java - Compiling without assertions -

-

i know assertions can enabled/disabled @ runtime debugging , production, respectively. found assertions increase size of generated binary (about 100-200 bytes in example below).

in c , c++, can @ compile time having #define ndebug before #include <assert.h>.

is there way java compiler automatically this? i'd leave them in source code debugging purposes later on. don't want resultant binary larger necessary (we have size limit design requirement).

c code:

//#define ndebug #include <assert.h>  int main(void) {     assert(0); // +200 bytes without ndebug, 0 ndebug     return 0; }

java code:

public class test {     public static void main(string[] args) {         assert(system.nanotime()==0); // increases binary size 200 bytes     } }

in response bn.'s answer:

public class test2 {     public static final boolean assertions = false;      public static void main(string[] args) {         if(assertions) {             assert(system.nanotime()==0);         }     } }

edit: in fact, seems me enabling/disabling more useful compile-time feature run-time. mean, how many end users enable them? far programmer concerned during debug process, he/she recompiling code anyways.

personally not following because of complexity added source code javac generated exact same intermediate code main in following 2 fragments:

conditional asserts

class c {     public final static boolean assertions = false;      public static void main(string[] args) {         if(assertions) {             assert(system.nanotime()==0);         }     } }

no asserts

class c {     public static void main(string[] args) {     } }

compiled code

  public static void main(java.lang.string[]);     code:        0: return             linenumbertable:       line 3: 0

edit

its not end users enable them, customer support tells end user enable them. wish though enabled, not disabled, default.

django - How can I change user group without delete record -

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...

java - Need to add SOAP security token -

-
i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
