Is there a specified way to declare a method or a function to return void in JsDoc? Currently I am in the belief that void is the default return value, and other return values must be specifically provided:
/**
* @return {Integer} The identifier for ...
*/
Answer
Closure Compiler
According to the documentation of Google's Closure Compiler if nothing is being returned, the @return annotation should be omitted.
If there is no return value, do not use a @return tag.

jsdoc-toolkit
However further documentation also states that the returnType and returnDescription are optional parameters.
returnType - Optional: the type of the return value.
returnDescription - Optional: any additional description.

Summary
You could either leave out the return annotation or include it without any parameters.
