hashmap - Scala - reformatting hash-map -


i have python code processes complex hashmap (example input), restructures , creates (example output) simplified version of it. i'm looking best way tackle scala, i.e. built in or external libs? i'm new scala , getting grips it, guidance here helpful.

this easy using python , i'm hoping scala.

input:

data_in = {     'map': {         'stats': {             'uphosts': u'3',             'timestr': u'thu mar 20 18:18:09 2014',             'downhosts': u'0',             'totalhosts': u'3',             'elapsed': u'1.71'         },         'scaninfo': {             u'tcp': {                 'services': u'80,443',                 'method': u'syn'             }         },         'command_line': u'command goes here'     },     'scan': {         u'2a00:2384:0:208f::15': {             'status': {                 'state': u'up',                 'reason': u'nd-response'             },             'hostname': u'static.xyz.com',             'vendor': {                 u'00:0c:67:99:6f:96': u'vmware'             },             'addresses': {                 u'mac': u'00:gf:29:99:6d:96',                 u'ipv6': u'a848:2384:0:3456::15'             },             u'tcp': {                 80: {                     'product': '',                     'state': u'open',                     'version': '',                     'name': u'http',                     'conf': u'3',                     'extrainfo': '',                     'reason': u'syn-ack',                     'cpe': ''                 },                 443: {                     'product': '',                     'state': u'open',                     'version': '',                     'name': u'https',                     'conf': u'3',                     'script': {                         u'ssl-cert': u'place holder'                     },                     'extrainfo': '',                     'reason': u'syn-ack',                     'cpe': ''                 }             }         },         u'2a00:2384:0:208f::16': {             'status': {                 'state': u'up',                 'reason': u'nd-response'             },             'hostname': u'static.edf.com',             'vendor': {                 u'00:0c:55:ae:33:ff': u'vmware'             },             'addresses': {                 u'mac': u'00:54:29:fg:55:0f',                 u'ipv6': u'8938:8584:0:8685::16'             },             u'tcp': {                 80: {                     'product': '',                     'state': u'open',                     'version': '',                     'name': u'http',                     'conf': u'3',                     'extrainfo': '',                     'reason': u'syn-ack',                     'cpe': ''                 },                 443: {                     'product': '',                     'state': u'open',                     'version': '',                     'name': u'https',                     'conf': u'3',                     'script': {                         u'ssl-cert': u'place holder'                     },                     'extrainfo': '',                     'reason': u'syn-ack',                     'cpe': ''                 }             }         }     } }

required output:

data_out_1 = [     {'address': u'2a00:2384:0:208f::15',   'hostname': u'static.xyz.com',   'ports': {80: {'reason': u'syn-ack', 'state': u'open'},             443: {'reason': u'syn-ack',                   'ssl_cert': u'place holder',                   'state': u'open'}}},     {'address': u'2a00:2384:0:208f::16',   'hostname': u'static.edf.com',   'ports': {80: {'reason': u'syn-ack', 'state': u'open'},             443: {'reason': u'syn-ack',                   'ssl_cert': u'place holder',                   'state': u'open'}}}]

that isn't typesafe.

hashmaps can't store different types of data*. start creating datastructures hold input data (case classes here).

so stats object might 

case class stats(uphosts: int, timestr: datetime, downhosts: int, totalhosts: int, elapsed:double)
  • ignoring subtyping here moment.
