Package net.hydromatic.morel.ast

Class Ast.Compute

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.
