Method InterceptMethods

InterceptMethods<TScope>(IAdviser<TScope>, Func<IMethodInterceptionBuilder, IMethodInterception>)

Registers the interception of the uses of methods, described by a delegate.

Declaration

public static void InterceptMethods<TScope>(this IAdviser<TScope> adviser, Func<IMethodInterceptionBuilder, IMethodInterception> build) where TScope : class, IDeclaration

Parameters

Type	Name	Description
IAdviser<TScope>	adviser	An adviser whose target is the scope declaration.
Func<IMethodInterceptionBuilder, IMethodInterception>	build	A delegate that receives an IMethodInterceptionBuilder, selects the intercepted methods, chooses how the calls are intercepted, and returns the resulting IMethodInterception, for instance `b => b.Type( typeof(Console) ).Methods( "WriteLine" ).RedirectToSynthesizedMethod( nameof(this.Log) )`. It is invoked once, before this method returns.

Type Parameters

Name	Description
TScope

Exceptions

Type	Condition
ArgumentNullException	`build` is `null`.
ArgumentException	The delegate returned `null`, or a value that does not describe a complete interception.
InvalidOperationException	The delegate discarded a value that it created, or the project that executes the registration does not reference the `Metalama.Extensions.Interceptors` package.

InterceptMethods(ITypeAmender, Func<IMethodInterceptionBuilder, IMethodInterception>)

Registers the interception of the uses of methods, described by a delegate. The scope declaration is the type of the fabric.

Declaration

Full screen

public static void InterceptMethods(this ITypeAmender amender, Func<IMethodInterceptionBuilder, IMethodInterception> build)

Parameters

Type	Name	Description
ITypeAmender	amender	The amender of a type fabric.
Func<IMethodInterceptionBuilder, IMethodInterception>	build	A delegate that describes the interception, as in InterceptMethods<TScope>(IAdviser<TScope>, Func<IMethodInterceptionBuilder, IMethodInterception>).

Remarks

This overload resolves the ambiguity between the IAdviser<T> and IQuery<TDeclaration> overloads for ITypeAmender, which implements both interfaces. The registration is made through the query.

Exceptions

Type	Condition
ArgumentNullException	`build` is `null`.
ArgumentException	The delegate returned `null`, or a value that does not describe a complete interception.
InvalidOperationException	The delegate discarded a value that it created, or the project that executes the registration does not reference the `Metalama.Extensions.Interceptors` package.
