Class Property

Compare based on ordinal value.

Enums are only equal if same instance using ===.

Return a unique hashcode for this object. If a class overrides hash() then it must ensure if equals() returns true for any two objects then they have same hash code.

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 the programatic name for this enum.

Return ordinal value which is a zero based index into values.

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.
