The src
argument was orignally meant to reference the
kernel/field/object that generated the data, in order to support
composite visualizations (that is, viewers that produce a visual based on
the data from several different sources), but launching such viewers in
the current UI is clunky at beset, so this feature isn't used. Viewers
that only visualize a single field's data can probably safely ignore this
arument (and indeed, most of the current ones do).
The field or object that generated the data

New field data that needs to be rendered by this viewer

A list of properties that should be persisted when the app closes, and restored the next time it's launched.
A list of properties that should be persisted when the app closes, and restored the next time it's launched. A common example of a persistent is the zoom/magnification level of the viewer. Be sure to add any relevenant properties to this list in your Viewer subclasses!
Returns the XML representation of this viewer's properties, suitable for saving into a file.
Reset the visualization.
Reset the visualization. An optional operation; subclasses must override this method or else it does nothing.
Parses the XML tag produced by the propertiesTag
method and restores
any saved valued to this Viewer.
Base trait for classes that visualize field data.
One of the design goals for Viewers is to have any of their user configurable options persist across invocations of the debugger. To this end, all Viewers maintain a list of properties that wrap the values they need to save across debugger sessions. Each cogdebugger.Property is capable of generating an XML tag describing the state of that property, and Viewers are capable of collecting those tags and nesting them inside another tag specific to the Viewer instance.
