  # if a new container is set, make sure to disconnect from the old one.
  # note that _set_container will never be called for the container and the role
  # which are currently set because the accessor methods in BuilderExtensions
  # block setting/adding a value which is already present.
  # (it may be called for the same container with a different role, a different container
  # with the same role and a different container with a different role, though)
  # this ensures, that disconnecting for the current container doesn't break
  # a new connection which has just been set up in the accessor methods.

#eAllContents(&block) ⇒ Object

if a block is given, calls the block on every contained element in depth first order. if the block returns :prune, recursion will stop at this point.

if no block is given builds and returns a list of all contained elements.
