naming conventions - Why is Multimap not camel cased? -


this 1 annoys me (and colleague).

it's not

  • hashmap
  • treemap
  • org.apache.commons.collections.multimap
  • etc.

so why didn't notice naming convention flaw or there intention behind typo?

the word "multimap" (one word, entirely lowercase) refers specific data structure. it's different "map", data structure. since they're different data structures, have different names.

the map interface use in java chosen name associative array, known "map", "dictionary", "hash", etc. likewise, guava's multimap interface representation of multimap data structure.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
