GetKeys method

The GetKeys method of the Dictionary class is shown in the following code snippet. The method returns the array of the DictKey elements. The RLock method of the lock instance is invoked, and the RUnlock method is deferred. The dictionary keys are returned by traversing the element's map:

// GetKeys methodfunc (dict *Dictionary) GetKeys() []DictKey {    dict.lock.RLock()    defer dict.lock.RUnlock()    var dictKeys []DictKey    dictKeys = []DictKey{}    var key DictKey    for key = range dict.elements {        dictKeys = append(dictKeys, key)    }    return dictKeys}
