Class Nodes.MultiTargetNode

org.prism.Nodes.Node

org.prism.Nodes.MultiTargetNode

Enclosing class:

Nodes

public static final class Nodes.MultiTargetNode
extends Nodes.Node

 Represents a multi-target expression.

     a, (b, c) = 1, 2, 3
        ^^^^^^

 This can be a part of `MultiWriteNode` as above, or the target of a `for` loop

     for a, b in [[1, 2], [3, 4]]
         ^^^^

Field Details

lefts

public final Nodes.Node[] lefts

 Represents the targets expressions before a splat node.

     a, (b, c, *) = 1, 2, 3, 4, 5
         ^^^^

 The splat node can be absent, in that case all target expressions are in the left field.

     a, (b, c) = 1, 2, 3, 4, 5
         ^^^^
 

rest

public final Nodes.Node rest

 Represents a splat node in the target expression.

     a, (b, *c) = 1, 2, 3, 4
            ^^

 The variable can be empty, this results in a `SplatNode` with a `nil` expression field.

     a, (b, *) = 1, 2, 3, 4
            ^

 If the `*` is omitted, this field will contain an `ImplicitRestNode`

     a, (b,) = 1, 2, 3, 4
          ^
 

rights

public final Nodes.Node[] rights

 Represents the targets expressions after a splat node.

     a, (*, b, c) = 1, 2, 3, 4, 5
            ^^^^
