[vJASS] Quick Question about Table

[Pinzu]

Can this method:

        static method getPool takes integer unitTypeId returns thistype
            if (typeTable.has(unitTypeId) then
                return typeTable[unitTypeId]
            endif
            return 0
        endmethod

... be replaced with this?

      static method getPool takes integer unitTypeId returns thistype
            return typeTable[unitTypeId]
        endmethod

As it returns 0 if it doesn't exist right? Thanks in advance.

Unless the table was previously set with a value in that key and it was not cleared/flushed properly before going out of scope and then you try to load that specific key later... yes.

If no entry exists it does return the default-value, yes for an integer, "0". And also, if there exists an entry with value "0" then it would obviously return "0", too.
So the if-clause for checking has() might have influence in an other scenario, but here you probably don't really care from which line the "0" comes from.
