Naming suggestion for a method - checkSignature or isSignatureValid or something else?

I have a method that checks the signature of a request is valid.

The method returns a boolean:

_ true: valid signature

_ false: signature is not valid

I am not sure about the best name for it (maybe also because I am not an English native spe开发者_JAVA百科aker).

I am not sure among:

_ checkSignature

_ isSignatureValid

Which one do you think is better and why or maybe you have a better suggestion.

Thanks,

Dan

isSignatureValid( ... ). It tells you what the method is going to return, which is nice. Also, it doesn't make a promise one way or another as far as caching goes (checkSignature implies to me that you will do all the math to check the signature when I call it, and you might not need to repeat all that work).

I prefer

hasValidSignature()

since isSignatureValid() doesn't semantically make sense because the request isn't a signature, it has a signature. I suppose you're going to be using this in an if statement so doesn't this make more sense?

if (request.hasValidSignature()) {
    ...
}

Furthermore, if you want to check if request is valid itself, then this would be more appropriate

if (request.isValid()) {
    ...
}
