Coveo component Aggregate

Coveo Aggregate Component (CoveoAggregate)

The Aggregate component allows to display the result on an aggregate operation on the index.

It hooks itself to the query to add a new IGroupByRequest, then displays the result.

Index

Component Options

field

Specifies the field on which to do the aggregate operation. This parameter is mandatory.

Markup configuration example(s) :
data-field='@foo'

format

format: string

Specifies how to format the value.

The available formats are defined in the Globalize library (see Globalize.

The most commonly used formats are:

  • c0 - Formats the value as a currency.
  • n0 - Formats the value as an integer.
  • n2 - Formats the value as a floating point with 2 decimal digits.

Default value is c0.

Markup configuration example(s) :
data-format='foo'

operation

operation: string

Specifies the aggregate operation to perform.

The possible values are:

  • sum - Computes the sum of the computed field values.
  • average - Computes the average of the computed field values.
  • minimum - Finds the minimum value of the computed field values.
  • maximum - Finds the maximum value of the computed field values.

Default value is sum.

Markup configuration example(s) :
data-operation='foo'

Methods

debugInfo

  • debugInfo(): any

disable

  • disable(): void
  • Disable the component. Normally this means that the component will not execute handlers for the framework events (query events, for example). Component are enabled by default on creation.

    Returns void

enable

  • enable(): void
  • Enable the component. Normally this means that the component will execute handlers for the framework events (query events, for example). Components are enabled by default on creation.

    Returns void

getBindings

Static get

  • get(element: HTMLElement, componentClass?: any, noThrow?: boolean): BaseComponent
  • Get the bound component to the given HTMLElement. Throws an assert if the HTMLElement has no component bound, unless using the noThrow argument.
    If there is multiple component bound to the current HTMLElement, you must specify the component class.

    Parameters

    • element: HTMLElement

      HTMLElement for which to get the bound component.

    • Optional componentClass: any

      Optional component class. If the HTMLElement has multiple components bound, you must specify which one you are targeting.

    • Optional noThrow: boolean

      Boolean option to tell the method to not throw on error.

    Returns BaseComponent

Properties

bind

Allows the component to bind events and execute them only when it is enabled.

type

{Coveo.ComponentEvents}

componentOptionsModel

componentOptionsModel: ComponentOptionsModel

Contains the state of options for differents component. Mainly used by ResultLink.

componentStateModel

componentStateModel: ComponentStateModel

Contains the state of different component (enabled vs disabled). Allows to get/set values. Trigger component state event when modified. Each component can listen to those events.

disabled

disabled: boolean

A disabled component will not participate in the query, or listen to ComponentEvents.

type

{boolean}

logger

logger: Logger

Allows component to log in the dev console.

queryController

queryController: QueryController

Contains the singleton that allows to trigger queries.

queryStateModel

queryStateModel: QueryStateModel

Contains the state of the query. Allows to get/set values. Trigger query state event when modified. Each component can listen to those events.

root

root: HTMLElement

A reference to the root HTMLElement (the SearchInterface).

searchInterface

searchInterface: SearchInterface

A reference to the root of every component, the SearchInterface.

usageAnalytics

usageAnalytics: IAnalyticsClient

A reference to the Analytics.client.

Static ID

ID: string

The static ID that each component need to be identified.
For example, SearchButton -> static ID : SearchButton -> className : CoveoSearchButton

Constructors

constructor

  • Creates a new Aggregate component.

    Parameters

    • element: HTMLElement

      The HTMLElement on which to instantiate the component.

    • Optional options: IAggregateOptions

      The options for the Aggregate component.

    • Optional bindings: IComponentBindings

      The bindings that the component requires to function normally. If not set, these will be automatically resolved (with a slower execution time).

    Returns Aggregate
