booleanlayer
layer: Layer | ArcGISSubLayer1 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.
parentDataSource
parentDataSource: DataSourceThe parent data source of this data source, mull means it's a root data source.
ready
ready: () => Promise<any>Type declaration
function(): Promise<any>Ready is resolved means the data source instance is ready for use.
Returns
Promise<any>selectRecordById
selectRecordById: (id: string, record?: DataRecord, forceCheck?: boolean) => voidType declaration
function(id: string, record?: DataRecord, forceCheck?: boolean): voidSelect a record by ID.
When select record by ID, we can pass in the record. So when the selected record is not loaded, we can add it in.
If forceCheck is true, will check whether the record match filters of the data source or not. Will select the record only if the check is passed.
Parameters
| Parameter | Type | Notes |
|---|---|---|
id | string | The ID to be selected. The selection will be cleared if the ID is null. |
record | DataRecord | |
force | boolean |
Returns
voidselectRecordsByIds
selectRecordsByIds: (ids: string[], records?: DataRecord[], forceCheck?: boolean) => voidType declaration
function(ids: string[], records?: DataRecord[], forceCheck?: boolean): voidSelect records by IDs.
When select records by IDs, we can pass in the records. So when the selected records are not loaded, we can add them in.
If forceCheck is true, will check whether these records match filters of the data source or not. Will select the records which check is passed.
Parameters
| Parameter | Type | Notes |
|---|---|---|
ids | string[] | The IDs to be selected. The selection will be cleared if the IDs are null. |
records | DataRecord[] | |
force | boolean |
Returns
voidsetCountStatus
setCountStatus: (status: DataSourceStatus) => voidType declaration
function(status: DataSourceStatus): voidUpdate data source count status.
Parameters
| Parameter | Type |
|---|---|
status | DataSourceStatus |
Returns
voidsetDataSourceJson
setDataSourceJson: (dsJson: IMDataSourceJson) => voidType declaration
function(dsJson: IMDataSourceJson): voidUpdate data source JSON in data source instance
Parameters
| Parameter | Type |
|---|---|
d | IMDataSourceJson |
Returns
voidsetListenSelection
setListenSelection: (listen: boolean) => voidType declaration
function(listen: boolean): voidWhether 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.
Parameters
| Parameter | Type |
|---|---|
listen | boolean |
Returns
voidsetRecords
setRecords: (records: DataRecord[]) => voidType declaration
function(records: DataRecord[]): voidUpdate the records in the data source object only, does not update the source data.
Parameters
| Parameter | Type |
|---|---|
records | DataRecord[] |
Returns
voidsetSourceRecords
setSourceRecords: (records: DataRecord[]) => voidType declaration
function(records: DataRecord[]): voidWhen 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.
Parameters
| Parameter | Type |
|---|---|
records | DataRecord[] |
Returns
voidsetStatus
setStatus: (status: DataSourceStatus) => voidType declaration
function(status: DataSourceStatus): voidUpdate data source status.
Parameters
| Parameter | Type |
|---|---|
status | DataSourceStatus |
Returns
voidupdateSelectionInfo
updateSelectionInfo: (ids: string[], triggerDataSource: DataSource, forceCheck?: boolean) => voidType declaration
function(ids: string[], triggerDataSource: DataSource, forceCheck?: boolean): voidUpdate selected record IDs 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 curren 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.
Parameters
| Parameter | Type |
|---|---|
ids | string[] |
trigger | DataSource |
force | boolean |
