public static boolean userNodeExists(Class<?> pClass,
                                     String... pKeys)

Determines whether user node exists for the specified class and keys.

userNodeExists
```
public static boolean userNodeExists(String pNodeName)
```
Determines whether user node exists for the specified absolute path name of node.

public static boolean systemNodeExists(Class<?> pClass,
                                       String... pKeys)

systemNodeExists
```
public static boolean systemNodeExists(String pNodeName)
```
Determines whether user node exists for the specified absolute path name of node.

public static String getNodeName(Class<?> pClass,
                                 String... pKeys)

Returns the absolute path name of the node corresponding to the specified class and keys.

getScreenConfigString
```
public static String getScreenConfigString()
```
Get a string that uniquely identifies a monitor configuration. If monitor count or resolution change, a different String will be returned.

shrinkKey
```
public static String shrinkKey(String pKey)
