public final class ExceptionNode
extends DataNode

Wraps an exception in a DataNode.

ExceptionNode enables the graceful handling of almost any exception thrown during construction of a tree of TypedNodes. The exception can be caught by returning it wrapped in an ExceptionNode, allowing execution to continue while ensuring that the exception is recorded.

Typically the ExceptionNode is eventually displayed in a tree viewer, facilitating debugging.
