MongoDB & Java Driver: Range Query -



MongoDB & Java Driver: Range Query -

i have database of documents contain numerical field x. attempting write query returns specified number of documents x fields closest given value y.

e.g. list of x documents [1, 4, 9, 2, 5, 4, 6, 8, 9, 10, 23, 2] y 5, specified number of results homecoming 6 homecoming [4, 4, 5, 6, 8, 9]

my initial thought of documents, sort result set x, , trim excess entries around y. i'm not sure how implement "trimming" functionality in mongo, however.

how can go crafting query using java driver this?

there nil mongodb help you. have implement such filtering on application level or perhaps utilize map-reduce standard client-side query api not help here (unlikely implement using sql).

java mongodb

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? -

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? - what difference between "some" == "some\0" , strcmp("some","some\0") in c++? why if("some" == "some\0") returns false , if(!strcmp("some","some\0")) returns true ? see next diagram. shows 2 strings in memory, content in box, beside box you'll see address of each one. when you're doing if("some" == "some\0") comparing addresses. translated if (0xdeadbeef == 0x0badcafe) false. when utilize strcmp , compare content of each box until reach \0 in each of them. that's why sec test returns true. if alter first test if("some" == "some") compiler may potentially see same strings , store them once. means test transform if (0x0badcafe == 0x0badcafe) true. c++ string comparison

actionscript 3 - Flex: moving a point with rotation doesnt change the point XY? -

actionscript 3 - Flex: moving a point with rotation doesnt change the point XY? - i have follow issue : i have point setted @ border on component, changed transform point center of component in order match component rotation. the of import part when seek point xy after rotation - remains same before rotation. how xy, after rotation ( changeing point.rotation property specific degrees of rotaion ) if want point after rotation, cos(r) * x, sin(r) * y easiest way. if want point after transformations, should able utilize displayobject.transform.transformpoint(x, y) . there's displayobject.localtoglobal . in case phone call localtoglobal(x, y) , localtoglobal(0, 0) , calculate difference. see transform livedocs , displayobject livedocs flex actionscript-3
