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