public class SCPTreeRecord extends Object implements Comparable, TreeNode
Instances of the SCPTreeRecord
class represent
nodes in a tree of the SCPTree
class, which in
turn is used by the SCPTreeBrowser
class.
Each record represents a single name-value pair, with the value potentially empty (e.g. a container).
