Member Function Documentation

default_error_condition()

error_condition bsl::error_category::default_error_condition ( int  value ) const

inlinevirtual

Return an error_condition object initialized with the specified value and this object as the error category.

equivalent() [1/2]

bool bsl::error_category::equivalent ( const error_code &  code, int  condition  ) const

inlinevirtual

equivalent() [2/2]

bool bsl::error_category::equivalent ( int  code, const error_condition &  condition  ) const

inlinevirtual

Return, for the error category defined by this object, whether the specified code and condition are considered equivalent.

message()

std::string bsl::error_category::message ( int  value ) const

inlinepure virtual

Return a string describing the error condition denoted by the specified value.

name()

const char * bsl::error_category::name ( ) const

inlinepure virtual

Return the name of this error category.

operator!=()

bool bsl::error_category::operator!= ( const error_category &  other ) const

inline

Return whether this object is different than the specified other.

operator<()

bool bsl::error_category::operator< ( const error_category &  other ) const

inline

Return whether this object precedes the specified other in a total ordering of error_category objects.

operator==()

bool bsl::error_category::operator== ( const error_category &  other ) const

inline

Return whether this object is the same as the specified other.
