Imports

org.antlr.v4.runtime.ANTLRErrorListener, .Parser, .RecognitionException, .Token, .TokenStream

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.

Since: 4.3
