Member Enumeration Documentation

Type

enum class kanzi::TextBreakIterator::Type

strong

Type of text break iterator.

Enumerator
Word	Iterate word boundaries.
Line	Iterate line breaks.

Constructor & Destructor Documentation

TextBreakIterator() [1/3]

kanzi::TextBreakIterator::TextBreakIterator ( Type type, const char * utf8String, int64_t utf8Length )

explicit

Constructs a text break iterator for a UTF-8 string.

Indexes returned by TextBreakIterator refer to the elements in the original character array.

Parameters

type	Type of the text break iterator.
utf8String	String in UTF-8 format.
utf8Length	A length of the given string. If the string is 0-terminated, -1.

TextBreakIterator() [2/3]

kanzi::TextBreakIterator::TextBreakIterator ( Type type, const char16_t * utf16String, int64_t utf16Length )

explicit

Constructs a text break iterator for a UTF-16 string.

Indexes returned by TextBreakIterator refer to the elements in the original character array.

Parameters

type	Type of the text break iterator.
utf16String	String in UTF-16 format.
utf16Length	A length of the given string. If the string is 0-terminated, -1.

TextBreakIterator() [3/3]

kanzi::TextBreakIterator::TextBreakIterator ( TextBreakIterator && )

noexcept

Move constructor.

~TextBreakIterator()

kanzi::TextBreakIterator::~TextBreakIterator

(

)

TextBreakIterator destructor.

Member Function Documentation

operator=()

TextBreakIterator & kanzi::TextBreakIterator::operator= ( TextBreakIterator && )

noexcept

Move assignment.

first()

size_t kanzi::TextBreakIterator::first

(

)

Sets the iterator position to the beginning of the string.

Returns

New iterator position (zero).

last()

size_t kanzi::TextBreakIterator::last

(

)

Sets the iterator position to after the last character of the string.

Returns

New iterator position.

next()

size_t kanzi::TextBreakIterator::next

(

)

Advance the iterator to the next boundary.

Returns

New iterator position. If all boundaries have already been returned, returns s_done.

previous()

size_t kanzi::TextBreakIterator::previous

(

)

Advance the iterator to the previous boundary.

Returns

New iterator position. If all boundaries have already been returned, returns s_done.

current()

size_t kanzi::TextBreakIterator::current

(

)

const

Returns the current position of the iterator.

Returns

Current position of the iterator.

preceding()

size_t kanzi::TextBreakIterator::preceding

(

size_t

offset

)

Sets the iterator to the first boundary that precedes the given offset.

Parameters

offset

A character offset in the original character array.

Returns

New iterator position. If all boundaries have already been returned, returns s_done.

following()

size_t kanzi::TextBreakIterator::following

(

size_t

offset

)

Sets the iterator to the first boundary that follows the given offset.

Parameters

offset

A character offset in the original character array.

Returns

New iterator position. If all boundaries have already been returned, returns s_done.

char32At()

char32_t kanzi::TextBreakIterator::char32At

(

size_t

offset

)

const

Returns the UTF-32 Unicode codepoint at the given offset.

Parameters

offset

A character offset in the original character array.

Returns

UTF-32 Unicode codepoint at the given offset.
