Call _container().getName()
The name of the instance of the actor is StringConst. It an instance of
the Java class ptolemy.actor.lib.StringConst.
If you pasted another StringConst in, its name would be StringConst1 (I
think) and it would be an instance of the Java class
ptolemy.actor.lib.StringConst.
getName() returns the name of the actor instance which is unique.
In your screen shot, you have a Parameter that is an instance of the
ptolemy.data.expr.TemporaryVariable that is contained in a StringConst
actor.
BTW - You should take a look at the Software Architecture chapter at
http://ptolemy.eecs.berkeley.edu/books/Systems/chapters/SoftwareArchitecture.pdf
of the book
Claudius Ptolemaeus, Editor, /System Design, Modeling, and Simulation
Using Ptolemy II/, Ptolemy.org, 2014.

Hi Christopher,
Thank you for your answers to my questions!
What about the name of the container (i.e., _container)?
When I debugged, I have found that the value of " _container" (red box
in the attached pic) is "StringConst".
If this value is also unique, I want to extract this value instead of
the full qualified classname.
lastIndexOf() may need extra work to extract the value "StringConst".
Do you know any other function to extract the value "StringConst"?
maybe... getUnderBarContainer.
but I can not find that function in source code.
Please, let me know
Thank you

Hi Donghoon,
In Java, the fully qualified classname must be unique. There is
some magic that can be done with different class loaders and such,
but in general, and in Kepler and Ptolemy, the fully qualified
classname will be unique. The fully qualified classname includes
the package, So, ptolemy.actor.lib.StringConstant is one actor.
There can be another actor,
ptolemy.actor.lib.mypackage.StringConstant. Both actors could be
used in a model.
Note that Kepler has actor oriented classes (see
http://ptolemy.eecs.berkeley.edu/publications/papers/07/classesandInheritance/index.htm).
The quick summary of actor oriented classes is that they are
chunks of functionality implemented as Ptolemy models that can be
reused by instantiation or subclassing. The Sinewave actor is an
actor-oriented class. When you are calling
parameter.getContainer().getClassName(), you are getting the
className which may or may not be the same as the Java class name.
Probably the method that is being called is in
ptolemy/kernel/util/NamedObj.java:
/** Return the MoML class name. This is either the
* class of which this object is an instance, or if this
* object is itself a class, then the class that it extends.
* By default, it will be the Java class name of this object.
* This method never returns null.
* @return The MoML class name.
* @see MoMLExportable
* @see #setClassName(String)
*/
@Override
public String getClassName() {
if (_className == null) {
_className = getClass().getName();
}
return _className;
}
_className is set when instantiating clones for actor-oriented
classes.
To get the last part of the fully qualified classname, see the
lastIndexOf() method in the java.lang.String class:
https://docs.oracle.com/javase/8/docs/api/java/lang/String.html#lastIndexOf-int-
However, I think you just want to call NamedObj.getName():
parameter.getContainer().getName() should do the trick.

Dear Kepler folks,
In ActorReference.pdf file, there are explanations of each
actors. I have questions for this reference.
* I can see the class name next to an actor. For example,
String Constant (ptolemy.actor.lib.StringConst). The class
name must be unique (i.e., ptolemy.actor.lib.StringConst). If
so, is the last classname unique? In other words,
"StringConst" is also unique?
* I can see the value of "StringConst" in _container in
parameter class. How can I just extract only last name
"StringConst"? Actually, I have tried several ways in
SQLRecording.java like below:
o System.out.println("3: " +
parameter.getContainer().toplevel().toString());
o System.out.println("4: " +
parameter.getContainer().getClassName());
o System.out.println("5: " + parameter.getContainer());
The output is :
o 3: ptolemy.actor.TypedCompositeActor {.Unnamed1}
o 4: ptolemy.actor.lib.StringConst
o 5: ptolemy.actor.lib.StringConst {.Unnamed1.DonghoonConstant}
Please, let me know
Thank you
