String Arguments
With all the marshalling moved to the 
ArgumentMarshaler
, I started pushing functional-
ity into the derivatives. The first step was to move the 
setBoolean
function into the
BooleanArgumentMarshaller
and make sure it got called correctly. So I created an abstract
set
method.
private
abstract
class ArgumentMarshaler {
protected
boolean booleanValue = false;
private String stringValue;
private int integerValue;
public void setBoolean(boolean value) {
booleanValue = value;
}
public boolean getBoolean() {
return booleanValue;
}
public void setString(String s) {
stringValue = s;
}
public String getString() {
return stringValue == null ? "" : stringValue;
}
public void setInteger(int i) {
integerValue = i;
}
public int getInteger() {
return integerValue;
}
public abstract void set(String s);
}
Then I implemented the 
set
method in 
BooleanArgumentMarshaller
.
private class BooleanArgumentMarshaler extends ArgumentMarshaler {
