With the Extract Method refactoring, you can take a code fragment, move it into a separated method and replace the old code with a call to the method. If the code always exits in return statements (all execution paths lead to possibly implicit return statements), it is extracted as is. However, if it contains execution paths without returns, the extracted method will have an additional
bool flag as a
return value. The flag is used to perform an early return on the call side.
When you extract a function by using the Extract Method refactoring, GoLand keeps the original order of parameters of a parent function.
