javascript - AngularJS watch element height change in directive -


i realize there several similar questions, checked them don't seem cover case. have fluid flexbox-based layout. of window used container block, shrinks when siblings appear. like

<body>     <div class="menu"></div>     <div class="contact"></div>     <div class="container"></div> </body>

the container height not changed directly, it's recalculated browser when toggle other elements, such menu.

i want watch container height , recalculate elements in directive. watch height this

scope.$watch(()=>parentelement.prop('offsetheight'), resize); resize=()=>{console.log('resize called');};

problem resize triggered on next digest. when toggle menu first time nothing happens, on second resize called previous (first call) dimensions , on.

i realize it's because browser resize not trigger digest, functions show menu use $rootscope, digest call should occur.

is there way watch element dimensions in case?

upd: if remove watch filter , listen every event, resize function when trigger menu (obviously it's rootscope caused call) parent element height still old. maybe there way defer watcher? ideally not timeout event.

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
