Member Enumeration Documentation

ErrorCode

enum operations_research::glop::Status::ErrorCode

Possible kinds of errors.

Enumerator
GLOP_OK	Not an error. Returned on success.
ERROR_LU	The LU factorization of the current basis couldn't be computed.
ERROR_BOUND	The current variable values are out of their bound modulo the tolerance.
ERROR_NULL	A pointer argument was NULL when it shouldn't be.
ERROR_INVALID_PROBLEM	The linear program is invalid or it does not have the required format.

Constructor & Destructor Documentation

Status() [1/2]

operations_research::glop::Status::Status

(

)

Creates a "successful" status.

Definition at line 24 of file status.cc.

Status() [2/2]

operations_research::glop::Status::Status	(	ErrorCode	error_code,
		std::string	error_message )

Creates a status with the specified error code and error message. If "code == 0", error_message is ignored and a Status object identical to Status::OK is constructed.
