annotate graal/com.oracle.truffle.api/src/com/oracle/truffle/api/instrument/Visualizer.java @ 15630:2d63ce48d222
Truffle/Source Attribution: Replace direct creation of SourceSection objects with factory methods on Source; two of these greatly simplify source attribution by automatically computing either the row/column start location from a character offset or vice versa, depending on what?s made available from the parser. Minor API change on Visualizer.
