I am looking to add a function to a program where I use static variables to create a list of all the times the driver has used the constructor, using names. What I need to know is this, is there a way, in java, to access what the reference variable is (as a string) to add it to the list? Pseudocode:
public ClassName
String static list = "";
Public ClassName (parameters){
list += getReferenceVariable();
}
The getReferenceVariable is what I'm asking if anyone knows a way to do that
If I understand you correctly, you want to keep a list of all the times the constructor was called, and save the names of the currently-being-created variable? Because the "Reference variable" is none when you use the constructor, since you call the constructor with a new MyClass(), and not some obj.MyClass().
If, however, you simply want to know who called you (As a stack trace is), you can simply, as written in this thread (no pun intended), use Thread.currentThread().getStackTrace(), and then choose the desired stack frame (Probably 2, since The first element (index 0) in the array is the java.lang.Thread.getStackTrace method, the second (index 1) is the constructor, and 2 is where the constructor was called from), where you can get (for example) the name of the source file that this stack trace corresponds to. Documentation of getFileName()
Since I haven't tried it on my end (not possible at the moment), I give you code to use with caution:
public class MyClass(){
MyClass(){
callerName = Thread.currentThread().getStackTrace()[2].getFileName();
... // anything here
}
}
