Record Class Diagnostic

java.lang.Object
java.lang.Record
ca.mcscert.jpipe.compiler.model.Diagnostic
Record Components:
level - severity of the diagnostic.
source - path to the file that triggered it.
line - 1-based source line, or 0 if unknown.
column - 0-based column offset, or 0 if unknown.
message - human-readable description.
public record Diagnostic(Diagnostic.Level level, String source, int line, int column, String message) extends Record
A single diagnostic message produced during compilation.

line and column carry the source location when known; both are 0 when no location is available (ANTLR lines are 1-based, so 0 is a safe sentinel).

  • Field Details

    • UNKNOWN_LOCATION

      public static final int UNKNOWN_LOCATION
      Sentinel value for line and column when no location is known.

      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.
