Class ResHxLib

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
Copy

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)
Copy

Equality is based on reference equality

Identity hash

Override to return non-null for onHouseKeeping callback

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

Running flag. On startup this flag transitions to true before calling ready and start on the library. On shutdown this flag transitions to false before calling unready and stop on the library.

Logger to use for this library

Programmatic name of the library

Return list of observables this extension publishes. This method must be overridden as a const field and set in the constructor.

Subscribe this library to an observable. The callback must be an Actor instance or Method literal on this class. If callback is a method, then its called on the lib's dedicated background actor. pool. This method should be called in the onStart callback. The observation is automatically unsubscribed on stop. You should not unsubscribe this subscription - it must be managed by the extension itself. See docHaxall::Observables#fantomObserve.

Callback made periodically to perform background tasks. Override houseKeepingFreq to enable the frequency of this callback.

Callback when all libs are fully started. This is called on dedicated background actor.

Callback when associated database rec is modified. This is called on dedicated background actor.

Callback when library is started. This is called on dedicated background actor.

Callback when runtime reaches steady state. This is called on dedicated background actor.

Callback when library is stopped. This is called on dedicated background actor.

Callback before we stop the runtime This is called on dedicated background actor.

Database record which enables this library and stores settings. This field may be overridden with a haystack::TypedDict subclass. Also see docHaxall::Libs#settings.

Runtime

Return list of services this library publishes. This callback is made during initialization and each time a lib is added/removed from the runtime.

Observable subscriptions for this extension

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

Return name

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.

Web service handling for this library

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.
