How to change the value of a variable during debugging in IntelliJ so that the corresponding clock is automatically updated?

Question

I have the following code snippet:

Matcher matchDays = m_daysRegex.matcher(e.getKey()); if (matchDays.matches()){ ... } 

Where e.getKey() is Mon-Fri.

Now I have already completed the first line and inserted the if statement. Using the viewport, I evaluate the expression matchDays.matches() , and then add some hours for the various matchDays methods. Then, using the same viewport, I evaluate the matchDays = m_daysRegex.matcher("Mon,Fri") and matchDays.matches() to see what happens. Unfortunately, the viewport does not update, and it does not have an explicit button for this:

In the image above, notice how matchDays.group(0) displays "Mon, Fri," but matchDays.group(1) displays "Mon-Fri." This is because I manually updated the first, but everyone else still shows the old values. I have to manually update them all, which is annoying.

Am I doing something wrong? Is there a proper way to do this, so that the clock expressions are updated automatically? Or is there a way to refresh the entire viewport?

Thanks.

Answer 1

This is how I changed the value of a variable at runtime in Intelij

• Variables are displayed in the Variables window.
• Right click and select value
• Update the value and press the enter key.

Answer 2

It is not possible to update them automatically, because updating will require calling the actual methods, which may have side effects for the debugger and application semantics. Simple clock values ​​are updated automatically.
