C# Class Antlr4.Runtime.Atn.ContextSensitivityInfo

This class represents profiling event information for a context sensitivity.

This class represents profiling event information for a context sensitivity. Context sensitivities are decisions where a particular input resulted in an SLL conflict, but LL prediction produced a single unique alternative.

In some cases, the unique alternative identified by LL prediction is not equal to the minimum represented alternative in the conflicting SLL configuration set. Grammars and inputs which result in this scenario are unable to use PredictionMode.SLL , which in turn means they cannot use the two-stage parsing strategy to improve parsing performance for that input.

startIndex	int	The start index for the current prediction
stopIndex	int	/// The index at which the context sensitivity was /// identified during full-context prediction ///
return	Antlr4.Runtime
