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

◆ 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
repA pointer to "this" UReplaceable object.
offsetThe index at which to fetch the UChar32 (code point).
Returns
The UChar32 (code point) at offset, or U+FFFF if the offset is out of bounds.
Stable:
ICU 2.0

Definition at line 89 of file urep.h.

◆ 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
repA pointer to "this" UReplaceable object.
offsetThe index at which to fetch the UChar (code unit).
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.

Parameters
repA pointer to "this" UReplaceable object.
startthe starting index of the text to be copied, inclusive.
limitthe ending index of the text to be copied, exclusive.
destthe index at which the copy of the UChars should be inserted.

Definition at line 148 of file urep.h.

◆ extract

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
repA pointer to "this" UReplaceable object.
startoffset of first character which will be copied into the array
limitoffset immediately following the last character to be copied
dstarray in which to copy characters. The length of dst must be at least (limit - start).
Stable:
ICU 2.1

Definition at line 127 of file urep.h.

◆ length

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

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

Parameters
repA pointer to "this" UReplaceable object.
Returns
The length of the text.
Stable:
ICU 2.0

Definition at line 63 of file urep.h.

◆ replace

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
repA pointer to "this" UReplaceable object.
startthe starting index of the text to be replaced, inclusive.
limitthe ending index of the text to be replaced, exclusive.
textthe new text to replace the UChars from start..limit-1.
textLengththe number of UChars at text, or -1 if text is null-terminated.
