
without the need for a contrived setup. It will also take care of restoring
the previous proxyBuilder when the execution finishes, even if an exception
was thrown from inside the closure. Additionally it will use the closure's
result as the value for the node identified by 'name'.

- the temporary builder to switch to as proxyBuilder.name
