Constructor Details

#initialize(scope, resources) ⇒ FixedSetCollector

Creates a FixedSetCollector using the AbstractCollector constructor to set the scope. It is not possible for a collection to have overrides in this case, since we have a fixed set of resources that can be different types.

Parameters:

  • resources (Array) —

    the fixed set of resources we want to realize
