arrays - Storing values obtained from for each loop Scala -


scala beginner trying store values obtains in scala foreach loop failing miserably. basic foreach loop looks currently:

order.orderlist.foreach((x: orderref) => {    val references = x.ref}))

when run foreach loop execute twice , return reference each time. i'm trying capture reference value returns on each run (so 2 references in either list or array form can access these values later)

i'm confused how go doing this...

i attempted retrieve , store values array when ran, array list doesn't seem hold values.

this attempt:

val newarray = array(order.orderlist.foreach((x: orderref) => {     val references = x.ref   }))   println(newarray)

any advice appreciated. if there better way achieve this, please share. thanks

use map instead of foreach

order.orderlist.map((x: orderref) => {x.ref}))

also val references = x.ref doesn't return anything. create new local variable , assign value it.

python - Best design pattern for collection of objects -

i have following architecture: +-----------------+ | collection | | | | | | | | | +-----------------+ | ^ | | create() | | | | v | getitem(b) +------------+ | | item | | | | | | +------+ | | +------------+ a class managing collection of items, creates items. , these items may need other items collection. the actual code in python, , collection passes parameter created item . see it, bad practice. improvement can see pass few functions of collection needed item , instead of whole instance. for example: class collection: getitem(self, id): ... createitem(self, id): item = item(id, self) # <-- pass self ... class item: __init__(self, id, col): ... col.getite...
