  15 To add a new enum type
  16       (For example: UShoeSize  with values USHOE_WIDE=0, USHOE_REGULAR, USHOE_NARROW, USHOE_COUNT)
  17
  18     1. udbgutil.h:  add  UDBG_UShoeSize to the UDebugEnumType enum before UDBG_ENUM_COUNT
  19       ( The subsequent steps involve this file, udbgutil.cpp )
  20     2. Find the marker "Add new enum types above this line"
  21     3. Before that marker, add a #include of any header file you need.
  22     4. Each enum type has three things in this section:  a #define, a count_, and an array of Fields.
  23        It may help to copy and paste a previous definition.
  24     5. In the case of the USHOE_... strings above, "USHOE_" is common to all values- six characters
  25          " #define LEN_USHOE 6 "
  26        6 characters will strip off "USHOE_" leaving enum values of WIDE, REGULAR, and NARROW.
  27     6. Define the 'count_' variable, with the number of enum values. If the enum has a _MAX or _COUNT value,
  28         that can be helpful for automatically defining the count. Otherwise define it manually.
  29         " static const int32_t count_UShoeSize = USHOE_COUNT; "
  30     7. Define the field names, in order.
  31         " static const Field names_UShoeSize[] =  {
  32         "  FIELD_NAME_STR( LEN_USHOE, USHOE_WIDE ),
  33         "  FIELD_NAME_STR( LEN_USHOE, USHOE_REGULAR ),
  34         "  FIELD_NAME_STR( LEN_USHOE, USHOE_NARROW ),
  35         " };
  36       ( The following command  was usedfor converting ucol.h into partially correct entities )
  37       grep "^[  ]*UCOL" < unicode/ucol.h  |
  38          sed -e 's%^[  ]*\([A-Z]*\)_\([A-Z_]*\).*%   FIELD_NAME_STR( LEN_\1, \1_\2 ),%g'
  39     8. Now, a bit farther down, add the name of the enum itself to the end of names_UDebugEnumType
  40           ( UDebugEnumType is an enum, too!)
  41         names_UDebugEnumType[] { ...
  42             " FIELD_NAME_STR( LEN_UDBG, UDBG_UShoeSize ),   "
  43     9. Find the function _udbg_enumCount  and add the count macro:
  44             " COUNT_CASE(UShoeSize)
  45    10. Find the function _udbg_enumFields  and add the field macro:
  46             " FIELD_CASE(UShoeSize)
  47    11. verify that your test code, and Java data generation, works properly.
