Description

What about enabling the builders (ToStringBuilder, EqualsBuilder, etc.) that use reflection to use annotations to find the field to include?

Something like:

ToStringBuilder.annotationsBasedToString(Object object, Class<Annotation> class, Class<?> reflectUpToClass)

One could use the JPA-Annotation @ID for example, espescially for Equals- and HashCodeBuilder. There should also be some default annotation comming with LangTwo.

Usage:

public class User
{
@StringRepresentation
@EqualsAndHashCode
private String name

@StringRepresentation
private String email;

private String password;

// ...

@Override
public String toString()

{ return annotationsBasedToString(this); }

@Override
public boolean equals(Object other)

{ return annotationsBasedEquals(this, other); }

@Override
public int hashCode()

{ return annotationsBasedHashCode(this); }

}
