Detailed Description

std::regex_error-compatible exception; every regex error this layer reports has this type.

• A syntax error: std's own code() and what().
• A strict-policy rejection (policy) of a pattern std accepts but REAL cannot run linearly: error_complexity, with a message naming REAL.
• An error the std backend raises while matching (error_complexity, error_stack): std's code.

Constructor & Destructor Documentation

regex_error() [1/3]

real::compat::regex_error::regex_error ( const std::regex_error &  error )

inlineexplicit

From a std error, keeping its code and message.

Parameters

[in]

error

The standard library error to adopt.

regex_error() [2/3]

real::compat::regex_error::regex_error ( std::regex_constants::error_type  code )

inlineexplicit

With a code alone, as std::regex_error(code); the message is std's for that code.

Parameters

[in]

code

The error category.

regex_error() [3/3]

real::compat::regex_error::regex_error ( std::regex_constants::error_type  code, std::string  message  )

inline

With an explicit code and message — the strict-policy rejection of a pattern REAL cannot represent linearly (error_complexity), carrying a REAL-identifiable message.

Parameters

[in]	code	The std::regex_constants::error_type to report.
[in]	message	The text what returns.

Member Function Documentation

what()

const char * real::compat::regex_error::what ( ) const

inlineoverridenoexcept

The message, which for a strict-policy rejection identifies REAL as the source.

Returns

A NUL-terminated message valid for this object's lifetime.
