  - convert
```
public static String convert(byte[] data)
```
    convert outputs a byte oid in a hex string dump formatted like e.g.: 49 6d 52 ImR ....
    
    Parameters:
    data - a byte value
    
    Returns:
    a String value
  - convert
```
public static String convert(Policy policy,
             int policy_type)
```
    reads the policy value from the specified policy and converts it into a string
  - convert
```
public static String convert(State state)
```
    converts the state into a string
  - extractImplName
```
public static String extractImplName(byte[] object_key)
```
    extracts the impl name from a specified object key
  - extractOID
```
public static byte[] extractOID(byte[] object_key)
```
    extracts the oid from a specified object key
  - extractOID
```
public static byte[] extractOID(Object reference)
```
    extracts the oid from a specified object reference
  - extractPOAName
```
public static String extractPOAName(byte[] object_key)
```
    extracts the poa name from a specified object key
  - extractScopedPOANames
```
public static List<String> extractScopedPOANames(String poa_name)
```
    extractScopedPOANames returns a list containing the poa_names. This method is faster than using a StringTokenizer.
    
    Parameters:
    poa_name - is a String value which may contain poa_names separated by OBJECT_KEY_SEPARATOR
    
    Returns:
    a Vector value
  - getPolicy
```
public static Policy getPolicy(Policy[] policies,
               int policy_type)
```
    returns the policy with the specified policy_type from a policy list
  - isActive
```
public static boolean isActive(State state)
```
  - isDiscarding
```
public static boolean isDiscarding(State state)
```
  - isHolding
```
public static boolean isHolding(State state)
```
  - isInactive
```
public static boolean isInactive(State state)
```
  - maskId
```
public static byte[] maskId(byte[] id)
```
    masks the object key separator bytes
  - maskStr
```
public static String maskStr(String str)
```
    masks the object key separator chars
  - unmaskStr
```
public static String unmaskStr(String str)
```
    unmasks the object key separator chars
  - unmaskId
```
public static byte[] unmaskId(byte[] id)
```
    unmasks the object key separator bytes
  - toHex
```
public static final String toHex(byte b)
```
    toHex converts a byte into a readable string.
    
    Parameters:
    b - a byte value
    
    Returns:
    a String value
