Hi Shorn,
Here's a reflective toString() that handles inherited fields:
/**
* For the specified object, prints names and values of all public
fields,
* both declared and inherited.
*
* @param obj the object
*
* @return a nicely-formatted string containing the names and values of
all public fields,
* both declared and inherited.
*/
public static String toString( Object obj )
{
Class clazz = obj.getClass();
StringBuffer buf = new StringBuffer( 1024 );
buf.append( "[Field Name]\t[Value]\n" );
while ( clazz != null )
{
Field[] field = clazz.getDeclaredFields();
for ( int i = 0; i < field.length; i++ )
{
buf.append( field[i].getName() + ":\t" );
Object field_object = null;
try
{
field_object = field[i].get( obj );
}
catch ( IllegalAccessException iae )
{
buf.append( "<" );
buf.append( iae.getMessage() );
buf.append( ">" );
}
if ( field_object != null )
{
buf.append( "\"" );
buf.append( field_object );
buf.append( "\"" );
}
else
{
buf.append( "<null>" );
}
buf.append( "\n" );
}
clazz = clazz.getSuperclass(); //Recurse super classes
}
return ( buf.toString() );
}
Feel free to incorporate this into commons-lang.
Regards,
Ian
