Method Detail

serialize

public IntegerList serialize()

Serialize state descriptors, edge descriptors, and decision→state map into list of ints: 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 sets set-0-interval-count intervals, 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.
