ModelNode
The primary class of the public management API is org.jboss.dmr.ModelNode
A ModelNode is wrapper around a value. The value is typically some basic JDK type. A ModelNode exposes a getType() method. This method returns a value of type org.jboss.dmr.ModelType, which is an enum of all the valid types of values.
A ModelNode has keys.
The value associated with a key can be obtained with:
ModelNode.get(String)
and it returns another ModelNode instance.
Difference between add() and set()
add() and set() change the internal state of the node differently.
