#include <parseerr.h>
Data Fields | |
int32_t | line |
The line on which the error occured. | |
int32_t | offset |
The character offset to the error. | |
UChar | preContext [U_PARSE_CONTEXT_LEN] |
Textual context before the error. | |
UChar | postContext [U_PARSE_CONTEXT_LEN] |
Textual context after the error. |
It is used by ICU parsing engines that parse long rules, patterns, or programs, where the text being parsed is long enough that more information than a UErrorCode is needed to localize the error.
The code field is an integer error code specific to each parsing engine, but globally unique. See the engine header file for possible values. The line, offset, and context fields are optional; parsing engines may choose not to use to use them.
Examples of engines which use UParseError (or may use it in the future) are RuleBasedTransliterator and RuleBasedBreakIterator.

The line on which the error occured. If the parse engine is not using this field, it should set it to zero. Otherwise it should be a positive integer. The default value of this field is -1. It will be set to 0 if the code populating this struct is not using line numbers. |
|
The character offset to the error. If the line field is being used, then this offset is from the start of the line. If the line field is not being used, then this offset is from the start of the text.The default value of this field is -1. It will be set to appropriate value by the code that populating the struct. |
|
Textual context after the error. Null-terminated. May be the empty string if not implemented by parser. |
|
Textual context before the error. Null-terminated. May be the empty string if not implemented by parser. |
