virtual UBool reserveAppendCapacity(int32_t appendCapacity)
Tells the object that the caller is going to append roughly appendCapacity char16_ts.
virtual UBool appendCodeUnit(char16_t c)=0
Appends a 16-bit code unit.
virtual UBool appendString(const char16_t *s, int32_t length)
Appends a string.
virtual UBool appendCodePoint(UChar32 c)
Appends a code point.
virtual char16_t * getAppendBuffer(int32_t minCapacity, int32_t desiredCapacityHint, char16_t *scratch, int32_t scratchCapacity, int32_t *resultCapacity)
Returns a writable buffer for appending and writes the buffer's capacity to *resultCapacity.
UObject is the common ICU "boilerplate" class.
An Appendable implementation which writes to a UnicodeString.
virtual UBool reserveAppendCapacity(int32_t appendCapacity) override
Tells the UnicodeString that the caller is going to append roughly appendCapacity char16_ts.
virtual UBool appendCodePoint(UChar32 c) override
Appends a code point to the string.
UnicodeStringAppendable(UnicodeString &s)
Aliases the UnicodeString (keeps its reference) for writing.
virtual char16_t * getAppendBuffer(int32_t minCapacity, int32_t desiredCapacityHint, char16_t *scratch, int32_t scratchCapacity, int32_t *resultCapacity) override
Returns a writable buffer for appending and writes the buffer's capacity to *resultCapacity.
virtual UBool appendString(const char16_t *s, int32_t length) override
Appends a string to the UnicodeString.
virtual UBool appendCodeUnit(char16_t c) override
Appends a 16-bit code unit to the string.
~UnicodeStringAppendable()
Destructor.
UnicodeString is a string class that stores Unicode characters directly and provides similar function...
int32_t UChar32
Define UChar32 as a type for single Unicode code points.
int8_t UBool
The ICU boolean type, a signed-byte integer.
C++ API: Common ICU base class UObject.
Basic definitions for ICU, for both C and C++ APIs.
#define U_COMMON_API
Set to export library symbols from inside the common library, and to import them from outside.
