Redirect annotation

While @LMethod methods may simply acts as a proxy to Glowstone methods, implementing fields is a harder problem. How can we keep fields up to date, especially for primitive values?

Our solution was to replace accesses and assignments of fields with a @LField and @LRedirect annotation against invokes of a getter and setter method.

These are the rules you have to follow:

• Getter and setters must be declared immediately after their field
• Every annotated field must have getters and setters. (Final fields should only have getters)
• There must be a getter and setter for every version that's in the @LField annotation
• The name of getters and setters don't matter. They are detected by their @LGetter or @LSetter annotation respectively.

Here's an example:

@LRedirect
@LField(version = { V1_11_R1, V1_12_R1 })
public int age;
@LGetter(version = { V1_11_R1, V1_12_R1 })
public int ageGetter() {
    return glowEntity.getAge();
}
// This setter applies for version 1.11
@LSetter(version = V1_11_R1)
public void ageSetter(int age) {
    glowEntity.setAge(age);
}
// This one is for version 1.12
@LSetter(version = V1_12_R1)
public void ageSetter2(int age) {
    glowEntity.setAge(Math.abs(age));
}
