QueriableDataSource

Interface

QueriableDataSource extends DataSource and add query capability. A queriable data source must have an URL to execute the query.

The current default query implementation supports pagination. It allows multiple widgets to apply queries on the same data source, all of which are merged by using the AND logic operator.

When execute a query, in addition to the passed in query parameters, all configured queries and all other widgets applied queries are merged by using the AND logic operator.

When a query is executed against a data view, the query from its main data source is used as well.

setListenSelection

inheritedinherited

Interface Property

setListenSelection: (listen: boolean) => void

Whether listen selected records from other data sources which are derived from the same main data source. If true, will update selected record IDs of current data source info when selecting records via other derived data sources. Will also update selected record IDs when selecting records via current data source itself. If false, won't change selected record IDs when selecting records via other derived data sources. Will update selected record IDs only when selecting records via current data source itself.

Main data source and its data views will listen selected records by default, local data source does not listen selected records by default.

Type declaration

function(listen: boolean): void

Parameters

Parameter	Type
`listen`	boolean

Returns

void

Inherited from DataSource.setListenSelection

Update the records in the data source object only, does not update the source data.

Type declaration

function(records: DataRecord[]): void

Parameters

Parameter	Type
`records`	DataRecord[]

Returns

void

Inherited from DataSource.setRecords

setSourceRecords

inheritedinherited

Interface Property

setSourceRecords: (records: DataRecord[]) => void

When current data source is created from an array of records, will save it in sourceRecords . These two methods are used to update or get the source data.

Type declaration

function(records: DataRecord[]): void

Parameters

Parameter	Type
`records`	DataRecord[]

Returns

void

Inherited from DataSource.setSourceRecords

setStatus

optionalinheritedinherited

Interface Property

setStatus: (status: DataSourceStatus) => void

Update data source status.

Type declaration

function(status: DataSourceStatus): void

Parameters

Parameter	Type
`status`	DataSourceStatus

Returns

updateQueryParams

Interface Property

updateQueryParams: (query: QueryParams, widgetId: string) => void

Update the data source query without executing the actual query.

Type declaration

function(query: QueryParams, widgetId: string): void

Parameters

Parameter	Type
`query`	QueryParams
`widgetId`	string

Returns

updateSelectionInfo

inheritedinherited

Interface Property

updateSelectionInfo: (options: SelectOptions, triggerDataSource: DataSource, forceCheck?: boolean) => void

Update selected records in data source info if the current data source listens selection change (see setListenSelection ) or the current data source is the trigger data source (that is to say, select via it).

Before update info, will check whether these selected records match filters of the current data source firstly, and then only set the matched selected records to info. Will skip the check in some cases to improve performance if the forceCheck is not passed in or is false. For example, if the current data source is main data source (we suppose that main data source contains all records, no need to check). But if the forceCheck is true, won't skip the check.

Type declaration

function(options: SelectOptions, triggerDataSource: DataSource, forceCheck?: boolean): void

Parameters

Parameter	Type
`options`	SelectOptions
`triggerDataSource`	DataSource
`forceCheck`	boolean

Returns
