add getUnsigned() and putUnsigned() methods. #574

add getUnsigned() and putUnsigned() methods to get the correct unsigned integer value directly.

saudet commented 2 years ago

Maybe we also want to add getUnsignedShort(), getUnsignedInt() etc while we're at it? Or are you OK with just bytes for now?

before31 commented 2 years ago

When you say getUnsignedInt(), you mean:

I need to get the next FOUR bytes and combine them into an integer? or,
I get the next ONE byte and operate '& 0xFF' to convert it to an unsigned integer(0-255)?

In my getUnsigned() implementation, it is the later one. The getUnsigned method actually returns a integer value in the range 0-255, and my need is that.

saudet commented 2 years ago

Your getUnsigned() is fine, I'm talking about 16, 32, and 64-bit values. You're never going to need those?

before31 commented 2 years ago

So far, I may not need those.
