public class ObjectGraphBuilder
extends FactoryBuilderSupport
A builder for creating object graphs.
Each node defines the class to be created and the property on its parent (if
any) at the same time.

|
protected void |
preInstantiate(Object name, Map attributes, Object value)A hook before the factory creates the node. It will call any registered preInstantiateDelegates, if you override this method be sure to call this impl somewhere in your code.
|
|
protected Factory |
resolveFactory(Object name, Map attributes, Object value)This is a hook for subclasses to plug in a custom strategy for mapping names to factories.
