Boost.Regexerror_type |
|
Type error type represents the different types of errors that can be raised by the library when parsing a regular expression.
namespace boost{ namespace regex_constants{ typedef implementation-specific-type error_type; static const error_type error_collate; static const error_type error_ctype; static const error_type error_escape; static const error_type error_backref; static const error_type error_brack; static const error_type error_paren; static const error_type error_brace; static const error_type error_badbrace; static const error_type error_range; static const error_type error_space; static const error_type error_badrepeat; static const error_type error_complexity; static const error_type error_stack; static const error_type error_bad_pattern; } // namespace regex_constants } // namespace boost
The type error_type is an implementation-specific enumeration type that may take one of the following values:
Constant | Meaning |
error_collate | An invalid collating element was specified in a [[.name.]] block. |
error_ctype | An invalid character class name was specified in a [[:name:]] block. |
error_escape | An invalid or trailing escape was encountered. |
error_backref | A back-reference to a non-existant marked sub-expression was encountered. |
error_brack | An invalid character set [...] was encountered. |
error_paren |
Mismatched '(' and ')'. |
error_brace | Mismatched '{' and '}'. |
error_badbrace | Invalid contents of a {...} block. |
error_range | A character range was invalid, for example [d-a]. |
error_space | Out of memory. |
error_badrepeat | An attempt to repeat something that can not be repeated - for example a*+ |
error_complexity | The expression became too complex to handle. |
error_stack | Out of program stack space. |
error_bad_pattern | Other unspecified errors. |
