[n: number]: GraphSubject

Convenience for collections of identified Subjects, such as found in a MeldUpdate. Extends Array and serialisable to JSON-LD as such.

Index

Properties

Array

Array: ArrayConstructor

graph

graph: ReadonlyMap<Iri, GraphSubject>

Subjects in the collection indexed by @id. In addition, if a Subject in the graph references another Subject in the same graph, the reference is realised as a Javascript reference, so it is possible to traverse the graph from some known root object. This means that the graph cannot necessarily by serialised to JSON as it may not be acyclic.

length

length: number

Gets or sets the length of the array. This is a number one higher than the highest index in the array.

Methods

[Symbol.iterator]

[Symbol.unscopables]

  • [Symbol.unscopables](): { copyWithin: boolean; entries: boolean; fill: boolean; find: boolean; findIndex: boolean; keys: boolean; values: boolean }

copyWithin

  • copyWithin(target: number, start: number, end?: undefined | number): this
  • Returns the this object after copying a section of the array identified by start and end to the same array starting at position target

    Parameters

    • target: number

      If target is negative, it is treated as length+target where length is the length of the array.

    • start: number

      If start is negative, it is treated as length+start. If end is negative, it is treated as length+end.

    • Optional end: undefined | number

      If not specified, length of the this object is used as its default value.

entries

every

  • Determines whether all the members of an array satisfy the specified test.

    Type parameters

    Parameters

    • predicate: (value: GraphSubject, index: number, array: GraphSubject[]) => value is S

      A function that accepts up to three arguments. The every method calls the predicate function for each element in the array until the predicate returns a value which is coercible to the Boolean value false, or until the end of the array.

    • Optional thisArg: any

      An object to which the this keyword can refer in the predicate function. If thisArg is omitted, undefined is used as the this value.

    Returns this is S[]

  • Determines whether all the members of an array satisfy the specified test.

    Parameters

    • predicate: (value: GraphSubject, index: number, array: GraphSubject[]) => unknown

      A function that accepts up to three arguments. The every method calls the predicate function for each element in the array until the predicate returns a value which is coercible to the Boolean value false, or until the end of the array.

    • Optional thisArg: any

      An object to which the this keyword can refer in the predicate function. If thisArg is omitted, undefined is used as the this value.

    Returns boolean

fill

  • fill(value: GraphSubject, start?: undefined | number, end?: undefined | number): this
  • Returns the this object after filling the section identified by start and end with value

    Parameters

    • value: GraphSubject

      value to fill array section with

    Type parameters

    Parameters

    Returns S[]

  • Returns the elements of an array that meet the condition specified in a callback function.

    Parameters

    • predicate: (value: GraphSubject, index: number, array: GraphSubject[]) => unknown

      A function that accepts up to three arguments. The filter method calls the predicate function one time for each element in the array.

    Parameters

    • predicate: (this: void, value: GraphSubject, index: number, obj: GraphSubject[]) => value is S

      find calls predicate once for each element of the array, in ascending order, until it finds one where predicate returns true. If such an element is found, find immediately returns that element value. Otherwise, find returns undefined.

  • Returns the index of the first element in the array where predicate is true, and -1 otherwise.

    Parameters

    • predicate: (value: GraphSubject, index: number, obj: GraphSubject[]) => unknown

      find calls predicate once for each element of the array, in ascending order, until it finds one where predicate returns true. If such an element is found, findIndex immediately returns that element index. Otherwise, findIndex returns -1.

    • Optional thisArg: any

      If provided, it will be used as the this value for each invocation of predicate. If it is not provided, undefined is used instead.
