public static class CallInvokerExtensions
Extends the CallInvoker class to provide the interceptor facility on the client side.
Namespace
Grpc.Core.InterceptorsAssembly
Grpc.Core.Api.dll
Methods
Intercept(CallInvoker, Interceptor)
public static CallInvoker Intercept(this CallInvoker invoker, Interceptor interceptor)
Returns a CallInvoker instance that intercepts the invoker with the given interceptor.
Parameters | |
---|---|
Name | Description |
invoker |
CallInvoker The underlying invoker to intercept. |
interceptor |
Interceptor The interceptor to intercept calls to the invoker with. |
Returns | |
---|---|
Type | Description |
CallInvoker |
Multiple interceptors can be added on top of each other by calling "invoker.Intercept(a, b, c)". The order of invocation will be "a", "b", and then "c". Interceptors can be later added to an existing intercepted CallInvoker, effectively building a chain like "invoker.Intercept(c).Intercept(b).Intercept(a)". Note that in this case, the last interceptor added will be the first to take control.
Intercept(CallInvoker, params Interceptor[])
public static CallInvoker Intercept(this CallInvoker invoker, params Interceptor[] interceptors)
Returns a CallInvoker instance that intercepts the invoker with the given interceptors.
Parameters | |
---|---|
Name | Description |
invoker |
CallInvoker The channel to intercept. |
interceptors |
Interceptor An array of interceptors to intercept the calls to the invoker with. Control is passed to the interceptors in the order specified. |
Returns | |

Intercept(CallInvoker, Func<Metadata, Metadata>)
public static CallInvoker Intercept(this CallInvoker invoker, Func<Metadata, Metadata> interceptor)
Returns a CallInvoker instance that intercepts the invoker with the given interceptor.
Parameters | |
---|---|
Name | Description |
invoker |
CallInvoker The underlying invoker to intercept. |
interceptor |
FuncMetadataMetadata An interceptor delegate that takes the request metadata to be sent with an outgoing call and returns a Metadata instance that will replace the existing invocation metadata. |
Returns | |
