org.antlr.v4.runtime.atn.ErrorInfo

public class ErrorInfo
extends DecisionEventInfo

This class represents profiling event information for a syntax error identified during prediction. Syntax errors occur when the prediction algorithm is unable to identify an alternative which would lead to a successful parse.

ErrorInfo

public ErrorInfo(int decision,
         ATNConfigSet configs,
         TokenStream input,
         int startIndex,
         int stopIndex,
         boolean fullCtx)

Constructs a new instance of the ErrorInfo class with the specified detailed syntax error information.

Parameters:

decision - The decision number

configs - The final configuration set reached during prediction prior to reaching the ATNSimulator.ERROR state

input - The input token stream

startIndex - The start index for the current prediction

stopIndex - The index at which the syntax error was identified

fullCtx - true if the syntax error was identified during LL prediction; otherwise, false if the syntax error was identified during SLL prediction
