Class IndentRules

Object

gudusoft.gsqlparser.pp2.layout.rules.IndentRules

All Implemented Interfaces:

LayoutRule

public final class IndentRules
extends Object
implements LayoutRule

Indents every line-starting token. The indent width is GFmtOpt.indentLen (default 2) and the level is:

• the SQL scope level (subquery / CTE nesting, from S20) — so a subquery's lines indent under their enclosing query; plus
• one extra level for clause-body continuation lines (stacked columns, AND/OR conjuncts, CASE branches) — i.e. any broken line whose first token is not a master/clause keyword.

So master and clause keywords (SELECT/FROM/WHERE/ JOIN/...) sit at the scope's base column, and the items they govern sit one level in. Only tokens that begin a line (effective linebreaksBefore > 0) are indented; mid-line tokens are untouched.

Priority LayoutPriorities.INDENT (overrides the spacing rule's leading blank). Needs the S20 sql scope. Iterative; read-only over tokens.

Plan reference: §7.3/S28, §7.4/S28.
