Select is implemented by Values and PlainSelect.
You can test this online easily:

1. Values

SQL Text
 └─Statements: statement.insert.Insert
    ├─Table: test
    └─select: statement.select.Values
       └─ParenthesedExpressionList: (1, 2, 3)

2. PlainSelect

SQL Text
 └─Statements: statement.insert.Insert
    ├─Table: test
    └─select: statement.select.PlainSelect
       └─selectItems: statement.select.SelectItem
          └─LongValue: 1
