C# 클래스 Antlr4.Runtime.DiagnosticErrorListener

This implementation of IAntlrErrorListener{Symbol} can be used to identify certain potential correctness and performance problems in grammars. "Reports" are made by calling Parser.NotifyErrorListeners(string) with the appropriate message.
  • Ambiguities: These are cases where more than one path through the grammar can match the input.
  • Weak context sensitivity: These are cases where full-context prediction resolved an SLL conflict to a unique alternative which equaled the minimum alternative of the SLL conflict.
  • Strong (forced) context sensitivity: These are cases where the full-context prediction resolved an SLL conflict to a unique alternative, and the minimum alternative of the SLL conflict was found to not be a truly viable alternative. Two-stage parsing cannot be used for inputs where this situation occurs.
