Понятно, что OpenRewrite имеет 3 основных метода создания рецептов: декларативный, рефастер и императивный. Речь идет о методе Refaster.
Я создал следующий класс шаблона Refaster для простого изменения кода — обеспечения того, чтобы деление происходило после умножения. (Просто пример для проверки возможностей OpenRewrite)
package com.self.openrewrite_lib.refaster;
import com.google.errorprone.refaster.annotation.AfterTemplate;
import com.google.errorprone.refaster.annotation.BeforeTemplate;
import org.openrewrite.java.template.RecipeDescriptor;
@RecipeDescriptor(name = "Multiply then divide formatter", description = "Ensures that divisions occur after multiplication for accuracy.")
public class MultiplyThenDivide {
@BeforeTemplate
public double divideThenMultiply(double original, double divisor, double multiplier) {
return original / divisor * multiplier;
}
@AfterTemplate
public double multiplyThenDivide(double original, double divisor, double multiplier) {
return original * multiplier / divisor;
}
}
После запуска компиляции mvn в терминале класс Recipe создается в каталоге target/generated-sources/annotations/com/self/openrewrite_lib/refaster .
