JAU (Java Annotation Based Utilities) announcement

I am glad to announce a first stable beta ;-) of the JAU library (http://code.google.com/p/jau/). Version 0.6 implements the following methods using annotations (and works for POJOs):

• equals
• hashCode
• toString
• compareTo
• copy/clone
• toMap/fromMap (this one creates a java.util.Map with object properties as entries)

Here is a sample use case:

import com.googlecode.jau.*;

@JAUEquals

@JAUHashCode

@JAUToString

@JAUCompare

@JAUCopy

@JAUToMap

public class UserData implements Comparable, Cloneable {

private String firstName;

private String secondName;

private Date birthDate;

private String login;

private String[] rights = new String[] {"view"};

// constructor omitted

public boolean equals(Object obj) {

return JAU.equals(this, obj);

}

public int hashCode() {

return JAU.hashCode(this);

}

public String toString() {

return JAU.toString(this);

}

public int compareTo(Object obj) {

return JAU.compare(this, obj);

}

public UserData clone() throws CloneNotSupportedException {

UserData r = (UserData) super.clone(this);

JAU.copy(this, r);

return r;

}

}

For example, the output for

JAU.toString(new String[][] {{"a", "b"}, {"1", "2"}})

would be

 java.lang.String[][java.lang.String["a", "b"], java.lang.String["1", "2"]]
