constructor

new RouteLayerQueryIdentifyProvider(): RouteLayerQueryIdentifyProvider
Returns RouteLayerQueryIdentifyProvider
Inherited from IdentifyProviderBase.constructor

Methods

`Protected`_applyTolerance

_applyTolerance(geometry, options?): Promise<GeometryUnion>
Adds a tolerance to input geometries if configured in the options.
Parameters
- geometry: GeometryUnion
  The geometry to apply a tolerance to.
- Optionaloptions: IdentifyOptions
  The identify options object.
Returns Promise<GeometryUnion>
Inherited from IdentifyProviderBase._applyTolerance

`Protected`_count

_count(source, geometry, options): Promise<CountResult>
Invoked to perform the actual work for count. Derived classes should override this method rather than count().
Parameters
- source: FeatureSource
  The source to identify.
- geometry: GeometryUnion
  The geometry to match against.
- options: IdentifyOptions
  Options that affect the identify operation.
Returns Promise<CountResult>
Overrides IdentifyProviderBase._count

`Protected`_identify

_identify(source, geometry, options): AsyncIterable<Feature, any, any>
Invoked to perform the actual work for identify on a single source. Derived classes should override this method rather than identify().
Parameters
- source: FeatureSource
  The source to identify.
- geometry: GeometryUnion
  The geometry to match against.
- options: IdentifyOptions
  Options that affect the identify operation.
Returns AsyncIterable<Feature, any, any>
Overrides IdentifyProviderBase._identify

`Protected`_identifyMany

_identifyMany(sources, geometry, options, geometryType?): AsyncIterable<Feature, any, any>
Invoked to perform the work for identify. Default implementation calls _identify for each source. Derived classes can override this method to implement special handling for multiple sources.
Parameters
- sources: FeatureSource[]
  The sources to identify.
- geometry: GeometryUnion
  The geometry to match against.
- options: IdentifyOptions
  Options that affect the identify operation.
- OptionalgeometryType: string
  The geometry type before a tolerance buffer is applied.
Returns AsyncIterable<Feature, any, any>
Inherited from IdentifyProviderBase._identifyMany

count

count(source, geometry, options?): Promise<CountResult>
Counts features in a given source that intersect the given geometry.
Parameters
- source: FeatureSource
  The source to identify.
- geometry: GeometryUnion
  The geometry to match against.
- Optionaloptions: IdentifyOptions
  Options that affect the identify operation.
Returns Promise<CountResult>
An iterable of tasks/CountResult!CountResults containing count results. If canceled, the provider may reject the returned promise with an instance of support/Cancellable!Cancellation, though it may still fulfill with count results instead.

Inherited from IdentifyProviderBase.count

identify

identify(source, geometry, options?): AsyncIterable<Feature, any, any>
Identifies features in a given source that intersect the given geometry.
Parameters
- source: FeatureSource | FeatureSource[]
  The source to identify.
- geometry: GeometryUnion
  The geometry to match against.
- Optionaloptions: IdentifyOptions
  Options that affect the identify operation.
Returns AsyncIterable<Feature, any, any>
An iterable of data/Feature!Features containing identify results. If canceled, the provider may reject the returned promise with an instance of support/Cancellable!Cancellation, though it may still fulfill with results instead.

isSupported

isSupported(source, geometry, options?): boolean
Determines whether this provider can handle identify operations for the given feature source.
Parameters
- source: FeatureSource
  The feature source.
- geometry: GeometryUnion
- Optionaloptions: IdentifyOptions
Returns boolean
Overrides IdentifyProviderBase.isSupported
