Constructors

Not()

Initializes a new NOT function instance for logical negation.

public Not()

Fields

FunctionName

string

The name of the function.

public static readonly string FunctionName

Properties

ArgumentConversionRules

Gets the rules controlling how arguments are converted before evaluation.

public override ArgumentConversionRules ArgumentConversionRules { get; }

Property Value:

The argument conversion rules as ArgumentConversionRules.

Overrides: BooleansInFunction.ArgumentConversionRules

FunctionInfo

Gets metadata describing the function's category, description, and argument structure.

public override FunctionInfo FunctionInfo { get; }

Property Value:

The function info as FunctionInfo.

Overrides: FunctionBase.FunctionInfo

When true, FunctionBase automatically evaluates this function element-wise over any multi-element array argument and returns a spilled array result. Override to true in pure scalar functions (e.g. ABS, LEN, MOD) where applying the function independently to each element of an input array is the correct dynamic-array behavior. Leave false (the default) for reducers.

public override bool LiftsOverArrays { get; }

Overrides: FunctionBase.LiftsOverArrays

Name

string

Gets the function name "NOT" used in formulas.

public override string Name { get; }

Property Value:

The name as String.

Overrides: FunctionBase.Name

Methods

EvaluateOverride(FunctionEvaluationContext<bool>)

Evaluates the function by inverting the boolean argument and returning the opposite value.

protected override RadExpression EvaluateOverride(FunctionEvaluationContext<bool> context)

Parameters:contextFunctionEvaluationContext<bool>

The context.

Returns:

RadExpression

Functions result as RadExpression.

Overrides: FunctionWithSameTypeArguments<bool>.EvaluateOverride(FunctionEvaluationContext<bool>)
