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.

Nested Class Summary

static interface

CAstSourcePositionMap.Position This interface encapsulates the source position of an ast node in its source file.

Method Summary

java.util.Iterator<CAstNode>	getMappedNodes() Returns an iterator of all CAstNodes for which this map contains source mapping information.
CAstSourcePositionMap.Position	getPosition(CAstNode n) Returns the position of a given node in its source file, or null if the position is not known or does not exist.

Method Detail

getPosition

CAstSourcePositionMap.Position getPosition(CAstNode n)

Returns the position of a given node in its source file, or null if the position is not known or does not exist.

getMappedNodes

java.util.Iterator<CAstNode> getMappedNodes()

Returns an iterator of all CAstNodes for which this map contains source mapping information.
