dnl


dnl Get:


dnl Creates accessors for simple types:
dnl _MEMBER_GET(cpp_name, c_name, cpp_type, c_type, deprecated (optional))
define(`_MEMBER_GET',`dnl
ifelse(`$5',`deprecated',`_DEPRECATE_IFDEF_START  ')dnl
$3 get_$1() const;
ifelse(`$5',`deprecated',`_DEPRECATE_IFDEF_END  ')dnl
_PUSH(SECTION_CC)
ifelse(`$5',`deprecated',`_DEPRECATE_IFDEF_START  ')dnl
$3 __CPPNAME__::get_$1() const
{
  return _CONVERT($4,$3,`gobj()->$2');
}
ifelse(`$5',`deprecated',`_DEPRECATE_IFDEF_END  ')dnl

_POP()')

dnl Creates two accessors for pointer types, one const and one non-const:
define(`_MEMBER_GET_PTR',`dnl
ifelse(`$5',`deprecated',`_DEPRECATE_IFDEF_START  ')dnl
$3 get_$1();
  const $3 get_$1() const;
ifelse(`$5',`deprecated',`_DEPRECATE_IFDEF_END  ')dnl
_PUSH(SECTION_CC)
ifelse(`$5',`deprecated',`_DEPRECATE_IFDEF_START  ')dnl
$3 __CPPNAME__::get_$1()

const $3 __CPPNAME__::get_$1() const
{
  return _CONVERT($4,const $3,`gobj()->$2');
}
ifelse(`$5',`deprecated',`_DEPRECATE_IFDEF_END  ')dnl

_POP()')

dnl Creates accessors for GObject-derived types that must be ref()ed.
define(`_MEMBER_GET_GOBJECT',`dnl
ifelse(`$5',`deprecated',`_DEPRECATE_IFDEF_START  ')dnl
Glib::RefPtr<$3> get_$1();

Glib::RefPtr<$3> __CPPNAME__::get_$1()
{
  Glib::RefPtr<$3> ref_ptr(_CONVERT($4,Glib::RefPtr<$3>,`gobj()->$2'));

dnl We could use the bool with Glib::wrap(), but we want to share the m4 type-conversion map.
  if(ref_ptr)
    ref_ptr->reference();

  return ref_ptr;

dnl Set:

dnl Creates accessors for simple types:
define(`_MEMBER_SET',`dnl
ifelse(`$5',`deprecated',`_DEPRECATE_IFDEF_START  ')dnl

{
  gobj()->$2 = _CONVERT($3,$4,`value');
}
ifelse(`$5',`deprecated',`_DEPRECATE_IFDEF_END  ')dnl

_POP()')

dnl Creates setters for a member which is of char* type:
dnl The convenient way to use this macro is to pair it with
dnl _CONVERSION(`Glib::ustring', `const gchar*', `($3).c_str()')
dnl or similar conversion.
dnl There is no _MEMBER_GET_STR. With a suitable _CONVERSION,
dnl _MEMBER_GET can be used as the corresponding getter.
define(`_MEMBER_SET_STR',`dnl
ifelse(`$5',`deprecated',`_DEPRECATE_IFDEF_START  ')dnl

  gobj()->$2 = g_strdup(_CONVERT($3,$4,`value'));
}
ifelse(`$5',`deprecated',`_DEPRECATE_IFDEF_END  ')dnl

_POP()')

dnl Creates accessors for pointer types:
