Check that the xeto can be loaded or raise exception
Return a negative integer, zero, or a positive integer if this object is less than, equal to, or greater than the specified object:
this < that => <0
this == that => 0
this > that => >0
This method may also be accessed via the < <= <=> >= and >
shortcut operators. If not overridden the default
implementation compares the toStr
representations. Also see docLang.
Examples:
3.compare(8) => -1
8.compare(3) => 1
8.compare(8) => 0
3 <=> 8 => -1 // shortcut for 3.compare(8)
Compare this object to the specified for equality. This
method may be accessed via the == and != shortcut operators.
If not overridden the default implementation compares for
reference equality using the === operator. If this method
is overridden, then hash() must also be overridden such that
any two objects which return true for equals() must return
the same value for hash(). This method must accept null and
return false.
This method should be called at periodically to execute components and check timers. The frequency this method is called determines the smallest timer increment. For example if its called every 100ms then timers will only fire as fast as 100ms.
Optionalnow: DateTimeReturn 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.
Initialize the root - this must be called exactly once during initialization
Has this space been started, but not stopped yet
Load tree from xeto instances
Xeto namespace for this space

Root component
Save tree to eto instances
Start space. Sublasses must begin to call checkTimers
Stop space. Sublasses must cease to call checkTimers
Get an immutable representation of this instance or throw NotImmutableErr if this object cannot be represented as an immutable:
Return a string representation of this object.
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])
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.
Modify the namespace on the fly. Every component in the current tree must map to a spec in the new namespace or exception is raised. This update does not check that components validate against the new specs.
Current version of component changes
This method called whenever an it-block is applied to an
object. The default implementation calls the function with this,
and then returns this.
StaticechoWrite 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.

CompSpace manages a tree of components. It is the base class for different component applications for control, Ion UI, and remote programming
