linebreak_break()

gcstring_t ** linebreak_break	(	linebreak_t *	lbobj,
		unistr_t *	input )

Perform line breaking algorithm on complete input.

This function will consume constant size of heap.

Parameters

[in]	lbobj	linebreak object.
[in]	input	Unicode string.

Returns

array of broken grapheme cluster strings terminated by NULL. If internal error occurred, lbobj->errnum is set then NULL is returned.

linebreak_break_fast()

gcstring_t ** linebreak_break_fast	(	linebreak_t *	lbobj,
		unistr_t *	input )

Perform line breaking algorithm on complete input.

This function will consume heap size proportional to input size. linebreak_break() is highly recommended.

Parameters

[in]	lbobj	linebreak object.
[in]	input	Unicode string.

Returns

array of broken grapheme cluster strings terminated by NULL. If internal error occurred, lbobj->errnum is set then NULL is returned.

linebreak_break_from_utf8()

gcstring_t ** linebreak_break_from_utf8	(	linebreak_t *	lbobj,
		char *	input,
		size_t	len,
		int	check )

Perform line breaking algorithm on UTF-8 text

This function will consume constant size of heap.

Parameters

[in]	lbobj	linebreak object.
[in]	input	UTF-8 string, must not be NULL.
[in]	len	length of UTF-8 string.
[in]	check	check input. See sombok_decode_utf8().

Returns

array of broken grapheme cluster strings terminated by NULL. If internal error occurred, lbobj->errnum is set then NULL is returned.

linebreak_break_partial()

gcstring_t ** linebreak_break_partial ( linebreak_t * lbobj, unistr_t * input )

extern

Perform line breaking algorithm with incremental inputs.

Parameters

[in]	lbobj	linebreak object.
[in]	input	Unicode string; give NULL to specify end of input.

Returns

array of (partial) broken grapheme cluster strings terminated by NULL. If internal error occurred, lbobj->errnum is set then NULL is returned.

linebreak_free_result()

void linebreak_free_result	(	gcstring_t **	result,
		int	deep )

linebreak_lbrule()

propval_t linebreak_lbrule	(	propval_t	b_idx,
		propval_t	a_idx )

Deprecated

Use linebreak_get_lbrule().

Get breaking rule between two classes

From given two line breaking classes, get breaking rule determined by internal data.

Parameters

[in]	a_idx	line breaking class.
[in]	b_idx	line breaking class.

Returns

line breaking action: MANDATORY, DIRECT, INDIRECT or PROHIBITED. If action was not determined, returns DIRECT.

Note

This method gives just approximate description of line breaking behavior. Especially, it won't give meaningful value related to classes AI and CJ. See also linebreak_get_lbrule().
