Class Style.Builder

java.lang.Object
com.nsdev.lettergenerator.model.style.Style.Builder
Enclosing class:
Style
public static final class Style.Builder extends Object
Mutable accumulator for an immutable Style. Omitted properties remain null, so they inherit rather than resetting enclosing defaults. Setters store values without validation; build() takes a snapshot that later setter calls do not change.
