public final class ArabicShaping
extends Object
```
Shape Arabic text on a character basis.
ArabicShaping performs basic operations for "shaping" Arabic text. It is most useful for use with legacy data formats and legacy display technology (simple terminals). All operations are performed on Unicode characters.

Text-based shaping means that some character code points in the text are replaced by others depending on the context. It transforms one kind of text into another. In comparison, modern displays for Arabic text select appropriate, context-dependent font glyphs for each text element, which means that they transform text into a glyph vector.

Text transformations are necessary when modern display technology is not available or when text needs to be transformed to or from legacy formats that use "shaped" characters. Since the Arabic script is cursive, connecting adjacent letters to each other, computers select images for each letter based on the surrounding letters. This usually results in four images per Arabic letter: initial, middle, final, and isolated forms. In Unicode, on the other hand, letters are normally stored abstract, and a display system is expected to select the necessary glyphs. (This makes searching and other text processing easier because the same letter has only one code.) It is possible to mimic this with text transformations because there are characters in Unicode that are rendered as letters with a specific shape (or cursive connectivity). They were included for interoperability with legacy systems and codepages, and for unsophisticated display systems.

A second kind of text transformations is supported for Arabic digits: For compatibility with legacy codepages that only include European digits, it is possible to replace one set of digits by another, changing the character code points. These operations can be performed for either Arabic-Indic Digits (U+0660...U+0669) or Eastern (Extended) Arabic-Indic digits (U+06f0...U+06f9).

Some replacements may result in more or fewer characters (code points). By default, this means that the destination buffer may receive text with a length different from the source length. Some legacy systems rely on the length of the text to be constant. They expect extra spaces to be added or consumed either next to the affected character or at the end of the text.

Status:
Stable ICU 2.0.

    Construct ArabicShaping using the options flags. The flags are as follows:
    'LENGTH' flags control whether the text can change size, and if not, how to maintain the size of the text when LamAlef ligatures are formed or broken.
    'TEXT_DIRECTION' flags control whether the text is read and written in visual order or in logical order.
    'LETTERS_SHAPE' flags control whether conversion is to or from presentation forms.
    'DIGITS' flags control whether digits are shaped, and whether from European to Arabic-Indic or vice-versa.
    'DIGIT_TYPE' flags control whether standard or extended Arabic-Indic digits are used when performing digit conversion.

    Parameters:
    
    source - An array containing the input text
    
    sourceStart - The start of the range of text to convert
    
    sourceLength - The length of the range of text to convert
    
    dest - The destination array that will receive the result. It may be NULL only if destSize is 0.
    
    destStart - The start of the range of the destination buffer to use.
    
    destSize - The size (capacity) of the destination buffer. If destSize is 0, then no output is produced, but the necessary buffer size is returned ("preflighting"). This does not validate the text against the options, for example, if letters are being unshaped, and spaces are being consumed following lamalef, this will not detect a lamalef without a corresponding space. An error will be thrown when the actual conversion is attempted.
    
    Returns:
    
    The number of chars written to the destination buffer. If an error occurs, then no output was written, or it may be incomplete.
    
    Throws:
    
    ArabicShapingException - if the text cannot be converted according to the options.
    
    Status:
    Stable ICU 2.0.
  - shape
```
public void shape(char[] source,
                  int start,
                  int length)
           throws ArabicShapingException
```
    Convert a range of text in place. This may only be used if the Length option does not grow or shrink the text.
    
    Parameters:
    
    source - An array containing the input text
    
    start - The start of the range of text to convert
    
    length - The length of the range of text to convert
    
    Throws:
    
    ArabicShapingException - if the text cannot be converted according to the options.
    
    Status:
    Stable ICU 2.0.
  - shape
```
public String shape(String text)
             throws ArabicShapingException
```
    Convert a string, returning the new string.
    
    Parameters:
    
    text - the string to convert
    
    Returns:
    
    the converted string
    
    Throws:
    
    ArabicShapingException - if the string cannot be converted according to the options.
    
    Status:
    Stable ICU 2.0.

```
public boolean equals(Object rhs)
```
    Overrides:
    
    equals in class Object

  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
    
    Status:
