java - how to avoid gson tojson recursion -

i have simple class: myobject: - string index; - myobject parent; - list<myobject> childs; i want print stored information json. use tojson function of gson library. due every child has link parent object face infinite loop recursion. there way define gson shall print parent index every child instead of dumping full information? you need use @expose annotation. public class myobject{ @expose string index; myobject parent; @expose list<myobject> children; } then generate json using gson gson = new gsonbuilder().excludefieldswithoutexposeannotation().create(); jsonstring = gson.tojson(data); edit: can dfs parse when convert object. make method like: public void setparents(myobj patent){ this.parent=parent; for(myobj o:children){ o.setparent(this); } } and call root object.

php - Docker - Application source code updates -

i know source code of application should copied using add live inside of docker container. this seems idea, if want able update application source code - twice day, or more often? most viable solution keep source code outside of application. can keep machine running , update source code using git. machine created this: docker run -p 80:80 -v /home/adam/projects/docker-test/src:/var/www/html webserver this means though if controlling machine onprem server, infrastructure on ec2, each time website opened files pulled on internet. what best solution issue? able keep redeploying container updated source code no downtime? actually, should copied copy , not add , in order limit cache invalidation. most viable solution keep source code outside of application. yes, instead of referring through remote source (a git server), have webhook (like github one ) which, on each push git server, pull said repo , keep up-to-date copy of source locally. then mount loca

i have multiple csv files need read r. first column of files contain dates , times, converting posixlt when have loaded data frame. each of csv files have dates , times formatted in same way in excel, however, files read in differently. for example, my file looks once imported: date value 1 2011/01/01 00:00:00 39 2 2011/01/01 00:15:00 35 3 2011/01/01 00:30:00 38 4 2011/01/01 00:45:00 39 5 2011/01/01 01:00:00 38 6 2011/01/01 01:15:00 38 therefore, code use amend format is: data$date <- as.posixlt(data$date,format="%y/%m/%d %h:%m:%s") however, files being read in as: date value 1 01/01/2011 00:00 39 2 01/01/2011 00:15 35 3 01/01/2011 00:30 38 4 01/01/2011 00:45 39 5 01/01/2011 01:00 38 6 01/01/2011 01:15 38 which means format section of code not work , gives error. therefore, there anyway automatically detect format date column in? or, there way of knowing how read, since format of column in excel same on both.

java - ByteBuffer.wrap came out unexpectedly -

i used bytearray create new string, results came out unexpectedly. here code void foo(byte[] data, ...) { bytebuffer bytebuf = bytebuffer.wrap(data, 0, 15); string msg = new string(bytebuf.array()); log.i("foo", string.format("bytearraysize=%d\t\tmsglen=%d,%d", data.length, bytebuf.array().length, msg.length())); } the length of byte array 518400. log info shows: bytearraysize=518400 msglen=518400,518400 rather than bytearraysize=518400 msglen=15,15 what wrong? that expected result. according javadoc bytebuffer.wrap() : wraps byte array buffer. the new buffer backed given byte array; is, modifications buffer cause array modified , vice versa. and bytebuffer.array() : returns byte array backs buffer (optional operation). modifications buffer's content cause returned array's content modified, , vice versa. that means bytebuffer.array() return same array wrapped bytebuffer.wrap() .

Custom data from paypal JS button into webhook -

the javascript paypal button, http://paypal.github.io/javascriptbuttons/ allows custom data sent in data-custom field. when using ipn, these data visible , usable. however, don't find mention of custom data in webhook documentation; expect "sale completed" event receive custom data. so question twofold: has managed data , knows field contains them? is there way simulate this, given webhook simulator not allow field entered? webhooks not support custom data simulator. simulator provides sample of payload event. not allow other data field except url/eventtype. if want use custom data may use them , don't want use live account testing, can try sandbox account , go through flow webhook event type want send custom data. also sample payment.sale.completed reference: { "id": "wh-2wr32451hc0233532-67976317fl4543714", "create_time": "2014-10-23t17:23:52z", "resource_type": "sale",

my language kachhi has no official unicode support have developed own fonts in ttf, otf , svg etc format. run website using same fonts. i want users able write or input in language using fonts (preferably on platforms if not on windows) so how can develop input tool software windows? input custom fonts designed language can pointing out how build own windows ime. link tutorial or books or anything? i apologise if misunderstood question - think may consider using unicode private use area the idea of part of unicode allow situation ( i remember used fictional klingon language @ 1 point ). you can use these zones of unicode-tables, provide input/output mechanisms though traditional unicode methods. obviously enough, without custom font (such 1 you've developed), these sections of table have no meaning.
