structure changes, you must re-edit the IDL file, code generation, and then compile the loaded process, compared with other IDL tools can be regarded as the weakness of Thrift, Thrift is suitable for large-scale data exchange and storage of common tools, for large systems of internal data transmission in relation to JSON and XML in terms of performance, transmission size has obvious advantages.Thrift is a

interfaces. They need to point to different routines and return different results.Therefore, their respective QueryInterface routines (queryinterfacecf and queryinterfacemc) are directed by different virtual function tables.Similarly, addref and release must be customized by different interfaces that support them. Type Library:Every COM interface obtains information from the system registry. The definitions of these interfaces are described by an Interface Definition Language (

Jacorb generally consists of the following five steps: 1. Write the definition of the IDL InterfaceThe interface is defined in SSS. IDL Using IDL (Interface Definition Language ). 2. Compile the IDL Interface Definition to generate a Java classRun the following command to compile the interface file:$

the implementation of the specific language to deal with, which may be one of the reasons why he is not widely popular. In fact, CORBA has a very well-known successor, and he is the thrift framework of the Facebook company. Thrift is also using an IDL compiler to generate multiple languages of the remote invocation scheme, and with C++/java and other languages complete implementation of the communication bearer, so in the open source framework is a p

What Thrift is.Thrift from the famous Facebook hand, in 2007 Facebook submitted the Apache Foundation to thrift as an open source project, For Facebook at the time, the creation of thrift was designed to address the large amount of data transmitted between the systems in the Facebook system, as well as the cross-platform nature of the different locales of the system. So thrift can support a variety of programming languages, such as C + +, C #, Cocoa, Erlang, Haskell, Java, Ocami, Perl, PHP, Pyth

A COM component in Windows is an important part of Windows, can be registered as a public component of the system, or may not be registered for direct invocation. Before calling COM components in the D language, we need to understand COM components. COM components have a common interface, written in the IDL language, using the Mild.exe compiler to generate a TLB format file, usually called a type library, when generating a COM component DLL, the file
