Constructor & Destructor Documentation

◆ ConstExpression() [1/2]

constexpr sleipnir::detail::ConstExpression::ConstExpression ( )

constexprdefault

Constructs a constant expression with a value of zero.

◆ ConstExpression() [2/2]

constexpr sleipnir::detail::ConstExpression::ConstExpression ( double value )

inlineexplicitconstexpr

Constructs a nullary expression (an operator with no arguments).

Parameters

value The expression value.

Member Function Documentation

◆ Type()

ExpressionType sleipnir::detail::ConstExpression::Type ( ) const

inlineoverridevirtual

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

Implements sleipnir::detail::Expression.

◆ Value()

double sleipnir::detail::ConstExpression::Value	(	double	lhs,
		double	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.
