Class Inline

  • public final class Inline
extends Object
    This class converts tokens to a numeric value. The bytes of the inlined values are composed as follows: 
     - Byte 0-2: unused
 - Byte 3: see bit layout in DiskData.
 - Byte 4: integer value or inlined whitespace token
    XML 1.0 whitespaces will be represented as follows: 
     - 00: 0x0A (new line)
 - 01: 0x09 (tabulator)
 - 10: 0x20 (space)
 - 11: 0x0D (carriage return)
