```
public IRichSequenceBase(int hash)
```
    Constructor with pre-computed hash if available, 0 for lazy computation if length() not 0
    NOTE: the hash code computed for this class is equivalent to the string hash of the same characters to ensure that equals can use the hash code for quick failure. CharSequence hash code is not specified therefore when in doubt about how it is computed then 0 should be passed to this constructor to compute one that is equal to the string content.
    
    Parameters:
    
    hash - hash code for the char sequence.

  - equals

    Description copied from interface: IRichSequence
    
    All index methods return the position or -1 if not found of the given character, characters or string.
    The basic methods have overloads for 1, 2, or 3 characters and CharSequence parameters. If fromIndex is not given then for forward searching methods 0 is taken as the value, for reverse searching methods length() is taken as the value
    For forward searching methods fromIndex is the minimum start position for search and endIndex is the maximum end position, if not given the length() of string is assumed.
    For reverse searching methods fromIndex is the maximum start position for search and startIndex is the minimum end position, if not given then 0 is assumed.

```
    Description copied from interface: IRichSequence
    
    Count leading/trailing characters of this sequence
    Parameters can be CharPredicate, counts any contiguous leading/trailing characters in the sequence which are contained in the given char set.
    All functions have overloads: with no fromIndex then 0 is taken for leading and length() for trailing methods with fromIndex then this is taken as the start for leading and end for trailing methods with fromIndex and endIndex, counting will start at fromIndex and stop at endIndex
    countLeading(CharPredicate): count contiguous leading characters from set in this sequence countLeadingNot(CharPredicate): count contiguous leading characters not from set in this sequence countTrailing(CharPredicate): count contiguous leading characters from set in this sequence countTrailingNot(CharPredicate): count contiguous leading characters not from set in this sequence
    
    Specified by:
    
    countLeading in interface IRichSequence<T extends IRichSequence<T>>
    
    Parameters:
    
    chars - predicate for set of contiguous characters which should be counted
    
    Returns:
    
    number of chars in contiguous span at start of sequence
