Coveo component PipelineContext

A PipelineContext is used to add contextual information about the environment inside which the query is executed.

It allows to pass arbitrary key values pairs ( think JSON ), which can then be leveraged by the Query Pipeline, or by Reveal.

This can be any arbitrary information that you can use to contextualize the query and help Coveo improve relevance by returning results tailored to a specific context.

This component is meant to be configured using a script tag, with a JSON content.

<script class='CoveoPipelineContext' type='text/context'>
  {
     "foo" : "bar"
  }
</script>

You can also simply use JavaScript code to pass context values, using the QueryBuilder.addContextValue method.

This mean you do not necessarily need to use this component to pass context.

Coveo.$$(root).on('buildingQuery', function(args) {
    args.queryBuilder.addContextValue('foo', 'bar');
})

Using this component as opposed to JavaScript code means you will be able to leverage the interface editor.

Regardless of if you use this component or JavaScript to add context, both will add the needed data in the Query.Context parameter.

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

getContextKeys

  • getContextKeys(): string[]

getContextValue

  • getContextValue(key: string): string

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

  • Create a new Component. Resolve all IComponentBindings if not provided.
    Create a new Logger for this component. Attach the component to the SearchInterface.

    Parameters

    • element: HTMLElement

      The HTMLElement on which to create the component. Used to bind data on the element.

    • type: string

      The unique identifier for this component. See : IComponentDefinition.ID. Used to generate the unique Coveo CSS class associated with every component.

    • Default value bindings: IComponentBindings = {}

      The environment for every component. Optional, but omitting to provide one will impact performance.

    Returns PipelineContext
