Should Go runtime ATN export some fields?

[vczyh]

For example, I want access ruleToStartState field, but it is not exported.

Go can't

antlr4/runtime/Go/antlr/v4/atn.go

Line 42 in 2a7904a

ruleToStartState []*RuleStartState

But javascript can.

antlr4/runtime/JavaScript/src/antlr4/atn/ATN.d.ts

Line 11 in 2a7904a

ruleToStartState: RuleStartState[];

Why do you want to access this?

Why do you want to access this?

I am trying to understand the code, the repo implements autocompletion.

https://github.com/mike-lischke/antlr4-c3/blob/44e0b76074b6ca7f0a080cbf12c2e8961b1ff127/src/CodeCompletionCore.ts#L203

[vczyh]

type Transition interface {
	getTarget() ATNState
	setTarget(ATNState)
	getIsEpsilon() bool
	getLabel() *IntervalSet
	getSerializationType() int
	Matches(int, int, int) bool
}

only Matches(int, int, int) accessed.

Some of this is left over from the code I took over and probably could still do with some clean up. But I don't see why Matches has been made public. I would have to look at the code.

Thanks.
I found Java made a lot of methods public. Does Go need to conform to the other languages?

[vczyh]

	public abstract int getSerializationType();

	/**
	 * Determines if the transition is an "epsilon" transition.
	 *
	 * <p>The default implementation returns {@code false}.</p>
	 *
	 * @return {@code true} if traversing this transition in the ATN does not
	 * consume an input symbol; otherwise, {@code false} if traversing this
	 * transition consumes (matches) an input symbol.
	 */
	public boolean isEpsilon() {
		return false;
	}


	public IntervalSet label() { return null; }

	public abstract boolean matches(int symbol, int minVocabSymbol, int maxVocabSymbol);

No - only results. Go is not an OOP language

Yes, but public method should conform.

Says who? ;)

The go runtime is completely different thing to Java and as such while the same functionality and indeed more functionality may well be available, it may operate completely differently. No obligations are placed upon target authors. The java target is the reference point, but it isn't a requirem,ent to copy it.

Well, thank you for your reply, I will try other methods.
