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. Note that get() actually mutates the node, creating the underlying node if it does not exist.

Adding Multiple Sub-Nodes

ModelNode n = new ModelNode();
n.get("something).set(...)
n.get("something-else).set(...)

Creating an Undefined Node

The following will create an UNDEFINED "something" child node.

ModelNode n = new ModelNode()
n.get("something");
