Abstract class that defines an API for iteration on text objects.
The CollationElementIterator class is used as an iterator to walk through each character of an inte...
UBool operator!=(const CollationElementIterator &other) const
Returns true if "other" is not the same as "this".
static UClassID getStaticClassID()
ICU "poor man's RTTI", returns a UClassID for this class.
int32_t strengthOrder(int32_t order) const
Gets the comparison order in the desired strength.
const UCollationElements * toUCollationElements() const
void reset(void)
Resets the cursor to the beginning of the string.
int32_t previous(UErrorCode &status)
Get the ordering priority of the previous collation element in the string.
UBool operator==(const CollationElementIterator &other) const
Returns true if "other" is the same as "this".
static CollationElementIterator * fromUCollationElements(UCollationElements *uc)
UCollationElements * toUCollationElements()
void setText(CharacterIterator &str, UErrorCode &status)
Sets the source string.
static const CollationElementIterator * fromUCollationElements(const UCollationElements *uc)
CollationElementIterator(const CollationElementIterator &other)
Copy constructor.
void setText(const UnicodeString &str, UErrorCode &status)
Sets the source string.
virtual UClassID getDynamicClassID() const
ICU "poor man's RTTI", returns a UClassID for the actual class.
int32_t getMaxExpansion(int32_t order) const
Return the maximum length of any expansion sequences that end with the specified comparison order.
int32_t next(UErrorCode &status)
Gets the ordering priority of the next character in the string.
int32_t getOffset(void) const
Gets the offset of the currently processed character in the source string.
void setOffset(int32_t newOffset, UErrorCode &status)
Sets the offset of the currently processed character in the source string.
virtual ~CollationElementIterator()
Destructor.
"Smart pointer" base class; do not use directly: use LocalPointer etc.
The RuleBasedCollator class provides the implementation of Collator, using data-driven tables.
UObject is the common ICU "boilerplate" class.
UnicodeString is a string class that stores Unicode characters directly and provides similar function...
struct UHashtable UHashtable
struct UCollationElements UCollationElements
The UCollationElements struct.
int8_t UBool
The ICU boolean type, a signed-byte integer.
#define U_FINAL
Defined to the C++11 "final" keyword if available.
C++ API: Common ICU base class UObject.
void * UClassID
UClassID is used to identify classes without using the compiler's RTTI.
Basic definitions for ICU, for both C and C++ APIs.
UErrorCode
Standard ICU4C error code type, a substitute for exceptions.
#define U_I18N_API
Set to export library symbols from inside the i18n library, and to import them from outside.
