Class InSituValidator

  • public class InSituValidator
    extends java.lang.Object
    This class performs in-situ validation of a tree represented in memory as a NodeInfo object. The standard copy() method is used to copy the tree to a validation pipeline as a sequence of events. The locationId on these events is used to maintain a mapping back to the original nodes in the tree, so that the original tree can be updated with type annotations and expanded defaults reflecting the decisions of the validator.

    Note that if validation fails, the tree will not be in a usable state. For this reason it may be desirable to do the validation twice, once with a Sink as the destination, and only use the in-situ validation once it is known that it will succeed.
