public TF32J()
```
- Method Detail
  - main
```
public static void main(java.lang.String[] args)
```
  - invoke
```
public void invoke(java.lang.String cname,
                   java.lang.String mname)
```
    Parameters:
    
    cname - Class name -- constructor that takes reference to this class (TF32J)
    
    mname - Method name -- name of a null-argument method in that class
    Used for calling methods operating on WaveSourceJ objects in myjava\ModDemod.java for purposes of implementing modulators, demodulators or other signal processing implemented as a graph of single-input single-output filters.
    Uses a Java Classloader of directory myjava relative to the current directory to allow modifying and recompiling cname.mname without having to exit TF32J and restart it to get the changes. Directory myjava must not be on the Java classpath used in launching TF32J/TF32JMod, otherwise this "trick" will not work.
    Uses Java "reflection" to link to cname.mname at runtime -- this becomes flexible like Python but also with the limitation of Python of no compile-time checking hence the use of Exceptions to flag a runtime error. This feature implements "duck typing" (if it looks like a duck and quacks like a duck) to invoke a method on any object, regardless of its statically compiled type if its name matches the supplied string and if its "signature" (pattern of supplied arguments) matches the specified template.
