Constructor & Destructor Documentation

◆ CallbackContext()

operations_research::math_opt::Gurobi::CallbackContext::CallbackContext	(	Gurobi *	gurobi,
		void *	cb_data,
		int	where )

For internal use only.

Member Function Documentation

◆ CbCut()

absl::Status operations_research::math_opt::Gurobi::CallbackContext::CbCut	(	absl::Span< const int >	cutind,
		absl::Span< const double >	cutval,
		char	cutsense,
		double	cutrhs ) const

Calls GRBcbcut().

Definition at line 817 of file g_gurobi.cc.

◆ CbGetDouble()

absl::StatusOr< double > operations_research::math_opt::Gurobi::CallbackContext::CbGetDouble ( int what ) const

Calls GRBcbget() on "what" with result type double, see Callback Codes in Gurobi docs for values of "what".

Definition at line 793 of file g_gurobi.cc.

◆ CbGetDoubleArray()

absl::Status operations_research::math_opt::Gurobi::CallbackContext::CbGetDoubleArray	(	int	what,
		absl::Span< double >	result ) const

Calls GRBcbget() on "what" with result type double*, see Callback Codes in Gurobi docs for values of "what".

The user is responsible for ensuring that result is large enough to hold the result.

Definition at line 801 of file g_gurobi.cc.

◆ CbGetInt()

absl::StatusOr< int > operations_research::math_opt::Gurobi::CallbackContext::CbGetInt ( int what ) const

Calls GRBcbget() on "what" with result type int, see Callback Codes in Gurobi docs for values of "what".

Definition at line 786 of file g_gurobi.cc.

◆ CbGetMessage()

absl::StatusOr< std::string > operations_research::math_opt::Gurobi::CallbackContext::CbGetMessage ( ) const

Calls GRBcbget() where what=MSG_STRING (call only at where=MESSAGE).

Definition at line 807 of file g_gurobi.cc.

◆ CbLazy()

absl::Status operations_research::math_opt::Gurobi::CallbackContext::CbLazy	(	absl::Span< const int >	lazyind,
		absl::Span< const double >	lazyval,
		char	lazysense,
		double	lazyrhs ) const

Calls GRBcblazy().

Definition at line 827 of file g_gurobi.cc.

◆ CbSolution()

absl::StatusOr< double > operations_research::math_opt::Gurobi::CallbackContext::CbSolution ( absl::Span< const double > solution ) const

Calls GRBcbsolution().
