serialization - Serializing a lucene query into JSON? - is there best practice serializing lucene queries json format? saw elastic search query dsl, looks strays lucene terminology. also, lucene appears moving away maintaining serialization code. i looking have "standard" format in json. need able save query, when users saving queries on web ui, not entering title:matrix . have able search saved searches, edit saved searches. nice if there standard json format representing query. lucene query. i know little of elasticsearch i'm guessing doing (also) because back upwards query functionality other lucene does. if need marshall/unmarshall query, treat whole single unescaped string. if want break downwards key-value (field name/value) elements, don't forget can have conjuction/disjunction/etc. not trivial. as comment on serialization code - don't think applies queries. query has abstract tostring(string field) method each query subclass sh

How to free memory using Java Unsafe, using a Java reference? - java unsafe class allows allocate memory object follows, using method how free memory allocated when finished, not provide memory address... field f = unsafe.class.getdeclaredfield("theunsafe"); //internal reference f.setaccessible(true); unsafe unsafe = (unsafe) f.get(null); //this creates instance of player class without initialization player p = (player) unsafe.allocateinstance(player.class); is there way of accessing memory address object reference, maybe integer returned default hashcode implementation work, do... unsafe.freememory(p.hashcode()); doesn't seem right how... "memory address" of object reference not create sense since objects can move across java heap. you cannot explicitly free space allocated unsafe.allocateinstance , because space belongs java heap, , garbage collector can free it. if want own memory management outside java heap, m
