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.
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.
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.

StaticpointUser level-8 manual auto (override release) of writable point. See pointWrite.
StaticpointEvaluate a point conversion. First parameter is point to test (anything accepted by toRec) or null to use empty dict.
Examples:
pointConvert(null, "+ 2 * 10", 3)
pointConvert(null, "hexToNumber()", "ff")
pointConvert(null, "°C => °F", 20°C)

StaticpointUser level-1 manual override of writable point. See pointWrite.
StaticpointUser level-8 manual override of writable point. If duration is specified it must be a number with unit of time that indicates how long to put the point into override. After the duration expires, the point is set back to auto (null). See pointWrite.
StaticpointStaticpointSet the relinquish default value (level-17) of writable point. See pointWrite.
StaticpointReturn grid of thermistor table names as grid with one name
column
StaticpointSet a writable point's priority array value at the given level. The point may be any value accepted by toRec. Level must be 1 to 17 (where 17 represents def value). The who parameter is a string which represent debugging information about which user or application is writing to this priorirty array level. If who is omitted, then the current user's display string is used
StaticpointReturn the current priority array state of a writable point. The point may be any value accepted by toRec. The result is returned grid with following columns:
StatictoMap a set of recs to to a grid of devices. The recs
parameter may be any value accepted by toRecList().
Return empty grid if no mapping is found. The following
mappings are supported:
device tag are mapped as themselvesdeviceRef tag are mapped to their parent devicesite are mapped to devices with parent siteRefspace are mapped to devices with parent spaceRefequip are mapped to devices with parent equipRefExamples:
read(site).toDevices // return children devices within site
read(space).toDevices // return children devices within space
read(equip).toDevices // return children devices within equip
read(point).toDevices // return point's parent device
StatictoMap a set of recs to to a grid of equips. The recs
parameter may be any value accepted by toRecList().
Return empty grid if no mapping is found. The following
mappings are supported:
equip tag are mapped as themselvesequipRef tag are mapped to their parent equipsite are mapped to equip with parent siteRefspace are mapped to equip with parent spaceRefExamples:
read(site).toEquips // return children equip within site
read(space).toEquips // return children equip within space
read(equip).toEquips // return equip itself
read(point).toEquips // return point's parent equip
StatictoGiven a site, space, equip, or point rec, get its occupied point. The following algorithm is used to lookup the occupied point:
If there are no matches or multiple ambiguous matches, then return null or raise an exception based on checked flag.
