PartSet

semagrams.acsets.PartSet

case class PartSet(nextId: Int, ids: Seq[Id], acsets: Map[Id, ACSet])

Storage class for the parts corresponding to an Ob in a schema.

This is immutable; methods that logically mutate simply return new objects.

Attributes

acsets: The subacset corresponding to each id
ids: The ids of all the parts added so far. This is a Seq because we care about the ordering; when the ACSet is displayed this ordering is used when two sprites overlap.
nextId: The id to assign to the next part added

Adds a single part with subacset acs, returns its id.

Add multiple new parts, with subacsets given in partacsets.

Returns a sequence of the ids of the added parts.

Move the id i to the front of the list of ids.

This is used, for instance, when dragging a sprite so that the sprite goes over the other parts.

Move the id i to the index j in the list of ids.

This is used, for instance, when setting the position of a port.

Remove the part with id i

Set the subacset corresponding to i to acs
