Class Uuid

Return if this Obj is immutable and safe to share between threads:

• an instance of a const class
• the result of toImmutable on List, Map, or Buf
• a Func object may or may not be immutable - see sys::Func.
• other instances are assumed mutable and return false

Get an immutable representation of this instance or throw NotImmutableErr if this object cannot be represented as an immutable:

• if type is const, return this
• if already an immutable List, Map, Buf, or Func return this
• if a List, then attempt to perform a deep clone by calling toImmutable on all items
• if a Map, then attempt to perform a deep clone by calling toImmutable on all values (keys are already immutable)
• some Funcs can be made immutable - see sys::Func
• if a Buf create immutable copy, see sys::Buf
• any other object throws NotImmutableErr

Trap a dynamic call for handling. Dynamic calls are invoked with the -> shortcut operator:

a->x        a.trap("x", null)
a->x()      a.trap("x", null)
a->x = b    a.trap("x", [b])
a->x(b)     a.trap("x", [b])
a->x(b, c)  a.trap("x", [b, c])
Copy

The default implementation provided by Obj attempts to use reflection. If name maps to a method, it is invoked with the specified arguments. If name maps to a field and args.size is zero, get the field. If name maps to a field and args.size is one, set the field and return args[0]. Otherwise throw UnknownSlotErr.

Get the Type instance which represents this object's class. Also seeType.of or Pod.of.

This method called whenever an it-block is applied to an object. The default implementation calls the function with this, and then returns this.

Write x.toStr to standard output followed by newline. If x is null then print "null". If no argument is provided then print an empty line.
