Class LayoutDegrader

Object

gudusoft.gsqlparser.demos.prettyscore.LayoutDegrader

public final class LayoutDegrader
extends Object

Produces layout-degraded variants of a SQL text that keep every token (so the fidelity gate still passes) but destroy the layout in a known way. Used by the monotonicity tests: a sane scorer must rank formatted > randomIndent > minified and formatted > oneTokenPerLine.

Whitespace only: no token text is ever changed. Lines that lie inside a multi-line token (block comment, string) are left untouched by randomIndent(java.lang.String, gudusoft.gsqlparser.EDbVendor, long, int) so comments stay byte-exact.

Method Summary

Modifier and Type	Method and Description
static String	minify(String sql, EDbVendor vendor) Every token separated by one space on one line (a line comment forces a line break after it).
static String	oneTokenPerLine(String sql, EDbVendor vendor) Every token on its own line, no indentation.
static String	randomIndent(String sql, EDbVendor vendor, long seed, int maxIndent) Keep the line structure, replace every line's indent by a random 0..maxIndent spaces.
