layer
layer: Layer | ArcGISSubLayer
1 How to use ArcGIS Maps SDK for JavaScript layer
1.1 a data source may have a layer, the layer is the source of the data source ( isDataInDataSourceInstance
should be false) and is used to save source data and communicate with Maps SDK for JavaScript (get popupTemplate, symbol and so on), if want to query features, should use data source instance, not the layer.
1.2 main data source and all other data views/local data source share the same layer.
1.3 selection view create a new layer when do query, but doesn't save the layer.
1.4 if widget needs an ArcGIS Maps SDK for JavaScript layer, call dataSource.createJSAPILayerByDataSource()
to create a new layer, do not use the layer in data source instance directly, to listen data source changes and apply the changes to the new layer, see 2.2.
2 How to listen data source changes via DataSourceComponent
2.1 if widget loads records, use onDataSourceInfoChange
to listen selected records change, query params change and loaded records change.
2.2 if widget doesn't load records (use a Maps SDK for JavaScript widget and needs an ArcGIS Maps SDK for JavaScript layer), use onQueryRequired
to listen query params change, use onSelectionChange
to listen selected records change.
3 Relation between output data source and origin data source
3.1 if schema is not changed (e.g. query output) and only has one origin data source, will use origin data source's layerDefinition
, popupInfo
and Maps SDK for JavaScript layer
.
3.2 if schema is changed (e.g. chart output), need widget to set layerDefinition
, popupInfo
and Maps SDK for JavaScript layer
to data source instance.
localId
localId: string
The local ID of the data source.
order
order: number
Order in the parent data source.
parentDataSource

The parent data source of this data source, mull means it's a root data source.
ready
ready: () => Promise<any>

Please note that can not make sure all child data sources are created if a set data source is ready.
To make sure all child data sources are created, please use childDataSourcesReady
.
Type declaration
function(): Promise<any>
Returns
Promise<any>

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 curren data source is main data source (we suppose that main data source contains all records, no need to check).
