New Java Array of Strings in Nashorn -


i'm writing high-performance nashorn application, , i'd find equivalent new string[]{"foo", "bar", "noise"} within javascript. cost of converting javascript array java array prohibitively expensive, shows on every flame graph.

the best i've found point is: {var stringarray = java.type('java.lang.string[]');"); var arr = new stringarray(3)); var arr[0] = 'foo'; var arr[1] = 'bar'; var arr[2] = 'noise'; arr;}

but that's super ugly. best syntax available me?

thanks!

you can using java.to():

java.to(["foo", "bar", "noise"],"java.lang.string[]");

if code works (it me, tested jjs 1.8.0_51), can create function ease code readability. this:

function tojavastringarray(a) {   return java.to(a,"java.lang.string[]"); }

java - Using Spring @Transactional with a combination of readOnly and write, when does this entity get committed? -

given class callingclass { @autowired someservice someservice; doit() { someservice.readonlycall(); } } @transactional(readonly = true) class someservice { @autowired anotherservice anotherservice; readonlycall() { // logic may do... anotherservice.writecall(); } } class anotherservice { @transactional // not readonly writecall() { // save entity } } will entity committed database when writecall method exits or when readonlycall method exits? and how can modify commits after writecall method? the entity not committed database in both method exits. because your someservice class has read-only (which have specify). set flushmode.never prevent commit transaction your someservice class , anotherservice class has required propagation type(which default , have not specify other type both class). create new transaction if doesn't exist use current transaction if there is. in case someservice class begin transaction read-only , an...
