uenum_close
void uenum_close(UEnumeration *en)
Disposes of resources in use by the iterator.
uenum_openUCharStringsEnumeration
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:43
icu::StringEnumeration
Base class for &#39;pure&#39; C++ implementations of uenum api.
Definition: strenum.h:57
uenum_next
const char * uenum_next(UEnumeration *en, int32_t *resultLength, UErrorCode *status)
Returns the next element in the iterator&#39;s list.
U_NAMESPACE_BEGIN
#define U_NAMESPACE_BEGIN
This is used to begin a declaration of a public ICU C++ API.
Definition: uversion.h:131
uenum_unext
const UChar * uenum_unext(UEnumeration *en, int32_t *resultLength, UErrorCode *status)
Returns the next element in the iterator&#39;s list.
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:487
localpointer.h
C++ API: "Smart pointers" for use with and in ICU4C C++ code.
uenum_count
int32_t uenum_count(UEnumeration *en, UErrorCode *status)
Returns the number of elements that the iterator traverses.
uenum_openCharStringsEnumeration
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.
UChar
uint16_t UChar
The base type for UTF-16 code units and pointers.
Definition: umachine.h:349
U_NAMESPACE_END
#define U_NAMESPACE_END
This is used to end a declaration of a public ICU C++ API.
Definition: uversion.h:132
UErrorCode
UErrorCode
Error code to replace exception handling, so that the code is compatible with all C++ compilers...
Definition: utypes.h:396
utypes.h
Basic definitions for ICU, for both C and C++ APIs.
LocalUEnumerationPointer
"Smart pointer" class, closes a UEnumeration via uenum_close().
uenum_reset
void uenum_reset(UEnumeration *en, UErrorCode *status)
Resets the iterator to the current list of service IDs.
uenum_openFromStringEnumeration
UEnumeration * uenum_openFromStringEnumeration(icu::StringEnumeration *adopted, UErrorCode *ec)
Given a StringEnumeration, wrap it in a UEnumeration.
U_STABLE
#define U_STABLE
This is used to declare a function as a stable public ICU C API.
Definition: umachine.h:111
