_UReplaceableCallbacks Struct Reference

A set of function pointers that transliterators use to manipulate a UReplaceable. More...

#include <urep.h>


Data Fields

int32_t(* length )(const UReplaceable *rep)
 Function pointer that returns the number of UChar code units in this text.
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, where n is the value returned by (*length)(rep).
UChar32(* char32At )(const UReplaceable *rep, int32_t offset)
 Function pointer that returns a UChar32 code point at the given offset into this text.
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.
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.
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.


Detailed Description

A set of function pointers that transliterators use to manipulate a UReplaceable.

The caller should supply the required functions to manipulate their text appropriately. Related to the C++ class Replaceable.


Field Documentation

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().

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().

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.

Parameters:
start the starting index of the text to be copied, inclusive.
limit the ending index of the text to be copied, exclusive.
dest the index at which the copy of the UChars should be inserted.

void(* _UReplaceableCallbacks::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.

Parameters:
start offset of first character which will be copied into the array
limit offset immediately following the last character to be copied
dst array in which to copy characters. The length of dst must be at least (limit - start). ICU 2.1

int32_t(* _UReplaceableCallbacks::length)(const UReplaceable *rep)
 

Function pointer that returns the number of UChar code units in this text.

void(* _UReplaceableCallbacks::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.

Attributes (out of band info) should be retained.

Parameters:
start the starting index of the text to be replaced, inclusive.
limit the ending index of the text to be replaced, exclusive.
text the new text to replace the UChars from start..limit-1.
textLength the number of UChars at text, or -1 if text is null-terminated.
