collection - Object collections

Several objects use collections as a property to help find objects that satisfy certain criteria. Collections are typically built at initialization, although that can be run at any during a simulation if needed.

A collection is specified as string with one or more filtering elements. For example,

 class=house

would collect all the objects that have the class house.

Only properties that are invariant during a simulation may be used in a collection. The following properties are supported:

  • id
  • class
  • isa
  • module
  • groupid
  • rank
  • parent
  • insvc
  • name
  • latitude
  • longitude
  • clock
  • insvc
  • outsvc
  • flags

The following operators are supported:

  • AND (can also be written as "and" or ";")

Note that the "OR" operator is not supported at this time.
