```
public static ServerTimer[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (ServerTimer c : ServerTimer.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ServerTimer valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - getTimerName
```
public String getTimerName()
```
    Specified by:
    
    getTimerName in interface AbstractMetrics.Timer
  - isGlobal
```
public boolean isGlobal()
```
    Returns true if the timer is global (not attached to a particular resource)
    
    Specified by:
    
    isGlobal in interface AbstractMetrics.Timer
    
    Returns:
    
    true if the timer is global
