  - by user330352

  Hi all, in C++, when you define a function which takes one argument, you have to define the data type of that variable: void makeProccess(int request) However, I want to implement a function which takes different data types rather taking statically defined integer type. void makeProccess(anyType request) How can I design a proccess like this, any idea? Thanks.

  My goal is to write this: println "this should be 3: ($1+2)" //this is invalid groovy, it won't run Yet this is valid in ruby.

• What kind of data type is this?

  - by mystify

  In an class header I have seen something like this: enum { kAudioSessionProperty_PreferredHardwareSampleRate = 'hwsr', // Float64 kAudioSessionProperty_PreferredHardwareIOBufferDuration = 'iobd' // Float32 }; Now I wonder what data type such an kAudioSessionProperty_PreferredHardwareSampleRate actually is? I mean this looks like plain old C, but in Objective-C I would write @"hwsr" if I wanted to make it a string. I want to pass such an "constant" or "enum thing" as argument to an method.

• How do i pass null into stdin like this perl code?

• How is the result of openssl_sign() encoded?

  - by Bozho

  The docs about openssl_sign() say that the signature is returned in the passed string argument. My question is - how is it encoded? Base64, Hex-string, anything else? I don't have php installed and I have to use this PHP code I was given simply in order to verify whether my Java implementation is correct, so don't ask me "have you tried it" ;)

• regarding object recycling

  - by ajaycv

  I have a question. What is wrong with regards to the below code: ArrayList tempList2 = new ArrayList(); tempList2 = getXYZ(tempList1, tempList2); //method getXYZ getXYZ(ArrayList tempList1, ArrayList tempList2) { //does some logic and adds objects into tempList2 return tempList2; } The code will get executed but it seems by passing tempList2 to the getXYZ method argument, it is doing object recycling. My question is, Is recycling the tempList2 arraylist object correct?
