Find all usages of toString() method

Question

I have a huge project with a class that is widely used everywhere inside this project. This class defines toString() method which outputs a lot of information. I want to define another method, say, toShortString() and replace all of the occurrences where original toString() is called with this method call.

The problem is that there is a lot of code that looks like follows:

log.debug("Order issued: " + order);
log.debug("Loaded list of orders: " + orders);

where order is instance of this object and orders is a list of such objects.

Is there any way to find all such occurrences?

Any suggestions are welcome. IDE is IntelliJ Idea, if it matters.

Answer 1

Instead of replacing all the occurences of toString() which would be error prone (you would definitely miss some) and some really difficult to replace (for example, the System.out.println() on a List of Order objects would always invoke toString() only) I suggest you modify the toString() itself to call toShortString().

Move all the code inside toString() to another function called toLongString() and then use this function where you feel the need to have a detailed String representation of Order objects.
