func GetOrSetFuncLock

func GetOrSetFuncLock(name string, f func() interface{}) interface{}

GetOrSetFuncLock returns the instance by name, or sets instance with returned value of callback function <f> if it does not exist and then returns this instance.

GetOrSetFuncLock differs with GetOrSetFunc function is that it executes function <f> with mutex.Lock of the hash map.
