  This method does intentionally not use the pseudo-constructor naming pattern since it does not create new instances of String. Instead, it returns a constant instance of an intrinsic look-up table.

  public static final String upperCaseFirstChar(String s)
  
  Ensures that the first character of the passed String is in upper case.

  Parameters:
  
  s - the String for which the first character shall be ensured to be upper case.

- hashCode
  
  public static final int hashCode(char[] chars, int offset, int length)
  This method rebuilds the String hashing algorithm.
  Returns a hash code for the passed character range. The hash code is computed as
  s[0]*31^(n - 1) + s[1]*31^(n-2) + ... + s[n - 1]
  using int arithmetic, where s[i] is the ith character counted from the given offset, n is the length and ^ indicates exponentiation. The hash value of an empty range is zero.
  Parameters:
  
  chars - the character array
  
  offset - the start offset
  
  length - the length
  
  Returns:
  
  a hash code value for this object.

  length - the length
  
  Returns:
  
  the trimmed String
- trim
  
  public static String trim(String s)
  
  Calls String.trim() on a non-null argument, returns null otherwise. (this is nothing but a static String.trim())
  
  Parameters:
  
  s - the String instance to be trimmed, potentially null.
  
  Returns:
  
  a potentially null trimmed String instance.

- internalParse_longLiteral
  
  public static final long internalParse_longLiteral(char[] input, int offset, int length)
  
  Special case higher performance implementation of decimal integer literal parsing. Because as usual, the JDK implementation strategies are not acceptable when dealing with non-trivial amounts of data. Properly executed performance tests (large loop sizes, averages, nanosecond precision, etc.) showed that this algorithms is more than twice as fast as the one used in JDK (average of ~33µs vs ~75µs for long literals on same machine with measuring overhead of ~1.5µs)
  
  Parameters:
  
  input - the source char array
  
  offset - the start offset
  
  length - the length
  
  Returns:
  
  the parsed long value

- systemString
  
  public static String systemString(Object instance)
  
  Utility method that replicates the JVM's intrinsic system string as defined in Object.toString()
  
  Parameters:
  
  instance - the instance whose system string shall be generated.
  
  Returns:
  
  the system string for the passed instance.
- addSystemString
  
  public static VarString addSystemString(Object instance, VarString vs)
- nonNullString
  
  public static String nonNullString(Object object)
- valueString
  
  public static String valueString(Object value)
  
  Returns value.toString() if the passed value is not null, otherwise null.
  Note that this is a different behavior than String.valueOf(Object) has, as the latter returns the string "null" for a passed null reference.
  The behavior of this method is needed for example for converting values in a generic data structure (e.g. a Object[] array) to string values but have the actual values, including null (information about a missing value), maintained.
  
  Parameters:
  
  value - the value to be projected to its string representation if not null.
  
  Returns:
  
  a string representation of an actual passed value or a transient null.
  
  See Also:
  
  Object.toString(), String.valueOf(Object)
- trimEmptyToNull
  
  public static String trimEmptyToNull(String s)
- assembleCautiously
  
  public static final VarString assembleCautiously(VarString vs, Object object)
  
  Assembles the passed instance "cautiously" in the sense that only types recognizable via XTypes.isValueType(Object) get assembled using their Object.toString() method, while all others are assembled using systemString(Object) (which behaves identical to the actual implementation of Object.toString()).
  
  Parameters:
  
  vs - the VarString instance to hold the assembled string.
  
  object - the instance to be assembled "cautiously" as described above.
  
  Returns:
  
  the passed vs instance (method-chaining viable).
