  - frozen
```
@NotNull
default CharIndexable frozen()
```
    Get a frozen version of this indexable.
    Often Indexables are used as a view to underlying collections. Although this interface is immutable, the underlying colelction might nevertheless change. This copies the current state of this indexable into an unmodifiable state, and returns an Indexable which is stable in size and will return always the same element for a given index. Beware: it is still possible that any element itself changes when the elements are mutable.
    Calling frozen() again on the returned object will just return the object itself, so you can safely call this method more than once.
    
    Returns:
    
    frozen version of this Indexable

    Is this indexable sorted according to the given ordering? This method tests that consecutive elements in this indexable or either ascending or the same, but never descending. See isStrictlyOrdered(CharOrdering) for a stricter alternative.
    
    Parameters:
    
    order - expected ordering
    
    Returns:
    
    true if this indexable is sorted as defined by order
    false if not
  - isOrdered
```
default boolean isOrdered()
```
    Is this indexable sorted naturally? This method tests that consecutive elements in this indexable or either ascending or the same, but never descending.
    See isStrictlyOrdered() for a stricter alternative.
    
    Returns:

```
    Is this indexable strictly sorted according to the given ordering? This method tests that consecutive elements in this indexable or strictly ascending or the same, but never descending. See isOrdered(CharOrdering) for a more relaxed alternative.
    Prefer isOrdered() to check for natural ordering because it is faster.
    
    Parameters:
    
    order - expected ordering
    
    Returns:
    
    true if this indexable is sorted as defined by order

    false if not
  - binarySearch
```
default int binarySearch(char value)
```
    Do a binary search in an indexable ordered in natural ascending order. This requires this indexable to be ordered in natural ascending order, i.e. isOrdered(CharOrdering) has to return true for this ordering. For efficiency this prerequisite is not checked, but not fulfilling it will make this method return bogus results. If this indexable is only ordered, but not strictly ordered it is not defined which index is returned when the looked up value appears in a sequence of equal values.
    
    Parameters:
    
    value - value to look up
    
    Returns:
    
    a positive integer defining the index where the given value was found, and a negative integer if the value is not contained. The latter defines the insertion point where the looked up value would match into this sorted indexable in the form -(insertIndex + 1).
  - binarySearch
```

                         @NotNull
                         CharOrdering order)
```
    Do a binary search in an ordered indexable. This requires this indexable to be ordered in non-descending order as defined by the given order, i.e. isOrdered(CharOrdering) has to return true for this order. For efficiency this prerequisite is not checked, but not fulfilling it will make this method return bogus results. If this indexable is only ordered, but not strictly ordered it is not defined which index is returned when the looked up value appears in a sequence of equal values.
    
    Parameters:
    
    value - value to look up
    
    order - sort order
    
    Returns:
    
    a positive integer defining the index where the given value was found, and a negative integer if the value is not contained. The latter defines the insertion point where the looked up value would match into this sorted indexable in the form -(insertIndex + 1).

```
    Create a view of this char indexable with an inserted value. Note that this is not efficient, but handy in certain situations where only 1 or a few values are inserted. Use ExpandableIntIndexable if you want to carry out more stuff like this.
    As this creates a view of this indexable, changes to this indexable might result in a disaster when using the returned indexable!
    
    Parameters:
    
    index - index where the value is inserted before the current index (not Pythonesque, because it is possible to add an value at index == size(), and it is expected that most insertion will happen at 0 or at the end)
    
    value - inserted value at that index
    
    Returns:
    
    a view of this indexable with 1 more value at the given index, all values beyond are moved one index forward
    
    See Also:
    
    withAppendedValue(char)

```
@NotNull
default CharIndexable withAppendedValue(char value)

    Create a view with of this indexable with another value added at the end. Note that this is not efficient, but handy in certain situations where only 1 or a few items are added.
    
    Parameters:
    
    value - value to add
    
    Returns:
    
    indexable view of this indexable, with the given value added at the end, so size is larger by 1

```
    Create a view of this char indexable with an exchanged value. Note that this is not efficient, but handy in certain situations where only 1 or a few values are exchanged. Use ExpandableIntIndexable if you want to carry out more stuff like this.
    As this creates a view of this indexable, changes to this indexable could lead to unexpected results when using the returned indexable!
    
    Parameters:
    
    index - index where the element is exchanged, hiding the current element. (Pythonesque)
    
    value - exchanged value at that index
    
    Returns:
    
    a view of this indexable with 1 more element at the given index, all elements beyond are moved one index forward
  - withRemovedValueAt
```
@NotNull
default CharIndexable withRemovedValueAt(int index)

    Parameters:
    
    index - index of the removed value (Pythonesque)
    
    Returns:
    
    a view of this indexable where the value at the given index is removed

```
    Create a view of this char indexable with two values swapped. Note that this is not efficient, but handy in certain situations where only a few items are swapped.
    
    Parameters:
    
    index1 - index of the first value (Pythonesque)
    
    index2 - index of the second value (Pythonesque)
    
    Returns:
    
    a view of this indexable where the first and second value have exchanged places
  - rotated
```
@NotNull
default CharIndexable rotated(int steps)
```
    Get a rotated view of this char indexable. The returned indexable will show this indexable with rotated indexes. A positive steps will rotate left, i.e. any index will be accessed as if the number of steps is added before extraction (modulo length). E.g. a rotation of -1 will return the last element when index 0 is requested, and the first element for index 1.
    
    Parameters:
    
    steps - steps to rotate
    
    Returns:
    
    rotated view of this indexable, use frozen() to create an indexable which no longer depends on this one

```
    View this indexable as a boolean indexable while using a conversion for each value.
    Use frozen() on the result to decouple it from this indexable.
    
    Parameters:
    
    convert - converter applied to each value of this indexable before it is returned from the resulting indexable
    
    Returns:
    
    boolean indexable view of this indexable
  - toText
```
@NotNull
default java.lang.String toText()
```
    Create a string representation of this char indexable. Compared to () this method will always work, toString() will only do what is expected when the implementation extends CharIndexable.Base (which takes care of toString() or provides the expected implementation itself.
    Use asCharSequence() to create a non-copy view of this char indexable, and use subSet(int, int), headSet(int), or tailSet(int) first to create texts from parts of this indexable.
    
    Returns:
    
    a string created from the characters in this char indexable
    
    See Also:
    
    asCharSequence()
  - asCharSequence
```
@NotNull
default java.lang.CharSequence asCharSequence()
```
    Get a view of this char indexable as a char sequence.
    The main advantage over Object.toString() is that this method will always work even if the implementation of this interface is neither extending CharIndexable.Base nor takes care of creating a string itself, and that this method does not copy the chars around which can be preferable for large sizes.
    
    Returns:
    
    char sequence view, i.e. any changes to this char indexable will be reflected in the view. Use frozen() for an immutable char indexable first if this might create a problem.

```
    Compare two char indexables. This compares the two indexable lexically element by element until either the first difference is found (smaller of the two values define the lower indexable) or the end of one is met (shorter indexable is less).
    
    Parameters:
    
    indexable1 - first indexable
    
    indexable2 - second indexable
    
    Returns:
