Field Details

predicate

public final Nodes.Node predicate

 The node for the condition the `IfNode` is testing.

     if foo
        ^^^
       bar
     end

     bar if foo
            ^^^

     foo ? bar : baz
     ^^^
 

statements

public final Nodes.StatementsNode statements

 Represents the body of statements that will be executed when the predicate is evaluated as truthy. Will be `nil` when no body is provided.

     if foo
       bar
       ^^^
       baz
       ^^^
     end
 

subsequent

public final Nodes.Node subsequent

 Represents an `ElseNode` or an `IfNode` when there is an `else` or an `elsif` in the `if` statement.

     if foo
       bar
     elsif baz
     ^^^^^^^^^
       qux

     end
     ^^^

     if foo then bar else baz end
                     ^^^^^^^^^^^^
