char32At)(const UReplaceable *rep, int32_t offset)
|
UChar32(*
Function pointer that returns a UChar32 code point at the given offset into this text.
|
charAt)(const UReplaceable *rep, int32_t offset)
|
UChar(*
Function pointer that returns a UChar code units at the given offset into this text; 0 <= offset < n, where n is the value returned by (*length)(rep).

char32At
UChar32(* UReplaceableCallbacks::char32At)(const UReplaceable *rep, int32_t offset)
Function pointer that returns a UChar32 code point at the given offset into this text.
See unistr.h for a description of charAt() vs. char32At().

Parameters |
|
||||
Returns |
The UChar32 (code point) at offset, or U+FFFF if the offset is out of bounds.
|
charAt
UChar(* UReplaceableCallbacks::charAt)(const UReplaceable *rep, int32_t offset)
Function pointer that returns a UChar code units at the given offset into this text; 0 <= offset < n, where n is the value returned by (*length)(rep).
See unistr.h for a description of charAt() vs. char32At().

Parameters |
|
||||
Returns |
The UChar (code unit) at offset, or U+FFFF if the offset is out of bounds.
|
copy
void(* UReplaceableCallbacks::copy)(UReplaceable *rep, int32_t start, int32_t limit, int32_t dest)
Function pointer that copies text between start and limit in this text to another index in the text.
Attributes (out of band info) should be retained. After this call, there will be (at least) two copies of the characters originally located at start..limit-1.
