Constructor & Destructor Documentation

UnaryMinusExpression()

template<typename Scalar , ExpressionType T>

constexpr slp::detail::UnaryMinusExpression< Scalar, T >::UnaryMinusExpression ( ExpressionPtr< Scalar >  lhs )

inlineexplicitconstexpr

Constructs an unary expression (an operator with one argument).

Parameters

lhs	Unary operator's operand.

Member Function Documentation

grad_expr_l()

template<typename Scalar , ExpressionType T>

ExpressionPtr< Scalar > slp::detail::UnaryMinusExpression< Scalar, T >::grad_expr_l ( const ExpressionPtr< Scalar > &  lhs, const ExpressionPtr< Scalar > &  rhs  ) const

inlineoverridevirtual

Returns ∂/∂l as an Expression.

Parameters

lhs	Left argument to binary operator.
rhs	Right argument to binary operator.

Returns

∂/∂l as an Expression.

Reimplemented from slp::detail::Expression< Scalar >.

grad_l()

template<typename Scalar , ExpressionType T>

Scalar slp::detail::UnaryMinusExpression< Scalar, T >::grad_l ( Scalar  lhs, Scalar  rhs  ) const

inlineoverridevirtual

Returns ∂/∂l as a Scalar.

Parameters

lhs	Left argument to binary operator.
rhs	Right argument to binary operator.

Returns

∂/∂l as a Scalar.

Reimplemented from slp::detail::Expression< Scalar >.

name()

template<typename Scalar , ExpressionType T>

std::string_view slp::detail::UnaryMinusExpression< Scalar, T >::name ( ) const

inlineoverridevirtual

Returns the name of this expression.

Returns

The name of this expression.

Implements slp::detail::Expression< Scalar >.

type()

template<typename Scalar , ExpressionType T>

ExpressionType slp::detail::UnaryMinusExpression< Scalar, T >::type ( ) const

inlineoverridevirtual

Returns the type of this expression (constant, linear, quadratic, or nonlinear).

Returns

The type of this expression.

Implements slp::detail::Expression< Scalar >.

value()

template<typename Scalar , ExpressionType T>

Scalar slp::detail::UnaryMinusExpression< Scalar, T >::value ( Scalar  lhs, Scalar  rhs  ) const

inlineoverridevirtual

Either nullary operator with no arguments, unary operator with one argument, or binary operator with two arguments. This operator is used to update the node's value.

Parameters

lhs	Left argument to binary operator.
rhs	Right argument to binary operator.

Returns

The node's value.

Implements slp::detail::Expression< Scalar >.
