Member Function Documentation

build() [1/2]

auto xpress::VariableBuilder::ArrayBuilder::build ( xpress::objects::XpressProblem * prob ) -> std::vector< xpress::objects::Variable>
inline

Create variables as specified by this builder.

Parameters
prob The problem in which to create the variables.
Returns
The generated variables.
Since
44.00

build() [2/2]

auto xpress::VariableBuilder::ArrayBuilder::build ( XPRSProblem * prob ) -> std::vector< int>
inline

Create columns as specified by this builder.

Parameters
prob The problem in which to create the columns.
Returns
Indices of the generated columns.
Since
44.00

withLB() [1/2]

auto xpress::VariableBuilder::ArrayBuilder::withLB ( double newLb ) -> ArrayBuilder&
inline

Set a constant lower bound for all columns or variables.

Parameters
newLb The lower bound for all columns or variables created by this builder.
Returns
Always returns this instance.
Since
44.00

withLB() [2/2]

template<typename Func0 , typename Func0Invocable = typename std::enable_if<std::is_convertible<typename std::invoke_result<Func0,int>::type,double>::value>::type>
auto xpress::VariableBuilder::ArrayBuilder::withLB ( Func0 newLb ) -> ArrayBuilder&
inline

Set a lower bound that depends on the index.

Parameters
newLb The lower bound for all columns or variables created by this builder.
Template Parameters
Func0 auto (int) -> double: Maps (int) to double.
Returns
Always returns this instance.
Since
44.00

withLimit() [1/2]

auto xpress::VariableBuilder::ArrayBuilder::withLimit ( double newLimit ) -> ArrayBuilder&
inline

Set a constant limit for all columns or variables.

A limit specifies the bounds for semi-continuous/integer columns or variables and the limit for partial integer columns or variables. It does not apply to columns or variables of other types.

Parameters
newLimit The limit for all columns or variables created by this builder.
Returns
Always returns this instance.
Since
44.00

withLimit() [2/2]

template<typename Func0 , typename Func0Invocable = typename std::enable_if<std::is_convertible<typename std::invoke_result<Func0,int>::type,double>::value>::type>
auto xpress::VariableBuilder::ArrayBuilder::withLimit ( Func0 newLimit ) -> ArrayBuilder&
inline

Set a limit that depends on the index.

A limit specifies the bounds for semi-continuous/integer columns or variables and the limit for partial integer columns or variables. It does not apply to columns or variables of other types.

Parameters
newLimit The limit for all columns or variables created by this builder.
Template Parameters
Func0 auto (int) -> double: Maps (int) to double.
Returns
Always returns this instance.
Since
44.00

withName() [1/2]

template<typename Func0 , typename Func0Invocable = typename std::enable_if<std::is_convertible<typename std::invoke_result<Func0,int>::type,std::optional<std::string>>::value>::type>
auto xpress::VariableBuilder::ArrayBuilder::withName ( Func0 newName ) -> ArrayBuilder&
inline

Set a name that depends on the index.

Parameters
newName The name for all columns or variables created by this builder.
Template Parameters
Func0 auto (int) -> std::optional<std::string>: Maps (int) to std::optional<std::string>.
Returns
Always returns this instance.
Since
44.00

withName() [2/2]

auto xpress::VariableBuilder::ArrayBuilder::withName ( std::optional< std::string > newName ) -> ArrayBuilder&
inline

Set a constant name for all columns or variables.

Parameters
newName The name for all columns or variables created by this builder. This must be std::nullopt or a format string that will be invoked with the index as argument.
Returns
Always returns this instance.
Since
44.00

withType() [1/2]

auto xpress::VariableBuilder::ArrayBuilder::withType ( ColumnType newType ) -> ArrayBuilder&
inline

Set the type for all columns or variables.

Parameters
newType The type for all columns or variables created by this builder.
Returns
Always returns this instance.
Since
44.00

withType() [2/2]

template<typename Func0 , typename Func0Invocable = typename std::enable_if<std::is_convertible<typename std::invoke_result<Func0,int>::type,ColumnType>::value>::type>
auto xpress::VariableBuilder::ArrayBuilder::withType ( Func0 newType ) -> ArrayBuilder&
