embedded objects are not toString-ed like top-level objects
-----------------------------------------------------------
Key: LANG-754
URL: https://issues.apache.org/jira/browse/LANG-754
Project: Commons Lang
Issue Type: Bug
Components: lang.builder.*
Affects Versions: 3.0.1, 2.5
Environment: Linux Ubuntu
java version "1.6.0_24"
Java(TM) SE Runtime Environment (build 1.6.0_24-b07)
Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02, mixed mode)
Reporter: Dominique De Vito
Priority: Minor
I have a simple class 'A' defined as follows:
======================================
public class A {
int p1;
String p2;
B b;
}
======================================
While I execute the following instructions:
ToStringBuilder builder = new ReflectionToStringBuilder(a);
System.out.println(builder.toString());
The output is:
A@3ea981ca[p1=0,p2=<null>,b=B@1ee7b241]
that's normal, without recursion
So, I defined my own style, for recursive toString-ing display:
======================================
class MyStyle extends ToStringStyle {
private final static ToStringStyle instance = new MyStyle();
public MyStyle() {
setArrayContentDetail(true);
setUseShortClassName(true);
setUseClassName(true);
setUseIdentityHashCode(true);
setFieldSeparator(", ");
}
public static ToStringStyle getInstance() {
return instance;
};
@Override
public void appendDetail(final StringBuffer buffer, final String fieldName,
final Object value) {
if (!value.getClass().getName().startsWith("java")) {
buffer.append(ReflectionToStringBuilder.toString(value, instance));
} else {
super.appendDetail(buffer, fieldName, value);
}
}
@Override
public void appendDetail(final StringBuffer buffer, final String fieldName,
final Collection value) {
appendDetail(buffer, fieldName, value.toArray());
}
}
======================================
When I use my custom MyStyle:
String s = ReflectionToStringBuilder.toString(a, MyStyle.getInstance());
System.out.println(s);
The output is:
A@3ea981ca[p1=0, p2=<null>, b=byte@1ee7b241[p4=234]]
So, the name of the class 'B' is not displayed.
I expected something like: b=B@1ee7b241[p4=234]
Instead, the name of the class 'B' is replaced with 'byte'.
I don't know why.
