public class ArabicScriptProcessor
extends DefaultScriptProcessor
```
The ArabicScriptProcessor class implements a script processor for performing glyph substitution and positioning operations on content associated with the Arabic script.

This work was originally authored by Glenn Adams (gadams@apache.org).

  - getSubstitutionFeatures
```
public java.lang.String[] getSubstitutionFeatures()
```
    Obtain script specific required substitution features.
    
    Overrides:
    
    getSubstitutionFeatures in class DefaultScriptProcessor
    
    Returns:
    
    array of suppported substitution features or null
  - getSubstitutionContextTester
```
public ScriptContextTester getSubstitutionContextTester()
```
    Obtain script specific substitution context tester.
    
    Overrides:
    
    getSubstitutionContextTester in class DefaultScriptProcessor
    
    Returns:
    
    substitution context tester or null
  - getPositioningFeatures
```
public java.lang.String[] getPositioningFeatures()
```
    Obtain script specific required positioning features.
    
    Overrides:
    
    getPositioningFeatures in class DefaultScriptProcessor
    
    Returns:
    
    array of suppported positioning features or null
  - getPositioningContextTester
```
public ScriptContextTester getPositioningContextTester()
```
    Obtain script specific positioning context tester.
    
    Overrides:
    
    getPositioningContextTester in class DefaultScriptProcessor
    
    Returns:
    
    positioning context tester or null
  - reorderCombiningMarks
```
public GlyphSequence reorderCombiningMarks(GlyphDefinitionTable gdef,
                                           GlyphSequence gs,
                                           int[] widths,
                                           int[][] gpa,
                                           java.lang.String script,
                                           java.lang.String language)
```
    Reorder combining marks in glyph sequence so that they precede (within the sequence) the base character to which they are applied. N.B. In the case of RTL segments, marks are not reordered by this, method since when the segment is reversed by BIDI processing, marks are automatically reordered to precede their base glyph.
    
    Overrides:
    
    reorderCombiningMarks in class DefaultScriptProcessor
    
    Parameters:
    
    gdef - the glyph definition table that applies
    
    gs - an input glyph sequence
    
    widths - associated unscaled advance widths (also reordered)
    
    gpa - associated glyph position adjustments (also reordered)
    
    script - a script identifier
    
    language - a language identifier
    
    Returns:
    
    the reordered (output) glyph sequence
