Class ATNSerializer

java.lang.Object
org.graalvm.shadowed.org.antlr.v4.runtime.atn.ATNSerializer
public class ATNSerializer extends Object
This class represents a target neutral serializer for ATNs. An ATN is converted to a list of integers that can be converted back to and ATN. We compute the list of integers and then generate an array into the target language for a particular lexer or parser. Java is a special case where we must generate strings instead of arrays, but that is handled outside of this class. See ATNDeserializer.encodeIntsWith16BitWords(IntegerList) and

    • serialize

      public IntegerList serialize()
      Serialize state descriptors, edge descriptors, and decision→state map into list of ints. Likely out of date, but keeping as it could be helpful: SERIALIZED_VERSION UUID (2 longs) grammar-type, (ANTLRParser.LEXER, ...) max token type, num states, state-0-type ruleIndex, state-1-type ruleIndex, ... state-i-type ruleIndex optional-arg ... num rules, rule-1-start-state rule-1-args, rule-2-start-state rule-2-args, ... (args are token type,actionIndex in lexer else 0,0) num modes, mode-0-start-state, mode-1-start-state, ... (parser has 0 modes) num unicode-bmp-sets bmp-set-0-interval-count intervals, bmp-set-1-interval-count intervals, ... num unicode-smp-sets smp-set-0-interval-count intervals, smp-set-1-interval-count intervals, ... num total edges, src, trg, edge-type, edge arg1, optional edge arg2 (present always), ... num decisions, decision-0-start-state, decision-1-start-state, ... Convenient to pack into unsigned shorts to make as Java string.
