Class SCPTreeRecord

java.lang.Object

com.pixelmed.scpecg.SCPTreeRecord

All Implemented Interfaces:

Comparable, TreeNode

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).
