    Methods

    • 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)

      Parameters

      Returns number

    • 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.

      Parameters

      Returns boolean

    • If the current ns prefix is mapped in the given map, then return a new Iri that is the expansion of the prefix. Otherwise, return this.

      Parameters

      • prefixMap: Map<string, string>

      Returns Iri

    • 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.

      Returns number

    • Is this a blank node?

      Returns boolean

    • 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

      Returns boolean

    • Get the IRI local name

      Returns string

    • Get the IRI namespace

      Returns string

    • If the current ns contains a prefix in the given map, then return a new Iri that uses the prefix. Otherwise, return this.

      Parameters

      • prefixMap: Map<string, string>

      Returns Iri

    • 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

      Returns Readonly<this>

    • Return a string representation of this object.

      Returns string

    • 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.

      Parameters

      Returns JsObj

    • Get the Type instance which represents this object's class. Also seeType.of or Pod.of.

      Returns Type

    • Get the Iri as a Uri. Note, because of Uri normalization it is possible that two un-equal Iris will yield equivalent Uris

      Returns Uri

    • This method called whenever an it-block is applied to an object. The default implementation calls the function with this, and then returns this.

      Parameters

      • f: (arg0: this) => void

      Returns this

    • Create an Iri for a blank node. You may provide a label, or one will be automatically generated using Uuid. RDF writers may choose to omit the label during serialization if it is parseable as a Uuid.

      Two blank nodes with the same label are considered equal.

      Note: Technically, an IRI is not a blank node; they are two distinct types of resources. But we put a restriction on our IRI implementation such that all IRIs with ns _: are blank nodes.

      Parameters

      • Optionallabel: string

      Returns Iri

    • 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.

      Parameters

      Returns void

    • Parameters

      • iri: string
      • ...args: unknown[]

      Returns Iri

    • Parameters

      • ns: string
      • name: string
      • ...args: unknown[]

      Returns Iri

    • Make an Iri from a Uri. You should never use this constructor if the uri is intended to represent a prefixed IRI because a Uri will normalize its scheme. Becaues of this normalization, the following is true:

      // because `phIoT::elec`.toStr == "phiot:elec"
      Iri(`phIoT:elec`) != Iri("phIoT:elec")
      Iri(`phIoT:elec`) == Iri("phiot:elec")

      You have been warned.

      Parameters

      • uri: Uri
      • ...args: unknown[]

      Returns Iri
