AbstractMSpecArgs
Assembled XetoSpec (stub only in AST until Assemble step)
Binding for spec type
Base spec or null if this sys::Obj itself
Lookup enum item by its key - raise exception if not enum type
Optionalchecked: booleanReturn if spec inherits from that from a nominal type perspective. This is the same behavior as Spec.isa, just using CSpec (XetoSpec or AST)
Effective meta
Return if effective meta has given slot name
Return item for seq/ref
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)
Type of the spec or if this a type then return self
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.
MSpecFlags bitmask flags
Flavor: type, global, meta, slot
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.
Is there one or more effective slots
Ref for qualified name
Is base sys::And
Return if this an AST ASpec

Inherits from sys::Query without considering And/Or
Inherits from sys::Ref without considering And/Or
Inherits from sys::Scalar without considering And/Or
Is this the sys::Self spec
Is this spec in the sys library
Simple name
Qualified name
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.
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.
