Method Detail
-
checkInvariant
public void checkInvariant(INode node) throws InvariantChecker.InconsistentNodeModelException
Assert the invariant of completely build node model. Checks that every pointer is correct, e.g.- a parent points to its first child,
- siblings point to the very same parent,
- the offset and length data is in sync, and
- no null fields are present (besides some empty first child pointers).
- Parameters:
node
- an arbitrary node of the complete node model that should be checked.- Throws:
InvariantChecker.InconsistentNodeModelException
- if the node is part of an inconsistent node tree.
