Most of the time, the system can automatically generate all // of messaging mechanism from these definitions, but sometimes some manual // coding is required. In these cases, you will also have an XXX_messages.cc // implemation file as well. // // The senders of your messages will include your XXX_messages.h file to // get the full set of definitions they need to send your messages. // // Each XXX_messages.h file must be registered with the IPC system. This // requires adding two things: // - An XXXMsgStart value to the IPCMessageStart enum in ipc_message_utils.h // - An inclusion of XXX_messages.h file in a message generator .h file // // The XXXMsgStart value is an enumeration that ensures uniqueness for // each different message file. Later, you will use this inside your // XXX_messages.h file before invoking message declatation macros: // #define IPC_MESSAGE_START XXXMsgStart // ( ... your macro invocations go here ... ) // // Message Generator Files // // A message generator .h header file pulls in all other message-declaring // headers for a given component. It is included by a message generator // .cc file, which is where all the generated code will wind up. Typically, // you will use an existing generator (e.g. common_message_generator.cc and // common_message_generator.h in /chrome/common), but there are circumstances // where you may add a new one. // // In the rare cicrucmstances where you can't re-use an existing file, // your YYY_message_generator.cc file for a component YYY would contain // the following code: // // Get basic type definitions. // #define IPC_MESSAGE_IMPL // #include "path/to/YYY_message_generator.h" // // Generate constructors. // #include "ipc/struct_constructor_macros.h" // #include "path/to/YYY_message_generator.h" // // Generate destructors. // #include "ipc/struct_destructor_macros.h" // #include "path/to/YYY_message_generator.h" // namespace IPC { // // Generate param traits write methods. // #include "ipc/param_traits_write_macros.h" // #include "path/to/YYY_message_generator.h" // // Generate param traits read methods. // #include "ipc/param_traits_read_macros.h" // #include "path/to/YYY_message_generator.h" // // Generate param traits log methods. // #include "ipc/param_traits_log_macros.h" // #include "path/to/YYY_message_generator.h" // } // namespace IPC // // In cases where manual generation is required, in your XXX_messages.cc // file, put the following after all the includes for param types: // #define IPC_MESSAGE_IMPL // #include "XXX_messages.h" // (... implementation of traits not auto-generated ...) // // Multiple Inclusion // // The XXX_messages.h file will be multiply-included by the // YYY_message_generator.cc file, so your XXX_messages file can't be // guarded in the usual manner. Ideally, there will be no need for any // inclusion guard, since the XXX_messages.h file should consist soley // of inclusions of other headers (which are self-guarding) and IPC // macros (which are multiply evaluating). // // Note that there is no #pragma once either; doing so would mark the whole // file as being singly-included. Since your XXX_messages.h file is only // partially-guarded, care must be taken to ensure that it is only included // by other .cc files (and the YYY_message_generator.h file). Including an // XXX_messages.h file in some other .h file may result in duplicate // declarations and a compilation failure. // // Type Declarations // // It is generally a bad idea to have type definitions in a XXX_messages.h // file; most likely the typedef will then be used in the message, as opposed // to the struct iself. Later, an IPC message dispatcher wil need to call // a function taking that type, and that function is declared in some other // header. Thus, in order to get the type definition, the other header // would have to include the XXX_messages.h file, violating the rule above // about not including XXX_messages.h file in other .h files. // // One approach here is to move these type definitions to another (guarded) // .h file and include this second .h in your XXX_messages.h file. This // is still less than ideal, because the dispatched function would have to // redeclare the typedef or include this second header. This may be // reasonable in a few cases. // // Failing all of the above, then you will want to bracket the smallest // possible section of your XXX_messages.h file containing these types // with an include guard macro. Be aware that providing an incomplete // class type declaration to avoid pulling in a long chain of headers is // acceptable when your XXX_messages.h header is being included by the // message sending caller's code, but not when the YYY_message_generator.c // is building the messages. In addtion, due to the multiple inclusion // restriction, these type ought to be guarded. Follow a convention like: // #ifndef SOME_GUARD_MACRO // #define SOME_GUARD_MACRO // class some_class; // One incomplete class declaration // class_some_other_class; // Another incomplete class declaration // #endif // SOME_GUARD_MACRO // #ifdef IPC_MESSAGE_IMPL // #inlcude "path/to/some_class.h" // Full class declaration // #inlcude "path/to/some_other_class.h" // Full class declaration // #endif // IPC_MESSAGE_IMPL // (.. IPC macros using some_class and some_other_class ...) // // Macro Invocations // // You will use IPC message macro invocations for three things: // - New struct definitions for IPC // - Registering existing struct and enum definitions with IPC // - Defining the messages themselves // // New structs are defined with IPC_STRUCT_BEGIN(), IPC_STRUCT_MEMBER(), // IPC_STRUCT_END() family of macros. These cause the XXX_messages.h // to proclaim equivalent struct declarations for use by callers, as well // as later registering the type with the message generation. Note that // IPC_STRUCT_MEMBER() is only permitted inside matching calls to // IPC_STRUCT_BEGIN() / IPC_STRUCT_END(). // // Externally-defined structs are registered with IPC_STRUCT_TRAITS_BEGIN(), // IPC_STRUCT_TRAITS_MEMBER(), and IPC_STRUCT_TRAITS_END() macros. These // cause registration of the types with message generation only. Note that // IPC_STRUCT_TRAITS_MEMBER() is only permitted inside matching calls // to IPC_STRUCT_TRAITS_BEGIN() / IPC_STRUCT_TRAITS_END(). // // Enum types are registered with a single IPC_ENUM_TRAITS() macro. There // is no need to enumerate each value to the IPC mechanism. // // Once the types have been declared / registered, message definitions follow. // "Sync" messages are just synchronous calls, the Send() call doesn't return // until a reply comes back. Input parameters are first (const TYPE&), and // To declare a sync message, use the IPC_SYNC_ macros. The numbers at the // end show how many input/output parameters there are (i.e. 1_2 is 1 in, 2 // out). The caller does a Send([route id, ], in1, &out1, &out2). // The receiver's handler function will be // void OnSyncMessageName(const type1& in1, type2* out1, type3* out2) // // A caller can also send a synchronous message, while the receiver can respond // at a later time. This is transparent from the sender's side. The receiver // needs to use a different handler that takes in a IPC::Message* as the output // type, stash the message, and when it has the data it can Send the message. // // Use the IPC_MESSAGE_HANDLER_DELAY_REPLY macro instead of IPC_MESSAGE_HANDLER // IPC_MESSAGE_HANDLER_DELAY_REPLY(ViewHostMsg_SyncMessageName, // OnSyncMessageName) // // The handler function will look like: // void OnSyncMessageName(const type1& in1, IPC::Message* reply_msg); // // Receiver stashes the IPC::Message* pointer, and when it's ready, it does: // ViewHostMsg_SyncMessageName::WriteReplyParams(reply_msg, out1, out2); // Send(reply_msg); #ifndef IPC_IPC_MESSAGE_MACROS_H_ #define IPC_IPC_MESSAGE_MACROS_H_ // Can use #pragma once all XXX_messages.h
