CMake to compile java code -

-

is possible use cmake compile , run java code?

from command line commands write on terminal is:

javac -classpath theclasspath mainclass.java

java -classpath theclasspath mainclass

if so, please give me idea of how can achieved?

ps: not want generate jar file; compile java class , if possible run it.

thanks.

update: have changed command. not know why additional text not displayed. might because used "<" , ">".

cmake has limited support compiling java code , executing java class files.

the standard module findjava can used find jdk installed on local machine. standard module usejava provides few functions java. among function add_jar compile java source files jar file.

here small example demonstrates how use add_jar. given java sample source file helloworld.java:

public class helloworld {     public static void main(string[] args) {         system.out.println("hello, world!");     } }

the following cmake list file compile helloworld.java jar file helloworld.jar , add cmake test runs jar jvm:

cmake_minimum_required (version 2.8)  find_package(java required) include(usejava)  enable_testing()  project (helloworld)  set(cmake_java_compile_flags "-source" "1.6" "-target" "1.6")  add_jar(helloworld helloworld.java)  get_target_property(_jarfile helloworld jar_file) get_target_property(_classdir helloworld classdir)  message(status "jar file ${_jarfile}") message(status "class compiled ${_classdir}")  add_test(name testhelloworld command ${java_java_executable} -cp ${_jarfile} helloworld)

the cmake variable cmake_java_compile_flags can used specify compile flags. side effect add_jar command set target properties jar_file , classdir can used obtain path generated jar file , compiled class files directory, respectively.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
