      implements
      
        InputFilter
      
  
  
  
    
  This filter will capitalize all the lowercase and titlecase letters that are added
 through edits. (Note that if there are no lowercase or titlecase letters in the input, the
 text would not be transformed, even if the result of capitalization of the string is
 different from the string.)

Public methods
    filter
    
public CharSequence filter (CharSequence source, 
                int start, 
                int end, 
                Spanned dest, 
                int dstart, 
                int dend)
    
    
    
  This method is called when the buffer is going to replace the
 range dstart … dend of dest
 with the new text from the range start … end
 of source.  Return the CharSequence that you would
 like to have placed there instead, including an empty string
 if appropriate, or null to accept the original
 replacement.  Be careful to not to reject 0-length replacements,
 as this is what happens when you delete text.  Also beware that
 you should not attempt to make any changes to dest
 from this method; you may only examine it for context.
 Note: If source is an instance of Spanned or
 Spannable, the span objects in the source should be
 copied into the filtered result (i.e. the non-null return value).
 TextUtils.copySpansFrom can be used for convenience if the
 span boundary indices would be remaining identical relative to the source.
