Sub-classes should override this method to create a string which provides information for the parent node only. The string created should be a single line.

childrenInfoString

protected abstract java.lang.String childrenInfoString()

Sub-classes should override this method to return the result of toString on each child, separated by new lines. If the node has no children, this method should return null or the empty string. If the node has 3 children the output should look like:

\n
\n

Note there is no new line character after the last child.

getNodeDataType

public int getNodeDataType(MboRemote mbo)
                    throws MXException,
                           java.rmi.RemoteException

Helper method gets the datatype from attribute nodes when needed.
