scala - Apply a sequence of functions to value and get the final result -

i wish apply sequence of functions object (each of functions may return same or modified object) , ultimate result returned last function.

is there idiomatic scala way turn (pseudocode):

val pipeline = listmap(("a" -> obj1), ("b" -> obj2), ("c" -> obj3)) 

into this?

val initial_value = something("foo", "bar") val result = obj3.func(obj2.func(obj1.func(initial_value))) 

the pipeline initialized @ runtime , contains undetermined number of "manglers".

i tried foreach requires intermediate var store result, , foldleft works on types of listmap, while initial value , result of type something.

thanks

this should it:

 pipeline.foldleft(initial_value){case (acc, (k,obj)) => obj.func(acc)} 

no idea why pipeline contains pairs, though.
