Attributes of an object

Syntax: attr x, attr[x]

Returns the attributes of x. It can be applied to all data types. The possible attributes are:

  • `s# sorted
  • `u# unique (hash table)
  • `p# partitioned (grouped)
  • `g# true index (dynamic attribute): enables constant time update and access for real-time tables

The result is a symbol atom and is one of `s`u`p`g` with ` meaning no attributes are set on the argument.
