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.
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.
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.
