Make a builder

To create a new builder like a the MarkupBuilder or AntBuilder, you have to implement in java (in groovy later too) a subclass of the groovy.util.BuilderSupport class.

The main methods to be implemented are the following :

protected abstract void setParent(Object parent, Object child);
protected abstract Object createNode(Object name); // a node without parameter and closure
protected abstract Object createNode(Object name, Object value); //a node without parameters, but with closure
protected abstract Object createNode(Object name, Map attributes); // a Node without closure but with parameters
protected abstract Object createNode(Object name, Map attributes, Object value); //a node with closure and parameters
protected Object getName(String methodName)

The BuilderSupport.java class

The NodeBuilder example

To be able to write such a code :

we need :

The MarkupBuilder.java class as second example
