Hi,
patch [1] introducing ToStringBuilder was merged to master a few days ago
and hopefully additional fixes [2] for ToStringBuilder will be merged soon.
ToStringBuilder is a helper class which eases implementation of toString()
method, which usually contains a lot of class info for logging purposes.
For example take a look at following class:
public class Test {
private boolean flag;
private int number;
private List<String> messages;
private String password;
...
}
Using ToStringBuilder we can easily create toString() method:
@Override
public String toString() {
return ToStringBuilder.forInstance(this)
.append("flag", flag)
.append("number", getNumber())
.append("message", getMessages)
.appendFiltered("password", getPassword())
.build();
}
Using this toString() method we will receive following output (assuming
that attributes as filled in with values):
Test:{flag='false', number='0', message='[msg1, msg2]', password='***'}
For more information about ToStringBuilder please take a look at source code
which is documented by JavaDoc.
It would be great if we start to use this builder in engine code, so I created
patch [3] which refactors existing relevant toString() methods to use
ToStringBuilder.
Thanks
