A PluralValue is the equivalent of a map from value -> boolean.
Internally, the data is a Java array.
It is immutable; you cannot add, delete, or modify its contents.
The keys are the data type.
The value is always true.
You can use contains(value) to check whether a value is present.
You can iterate using "foreach value in pluralvalue"
In ASH, you get one of these when you, for example, use "$items[seal tooth, turtle helmet, stolen accordion]"
An ArrayValue is the equivalent of a map from int -> value
Internally, the data is a Java array.
Its size is fixed; you cannot add or delete values.
You can change the stored values.
The key is an index.
The data is whatever you want.
You can use contains(int) to check whether the index is in range
You can iterate using "foreach index, value in array"
In ASH, "effect.get" returns a PluralValue of strings that contains every "action" that can produce that effect.
Code:
> ash $effect[Mallowed Out].all
Returned: aggregate boolean [string]
eat 1 roasted marshmallow => true
cargo effect Mallowed Out => true
This is intentional, since you can iterate over that and get the strings, one after the other, without having to care about an "index".
In the ASH runtime, all of the following are PluralValues:
effect.all
monster.attack_elements
monster.images
monster.random_modifiers
monster.sub_types
I have no opinion how Javascript should represent PluralValues.
