Constructors

ConstantExpression(Double)

Initializes a new instance of the ConstantExpression class.

Declaration

public ConstantExpression(double value)

Parameters

Type	Name	Description
System.Double	value	The value.

Properties

Constant

Gets the constant.

Declaration

public override double Constant { get; }

Property Value

Type	Description
System.Double

Overrides

Expression.Constant

ConstantValue

Gets the constant.

Declaration

public double ConstantValue { get; }

Property Value

Type	Description
System.Double

ContainsAtMostOneVariable

Declaration

public override bool ContainsAtMostOneVariable { get; }

Property Value

Type	Description
System.Boolean

Overrides

Expression.ContainsAtMostOneVariable

ContainsNoVariables

Declaration

public override bool ContainsNoVariables { get; }

Property Value

Type	Description
System.Boolean

Overrides

Expression.ContainsNoVariables

IsLinear

Gets or sets a value indicating whether this instance is linear.

Declaration

public override bool IsLinear { get; }

Property Value

Type	Description
System.Boolean	Always true because a ConstantExpression is always linear.

Overrides

Expression.IsLinear

Terms

Gets the terms.

Declaration

public override IEnumerable<Term> Terms { get; }

Property Value

Type	Description
System.Collections.Generic.IEnumerable<Term>	Always null because a ConstantExpression has no Terms.

Overrides

Expression.Terms

Variables

Gets the variables.

Declaration

public override IEnumerable<Variable> Variables { get; }

Property Value

Type	Description
System.Collections.Generic.IEnumerable<Variable>	Always null because a ConstantExpression has no Variables.

Overrides

Expression.Variables

Methods

ToString()

Returns a System.String that represents this instance.

Declaration

public override string ToString()

Returns

Type	Description
System.String	A System.String that represents this instance.

Overrides

System.Object.ToString()
