Working with tables in LuaJava

[slava110]

Hi. How to properly work with tables in LuaJava?

Case 1:

For example, I want to get all keys or values of certain table.
In vanilla Lua you can do it using pairs function to iterate over table.
How to properly iterate over table on Java side though? Do I need to use run for that? Maybe there's more elegant solution?
Also maybe it's possible to get keys of table on C side properly without any iteration at all?

Case 2:

If I want to insert into table or sort table in Lua I can use table.sort and table.insert. But there's no hooks to do that from Java side. Should I use run in this case too?

for (Object entry : lua.toList(index)) {
    workWithEntry();
}

A large part of this library is lightweight wrappers of Lua C API, with which you can do almost anything. So you might probably want try that first.

Anyway:

Case 1

(You will need to push the table onto the Lua stack before doing the following.)

There is mainly two ways:

1. Use toList or toMap.
2. Use next to iterate through tables manually.

Case 2

Yes, you will probably want to use run for this. (You can also use the Lua C API, but it can get a bit tedious.)
