Method IntroduceUnaryOperator

IntroduceUnaryOperator(INamedType, string, IType, IType, OperatorKind, OverrideStrategy, Action<IMethodBuilder>?, object?, object?)

Introduces a new unary operator or overrides the implementation of the existing one.

Declaration
IIntroductionAdviceResult<IMethod> IntroduceUnaryOperator(INamedType targetType, string template, IType inputType, IType resultType, OperatorKind kind, OverrideStrategy whenExists = OverrideStrategy.Default, Action<IMethodBuilder>? buildOperator = null, object? args = null, object? tags = null)
Parameters
Type Name Description
INamedType targetType

The type into which the unary operator must be introduced.

string template

Name of the method of the aspect class that will be used as a template for the introduced operator. This method must be annotated with TemplateAttribute.

IType inputType

The type of the operator's input parameter.

IType resultType

The return type of the operator.

OperatorKind kind

The kind of unary operator to introduce (e.g., UnaryPlus, UnaryNegation).

OverrideStrategy whenExists

Determines the implementation strategy when a unary operator of the same signature is already declared in the target type. The default strategy is to fail with a compile-time error.

Action<IMethodBuilder> buildOperator

An optional callback that allows you to configure the introduced operator method, such as adding custom attributes.

object args

An object (typically of anonymous type) whose properties map to parameters or type parameters of the template method.

object tags

An optional opaque object of anonymous type passed to the template method and exposed under the Tags property of the meta API.

Returns
Type Description
IIntroductionAdviceResult<IMethod>

An IIntroductionAdviceResult<T> representing the result of the advice. The Declaration property provides access to the introduced unary operator.
