Introduction

IQuery is the parameter in handler.Handle() method. Its main properties are .Request and .Response. Query is instantiated by service implementation.

// Create service
IService service = Services.Create(ServiceHandlers.Instance);
// Create request
string request = "Request";
// Create response
IEntry<string> entry = new Entry<string>();
// Create query
IQuery<string, string> query = new Query<string, string>(
    service: service,
    context: new Dictionary<string, object>(),
    cancelToken: default,
    request: request,
    response: entry);

// Assign response
query.Response.SetValue( query.Request + "-Suffix" );

Query interfaces:

├── IQuery<Request, Response>
