Specific embodiment
In order to keep the contents of the present invention more clear and understandable, combined with specific embodiments below with attached drawing in of the invention
Appearance is described in detail.
In the present invention, type system is generated using the SFINAE characteristic of C++ template system, is defined according to conventional structure body
Mode define protocol definition, and indicate the field that needs serialize, after binding the protocol number of this agreement, local number can be loaded
According to or network flow, when serialize to object/unserializing handles and use in C++ and Lua, and being communicated with Lua without
All types need to be registered.
It, can be literary by the protocol configuration automatically generated in the small version updating for not updating C++ code more new resources
Part, modifies to unaware agreement or newly-increased agreement uses in Lua file, and the logic of original C++ code is unaffected.
Fig. 1 schematically shows flow chart according to the preferred embodiment of the invention.Process shows sequence of the invention
The specific embodiment of column method and the network communication method based on serializing.
As shown in Figure 1, preferred embodiment includes: according to the present invention
First step S1: in such a way that conventional structure body defines, the definition of agreement is abstracted into type system, and refer to
The bright field for needing to serialize；
For example, the step of indicating the field that needs serialize includes: the agreement and protocol fields information for serializing needs
The example for being abstracted into corresponding types system.Alternatively, for example, the step of indicating the field that needs serialize includes: will be specific
It is macro to be included in structural body definition.
Second step S2: the type system of definition and specific protocol number are bound；
In specific example, for the two above-mentioned steps, for example, being firstly added associated documents (for example, #Include
" SDReflect.h "), protocol type (support inherit and polymorphic) is then defined as common definition structural body, has defined it
It is macro to indicate field that needs serialize to structural body to increase a RTTI for sample for reference (demo) afterwards, then in corresponding cpp
The type system of definition and specific protocol number are bound by way of registering loader (loader) in file, so that it may with
The heart is desired serialize or communicate with networking client.
Wherein, it supports to inherit and polymorphic mode includes: the type loader branch for serializing type and being generated by compiling duration
Succession and polymorphic is held, does not need to modify configuration file by hand and realizes and inherit and polymorphic feature.
Third step S3: it is realized using the SFINAE characteristic of C++ template system to the automatic of protocol fields and nested agreement
Serializing processing is with the structural body of formation sequence；
Further, in order to which agreement or type are carried out seamless communication between C++ network-side and Lua network-side, may be used also
To execute following four steps S4 and the 5th step S5.
Four steps S4: the function for public access rights that leading-out needle defines the class of Lua；
Specifically, for example, (can determine if necessary needing to export the method for defining public access rights to the class of Lua
An adopted general communication functions, parameter type is base class), operation can automatically generate after generating the python file that Lua is bound
With the communication cryptology of Lua, derived function free translation sequence structural body between Lua and C++ is then rested against.
5th step S5: the structure of derived function translation sequence between Lua network-side and C++ network-side is utilized
Body.
Further, agreement is updated by way of more new configuration file in order to realize, following 6th steps can also be performed
Rapid S6.
6th step S6: modification protocol definition, then at log-in protocol modify default parameters, by operation client come
Configuration file is automatically updated, the configuration file of update is put into the more new version of agreement.
In this manner it is possible to use new agreement in Lua, and do not need to update the .so file of C++ compiling at this time, it is former
There is the protocol definition in .so file still can normally forward.Calling code (the python of C++ can be generated by Python
The effect of code is analytic definition header file, automatically in C++ type and other C++ functions for needing to export in Lua infuse
In volume to Lua virtual machine), it does not hereafter need to write by hand for every kind of serializing type or using generator registration type to Lua
The mechanism of all sequences structure can be transmitted mutually with Lua.It can be matched by automatically generating when C++ code cannot be updated
The mode for setting file realizes newly-increased or change protocol definition and may be implemented and definition in original .so and logic and deposit and mutual not shadow
Loud mechanism.
As a result, in the present invention, client and the direct definition structure body of server-side, and which field is indicated in structural body
It is to need to serialize, it can directly carry out communication and seamless interacted with Lua script.In the feelings that cannot update C++ code
Change Lua protocol definition is realized by change configuration file under condition and increases new agreement.
In the present invention, C++ uses template SFINAE characteristic implementation type system, can be fixed in compiling duration automatic identification type
Justice and the adjacent field of merging treatment, greatly improve performance；The succession of body support structure and polymorphic, supported protocol and standard
The unlimited nesting of template library (STL, Standard Template Library) container.Using the solution of the present invention, passes through and configure
Former C++ agreement existing logic is not influenced when file modification Lua agreement.Moreover, the end Delphi is by pre-saving reflective information
Improve performance.
In addition, can be used and marked in position binary bits (bit) of serializing head Sign field in specific example
The mode of note realizes dynamic head-coating structure, to make to need to guarantee that the volume of each packet is as small as possible and special in a large amount of parcels
Situation needs the demand of super large packet all to be met.
In the case where hand trip is inconvenient to update binary code, the present invention can be modified by way of more new configuration file
Or newly-increased agreement is used for Lua file, the version updating mode of adaptation mobile phone environment that can be more flexible compared to other solutions.
In the present invention, to include: serializing/antitone sequence module use template in compiling duration to the mode of ergodic sequence field
SFINAE characteristic, which generates type loader system and does not need repeatedly to jump judgement in the runtime, directly to carry out sequence to field
Column/unserializing feature is eliminated in the runtime by way of multiple " if else " sentences or hash table to difference
Type field carries out handling caused performance cost.
In addition, it should be noted that, unless stated otherwise or point out, the otherwise term " first " in specification, "
Two ", the descriptions such as " third " are used only for distinguishing various components, element, the step etc. in specification, each without being intended to indicate that
Component, element, the logical relation between step or ordinal relation etc..
