Class TreeView

java.lang.Object

org.lsst.ccs.gconsole.plugins.monitor.AbstractMonitorView

org.lsst.ccs.gconsole.plugins.monitor.TreeView

All Implemented Interfaces:

AgentStatusListener, MonitorView

@ConsoleLookup(id="org.lsst.ccs.gconsole.plugins.monitor.MonitorView",
               name="Tree View",
               path="Built-In/Tree",
               description="Monitoring data view that displays its data in a tree of tables.")
public class TreeView
extends AbstractMonitorView

MonitorView that displays monitoring data as a tree of tables. All access to instances of this class, including construction, should happen on the EDT.

Implementation notes

This class maintains "data tree" (instances of DataNode and DataNodeLeaf) that represents hierarchy of data channels displayed by this view. The leaves correspond to specific channels, non-leaf nodes have flags associated with them that affect the display of everything below them.

Separately, there is a SWING JTree displayed by the GUI.Its table consists of DefaultMutableTreeNode instances that wrap either DataNode or TableHolder as their "user objects".

Each DataNode that is not below a flattened DataNode is associated a JTree node. Each JTree node that corresponds to a flattened DataNode has a child that wraps a TableHolder.
