Detailed Description

Position structure for utrans_transIncremental() incremental transliteration.

This structure defines two substrings of the text being transliterated. The first region, [contextStart, contextLimit), defines what characters the transliterator will read as context. The second region, [start, limit), defines what characters will actually be transliterated. The second region should be a subset of the first.

After a transliteration operation, some of the indices in this structure will be modified. See the field descriptions for details.

contextStart <= start <= limit <= contextLimit

Note: All index values in this structure must be at code point boundaries. That is, none of them may occur between two code units of a surrogate pair. If any index does split a surrogate pair, results are unspecified.

Field Documentation

◆ contextLimit

int32_t UTransPosition::contextLimit

Ending index, exclusive, of the context to be considered for a transliteration operation.

The transliterator will ignore anything at or after this index. INPUT/OUTPUT parameter: This parameter is updated to reflect changes in the length of the text, but points to the same logical position in the text.

◆ contextStart

int32_t UTransPosition::contextStart

Beginning index, inclusive, of the context to be considered for a transliteration operation.

The transliterator will ignore anything before this index. INPUT/OUTPUT parameter: This parameter is updated by a transliteration operation to reflect the maximum amount of antecontext needed by a transliterator.

◆ limit

int32_t UTransPosition::limit

Ending index, exclusive, of the text to be transliterated.

INPUT/OUTPUT parameter: This parameter is updated to reflect changes in the length of the text, but points to the same logical position in the text.

◆ start

int32_t UTransPosition::start

Beginning index, inclusive, of the text to be transliterated.

INPUT/OUTPUT parameter: This parameter is advanced past characters that have already been transliterated by a transliteration operation.
