    Methods

    • List of nodes added, or empyt list if no nodes added.

      Returns List<Elem>

    • List of nodes added, or empyt list if no nodes added.

      Parameters

      Returns void

    • Name of the changed attribute, or null if no attribute was changed.

      Returns string

    • Name of the changed attribute, or null if no attribute was changed.

      Parameters

      • it: string

      Returns void

    • Namespace of the changed attribute, or null if no attribute was changed.

      Returns string

    • Namespace of the changed attribute, or null if no attribute was changed.

      Parameters

      • it: string

      Returns void

    • 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

    • 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

    • 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

    • Next sibling of the added or removed nodes, or null if no nodes added or removed.

      Returns Elem

    • Next sibling of the added or removed nodes, or null if no nodes added or removed.

      Parameters

      Returns void

    • Old value, depending on type:

      • For "attrs", it is the value of the changed attribute before the change
      • For "charData", it is the data of the changed node before the change
      • For "childList", it is null

      Returns string

    • Old value, depending on type:

      • For "attrs", it is the value of the changed attribute before the change
      • For "charData", it is the data of the changed node before the change
      • For "childList", it is null

      Parameters

      • it: string

      Returns void

    • Previous sibling of the added or removed nodes, or null if not nodes added or removed.

      Returns Elem

    • Previous sibling of the added or removed nodes, or null if not nodes added or removed.

      Parameters

      Returns void

    • List of nodes removed, or empty list if no nodes removed.

      Returns List<Elem>

    • List of nodes removed, or empty list if no nodes removed.

      Parameters

      Returns void

    • Target node that mutation affected, depending on the type:

      • For "attrs", it is the element whose attribute changed
      • For "charData", it is the CharacterData node
      • For "childList", it is the node whose children changed

      Returns Elem

    • Target node that mutation affected, depending on the type:

      • For "attrs", it is the element whose attribute changed
      • For "charData", it is the CharacterData node
      • For "childList", it is the node whose children changed

      Parameters

      Returns void

    • 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

    • Mutation type:

      • "attrs" if the mutation was an attribute mutation
      • "charData" if it was a mutation to a CharacterData node
      • "childList" if it was a mutation to the tree of nodes

      Returns string

    • Mutation type:

      • "attrs" if the mutation was an attribute mutation
      • "charData" if it was a mutation to a CharacterData node
      • "childList" if it was a mutation to the tree of nodes

      Parameters

      • it: string

      Returns void

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

      Returns Type

    • 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

    • 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
