Proposal for slight extension of PropertySetter
Hello,
Here's a slight extension of org.apache.log4j.config.PropertySetter
(or is it bloat? you decide)! Now you can use other keywords than only
'true' or 'false' to set boolean properties:
We add the following method to PropertySetter:
/**
* Translate a String value to a boolean
*/
private boolean parseBoolean(String value) {
String lvalue = value.toLowerCase(); // non-null and trimming has already been done
if (lvalue.equals("yes") || lvalue.equals("true") ||
lvalue.equals("on") || lvalue.equals("1") ||
lvalue.equals("y") || lvalue.equals("t")) {
return true;
}
if (lvalue.equals("no") || lvalue.equals("false") ||
lvalue.equals("off") || lvalue.equals("0") ||
lvalue.equals("n") || lvalue.equals("f")) {
return false;
}
LogLog.error("Could not interprete '" + value + "' as a boolean...setting to 'false'");
return false;
}
We modify convertArg() with a call to parseBoolean():
/**
Convert <code>val</code> a String parameter to an object of a
given type.
*/
protected
Object convertArg(String val, Class type) {
if(val == null)
return null;
String v = val.trim();
if (String.class.isAssignableFrom(type)) {
return val;
} else if (Integer.TYPE.isAssignableFrom(type)) {
return new Integer(v);
} else if (Long.TYPE.isAssignableFrom(type)) {
return new Long(v);
} else if (Boolean.TYPE.isAssignableFrom(type)) {
return new Boolean(parseBoolean(val));
} else if (Priority.class.isAssignableFrom(type)) {
return OptionConverter.toLevel(v, (Level) Level.DEBUG);
}
return null;
}
Good for the next version or not?
Best regards,
-- David

Ignore my brain deadness, missed the toLowerCase()..
Back to sleep for me.

If you are going to go that far, you may as well do equalsIgnoreCase in the
comparisons to, then things like True and TRUE will still work..
Gives nice compatibility with other config files
Just my 2c
