Groovy - How to Build a Jar -

-

i've written groovy script has dependency on sql server driver (sqljdbc4.jar). can use groovywrapper (link below) compile jar, how can dependencies jar? i'm looking "best practice" sort of thing.

http://groovy.codehaus.org/wrappinggroovyscript

both of replies below have been helpful, how can signed jar files? instance:

exception in thread "main" java.lang.securityexception: invalid signature file d igest manifest main attributes

in groovy wrapper script, you'll see line near bottom:

// add more jars here

that's can add dependencies. if jar file in same directory you're building from, add line this:

zipgroupfileset( dir: '.', includes: 'sqljdbc4.jar' )

then rerun script , jar include classes sqljdbc4.jar.

edit:

if jar file depend on signed , need maintain signature, you'll have keep external jar. can't include jar files inside of other jar files without using custom classloader. can, however, specify dependency in manifest avoid having set classpath, i.e. jar still executable java -jar myjar.jar. update manifest section in wrapping script to:

manifest {     attribute( name: 'main-class', value: mainclass )     attribute( name: 'class-path', value: 'sqljdbc4.jar' ) }

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.
