Interface CAstSourcePositionMap

All Known Implementing Classes:

CAstSourcePositionRecorder

public interface CAstSourcePositionMap

The assumption is that a typical CAst is derived from some kind of textual source file, for which it makes sense to record source position in terms of line and column numbers. This interface encapsulates a mapping from CAstNodes of the an ast to such source positions.
