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");
