constructor

• new MathModifier(options: Partial<MathModifierOptions>): MathModifier

  Parameters

  • options: Partial<MathModifierOptions>

  Returns MathModifier

options

Statictypes

benchmark

• benchmark(dataTable: DataTable, options?: BenchmarkOptions): number[]

  Runs a timed execution of the modifier on the given datatable. Can be configured to run multiple times.

  Parameters

  • dataTable: DataTable

    The datatable to execute

  • Optionaloptions: BenchmarkOptions

    Options. Currently supports iterations for number of iterations.

  Returns number[]

  An array of times in milliseconds

emit

• emit<E extends DataModifierEvent>(e?: E): void

  Emits an event on the modifier to all registered callbacks of this event.

  Type Parameters

  • E extends DataModifierEvent

  Parameters

  • Optionale: E

    Event object containing additonal event information.

  Returns void

modify

• modify(table: DataTable, eventDetail?: DataEventDetail): Promise<DataTable>

  Modifies the given table and sets its modified property as a reference to the modified table. If modified property does not exist on the original table, it's always created.

  Parameters

  • table: DataTable

    Table to modify.

  • OptionaleventDetail: DataEventDetail

    Custom information for pending events.

  Returns Promise<DataTable>

  Table with modified property as a reference.

modifyTable

• modifyTable(table: DataTable, eventDetail?: DataEventDetail): DataTable

  Creates a modified copy of the given table and sets its modified property as a reference to the modified table. If modified property does not exist, the original table is changed.

  Parameters

  • table: DataTable

    Table to modify.

  • OptionaleventDetail: DataEventDetail

    Custom information for pending events.

  Returns DataTable

  Table with modified property as a reference or modified table, if modified property of the original table is undefined.
