Ast.Compute (morel 0.3.0 API)

java.lang.Object
- net.hydromatic.morel.ast.AstNode
- - net.hydromatic.morel.ast.Ast.FromStep
  - - net.hydromatic.morel.ast.Ast.Group
    - - net.hydromatic.morel.ast.Ast.Compute

Enclosing class:

Ast
```
public static class Ast.Compute
extends Ast.Group
```
A compute clause in a from expression.
Because compute and group are structurally similar, this is a sub-class of Ast.Group, with an empty list of group keys. But remember that the type derivation rules are different.
