本程序功能是将c++源码转换为java源码,转好代码将全部放在目标目录下的java文件夹中. 我的主要目的是方便一些算法的迁移,当然也希望能出一个java源码转成c++的,这是求之不得的事,虽然有点复杂,就等待大家的智慧了. 这个软件也只是做了一些基本的直译,很多类还是需要自己手动转换,毕竟方法名称都不大一样, 比如vector转换成ArrayList,同样添加元素前者是push_back,而后者是add,此外有一点特别注意的地方,c++的string截取字串方法substr(strat,offset)和java的String方法substring(start,end)有很大差别,我就调试了好久才发现. 有什么好的方法来改进程序,希望联系本人javaloveme@gmail.com.

README.md

This project aims to convert C++ code to high level Java source code. Where that is not possible, a TODO should appear in the generated source code.

The project is about three quarters of the way to an initial release. The below items will not be handled by the initial release:

• goto statement
• untyped malloc
• template code generation (generics to be used instead).
• C++/C std lib
• order of operation differences
• platform dependent/undefined behavior
• unions
• dynamic cast and other RTTI features
• multiple inheritance
• C++11 features
• overloaded operator new and operator delete memory management

Everything else should work with the initial release.

The following lines give an indication of what generated code using pointers looks like.

// Test plain assignment. f[4] = 111; *f = 112; (((*(f + 2)))) = 113; *(f--) = 114; // Test compound assignment. f[1] *= 3; (*f) += 4; // Test pointer comparison f < &f[1]; &f[0] == f; // Test addressof ptr &f;

f.ptrOffset(4).set(111); f.set(112); ((((f.ptrOffset(+2))))).set(113); (f.ptrPostDec()).set(114); f.ptrOffset(1).set(f.ptrOffset(1).get() * 3); (f).set((f.get()) + 4); f.ptrCompare() < f.ptrOffset(1).ptrCompare(); f.ptrOffset(0).ptrCompare() == f.ptrCompare(); f.ptrAddressOf();

This fork will build with Maven. Eclipse CDT is not in Maven central, or any repository I could find, but for your convenience, private copies of certain JARS are shipped in the lib/ directory:

• org.eclipse.cdt.core_5.4.1.201209170703.jar
• org.eclipse.equinox.common_3.6.100.v20120522-1841.jar
• com.ibm.icu_50.1.1.v201304230130.jar (I needed it at run-time once to fix a logging error)

Please note these are from a separate project with separate licenses.

These are the JAR files I use to get this code to run. They are from Eclipse Juno (4.2.x) and CDT 8.1.1 for Eclipse Juno. Additionally, jOOR is required by the runtime template handling code.

• Eclipse downloads
• CDT downloads
• jOOR at Github
• org.eclipse.cdt.core_5.4.1.201209170703.jar
• org.eclipse.equinox.common_3.6.100.v20120522-1841.jar
• joor-0.9.3.jar

This project is licensed under the Apache license. The CDT walking code is based loosely on code I found (and lost the url) on the web (also licensed under the Apache license).

This is an incomplete and fluid list of items that need doing before the initial release.

• General
  • Lots more assertions
  • Destructor calls on static duration objects
  • Cast operators other than C style cast should not resolve overloaded operator cast
  • Basic type classes other than MInteger
  • Global variables
  • Templates
  • Should be able to take the address of an enumerator
  • Putting in comments/defines from original
  • A lot of work on multi dimension arrays.
  • cleanup cpptojavatype method.
  • function pointers.
  • typed malloc.
  • testing cleanup.
  • making logger useful.
  • relacing deprecated methods.
  • make lists.
  • correct names (camel case, capitalized classes etc.)
  • Varargs.
  • Bracketed expressions
  • Special case this pointer and void pointer.
  • exact bit position for bitfield.
  • Recursively evaluate templates and generate expanded cpp code.
  • Generate implicit special methods and output cpp code.
  • Record if a basic variable(int, bool, etc) has its address taken so we can skip objectifying it if it does not.

  File extension : Convert CPP to JAVA

  The .CPP format belongs to the C++ programming language and is used to store source code. These source code files are often part of a collection/project. When compiled, these files are built in to executable programs.

  File extension Java Source Code (.JAVA)

  Question: What is an JAVA File?
  Have you found, downloaded or received an JAVA file, but don’t know which software program is required to open it? Before attempting to open an JAVA file, you’ll need to determine what kind of file you are dealing with and whether it is even possible to open or view the file format. Answer: Files which are given the .JAVA extension are known as Java Source Code files, however other file types may also use this extension. If you are aware of any additional file formats that use the JAVA extension, please let us know. How to open a JAVA file:
  The best way to open an JAVA developer file is to simply double-click it and let the default assoisated application open the file. If you are unable to open the file this way, it may be because you do not have the correct application associated with the extension to view or edit the JAVA file. This developer file format was added to our database by a visitor to this site, but no additional information was provided. We have yet to investigate this file type further, or there was not enough information available at the time to report accurately on the format. Please check back soon for more information as we are constantly updating our file descriptions based on search frequency. Tip: Try to open the JAVA file using a text-editor such as Notepad, as many file types contain simply contain unformatted plain-text and can viewed correctly using this method.
