Engineering Structure of table ATL File Name Description Projectname. cpp It is the main project file. It contains the support functions required by COM, which are used to provide host files for your components. Projectname. h The interface declaration of the component in the host file. The midl compiler automatically generates the file.The IDL file of the compilation project is used to generate the file.

compare whether thrift, protobuf, and Avro serialize data to binary and support schema evoluation. The example I will use is a little object describing a person. In json I wocould write it like this: { "userName": "Martin", "favouriteNumber": 1337, "interests": ["daydreaming", "hacking"]} This JSON encoding can be our baseline. If I remove all the whitespace it consumes82Bytes. Protocol Buffers The Protocol buffers schema for the person object might look something like this: message Pe

Access the custom structure array When accessing the custom structure array, you can use the Type Definitions automatically generated by # iimport or compiled by IDL. If there is no way to get the declaration of the custom structure, you can use the method in the irecordinfo interface to indirectly access the custom structure. First, you need to get the length of the custom structure, wh

implementation method of classes in C ++, we need to pass a class pointer, which is actually a structure pointer, the problem in the Forum is that errors such as "undefined type" are always said during midl compilation. The following describes the role of midl.Midl is only a compiler provided by Microsoft to compile the code written by IDL (Interface Definition Language) or odl (Object Definition Language. This compiler compiles.

This itinerary is then created and notified by the Publish/subscribe interaction mode, including the dispatch service for locating available drivers.Now that we understand the interaction pattern, let's look at how to define the API.Defining the APIAn API is a contract between a server and a client. Regardless of the IPC mechanism chosen, it is important to use an interactive definition language (IDL) to precisely define t

But JSON itself lacks a standard schema that is widely accepted as XML, and the general HTTP + JSON remote invocation method lacks the standard IDL (interface Definition language) like thrift,corba,webservices and so on. Causes the service side and the client not to form the strong service contract, also cannot do for example automatic code ge
