public class CMapStrings extends Object

Many CMaps are using the same values for the mapped strings. This class provides all common one- and two-byte mappings to avoid duplicate strings.

Method Details
- getMapping
  
  public static String getMapping(byte[] bytes)
  
  Get the mapped string value for the given combination of bytes. The mapping is limited to one and two-byte mappings. Any longer byte sequence produces null as return value.
  
  Parameters:
  
  bytes - the given combination of bytes
  
  Returns:
  
  the string representation for the given combination of bytes
- getIndexValue
  
  public static Integer getIndexValue(byte[] bytes)
  
  Get an Integer instance of the given combination of bytes. Each value is a singleton to avoid multiple instances for same value. The values are limited to one and two-byte sequences. Any longer byte sequence produces null as return value.
  
  Parameters:
  
  bytes - the given combination of bytes
  
  Returns:
  
  the Integer representation for the given combination of bytes
- getByteValue
  
  public static byte[] getByteValue(byte[] bytes)
  
  Get a singleton instance of the given combination of bytes to avoid multiple instances for same value. The values are limited to one and two-byte sequences. Any longer byte sequence produces null as return value.
  
  Parameters:
  
  bytes - the given combination of bytes
  
  Returns:
  
  a singleton instance for the given combination of bytes
