Yes, this library uses Nested Vectored Interrupts (NVIC). If you go to the library page, you can look into the code (see PulseCounter.cpp).

If you know what you are searching for, I would recommend you to have a look into the user manual of your target platform. Go to the Platform page, select your target platform and you will find a link to the manual at the bottom of the page.

You can see in the source code it uses a hardware counter, however it does so on the LPC1768 and won't work on your platform.
