UReplaceableCallbacks
A set of function pointers that transliterators use to manipulate a UReplaceable.
Definition urep.h:51
UReplaceableCallbacks::extract
void(* extract)(UReplaceable *rep, int32_t start, int32_t limit, UChar *dst)
Function pointer that copies the characters in the range [start, limit) into the array dst.
Definition urep.h:125
UReplaceableCallbacks::length
int32_t(* length)(const UReplaceable *rep)
Function pointer that returns the number of UChar code units in this text.
Definition urep.h:61
UReplaceableCallbacks::replace
void(* replace)(UReplaceable *rep, int32_t start, int32_t limit, const UChar *text, int32_t textLength)
Function pointer that replaces text between start and limit in this text with the given text.
Definition urep.h:106
UReplaceableCallbacks::copy
void(* 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.
Definition urep.h:146
UReplaceableCallbacks::char32At
UChar32(* char32At)(const UReplaceable *rep, int32_t offset)
Function pointer that returns a UChar32 code point at the given offset into this text.
Definition urep.h:87
UReplaceableCallbacks::charAt
UChar(* 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,...
Definition urep.h:74
UChar32
int32_t UChar32
Define UChar32 as a type for single Unicode code points.
Definition umachine.h:332
U_CDECL_END
#define U_CDECL_END
This is used to end a declaration of a library private ICU C API.
Definition umachine.h:83
U_CDECL_BEGIN
#define U_CDECL_BEGIN
This is used to begin a declaration of a library private ICU C API.
Definition umachine.h:82
UChar
uint16_t UChar
Define UChar to be UCHAR_TYPE, if that is #defined (for example, to char16_t), or wchar_t if that is ...
Definition umachine.h:312
UReplaceable
void * UReplaceable
An opaque replaceable text object.
Definition urep.h:42
