LocalUEnumerationPointer
"Smart pointer" class, closes a UEnumeration via uenum_close().
icu::StringEnumeration
Base class for 'pure' C++ implementations of uenum api.
Definition strenum.h:61
localpointer.h
C++ API: "Smart pointers" for use with and in ICU4C C++ code.
U_DEFINE_LOCAL_OPEN_POINTER
#define U_DEFINE_LOCAL_OPEN_POINTER(LocalPointerClassName, Type, closeFunction)
"Smart pointer" definition macro, deletes objects via the closeFunction.
Definition localpointer.h:550
uenum_count
U_CAPI int32_t uenum_count(UEnumeration *en, UErrorCode *status)
Returns the number of elements that the iterator traverses.
uenum_openCharStringsEnumeration
U_CAPI UEnumeration * uenum_openCharStringsEnumeration(const char *const strings[], int32_t count, UErrorCode *ec)
Given an array of const char* strings (invariant chars only), return a UEnumeration.
uenum_openUCharStringsEnumeration
U_CAPI UEnumeration * uenum_openUCharStringsEnumeration(const UChar *const strings[], int32_t count, UErrorCode *ec)
Given an array of const UChar* strings, return a UEnumeration.
UEnumeration
struct UEnumeration UEnumeration
structure representing an enumeration object instance
Definition uenum.h:44
uenum_reset
U_CAPI void uenum_reset(UEnumeration *en, UErrorCode *status)
Resets the iterator to the current list of service IDs.
uenum_unext
U_CAPI const UChar * uenum_unext(UEnumeration *en, int32_t *resultLength, UErrorCode *status)
Returns the next element in the iterator's list.
uenum_next
U_CAPI const char * uenum_next(UEnumeration *en, int32_t *resultLength, UErrorCode *status)
Returns the next element in the iterator's list.
uenum_openFromStringEnumeration
U_CAPI UEnumeration * uenum_openFromStringEnumeration(icu::StringEnumeration *adopted, UErrorCode *ec)
Given a StringEnumeration, wrap it in a UEnumeration.
uenum_close
U_CAPI void uenum_close(UEnumeration *en)
Disposes of resources in use by the iterator.
U_CAPI
#define U_CAPI
This is used to declare a function as a public ICU C API.
Definition umachine.h:110
UChar
char16_t UChar
The base type for UTF-16 code units and pointers.
Definition umachine.h:378
utypes.h
Basic definitions for ICU, for both C and C++ APIs.
UErrorCode
UErrorCode
Standard ICU4C error code type, a substitute for exceptions.
Definition utypes.h:430
