Ruby's inject method like for Scala collections: any idea? -

i'm trying figure out how in scala

i have

list( myobject(id, name, status), ..., myobject(id, name, status) ) 

and want apply function collection in order obtain list containing "id" properties of myobjects

list( id1, id2, .., idn) 

i'd similar ruby's inject method:

list.inject( [] ){ |lst, el| lst << el } 

any suggestion?

you can use list's (actually, traversablelike's) map function, follows: list.map(_.id). there wealth of useful methods available scala collection classes - worth learning.
