ClassDescriptionStandalone micro-benchmark for ATN hot-path optimizations.This class provides an empty implementation of
graphemesListener, which can be extended to create a listener which only needs to handle a subset of the available methods.This interface defines a complete listener for a parse tree produced bygraphemesParser.Just a hook so we can callInstrumentationmethods like sizeof().Test how fast we can lex Java and some unicode graphemes using old and new unicode stream mechanism.
