Detailed Description

Abstract base class for AspectData which overrides the AspectData#get(String) method to add null checks and uses the MissingPropertyService to determine the reason for a value not being present.

For example, if the user has excluded the property at the configuration stage.

Member Function Documentation

◆ addEngine()

void fiftyone.pipeline.engines.data.AspectDataBase.addEngine

(

AspectEngine

engine

)

Add an engine to the list of engines which have generated the data within this instance.

Parameters: engine - engine adding data

◆ addProcessCallable()

void fiftyone.pipeline.engines.data.AspectDataBase.addProcessCallable

(

ProcessCallable

runnable

)

Add a callable which will run a AspectEngine#process(FlowData) method to populate this instance.

The property accessors will only complete once all such tasks have completed.

Parameters: runnable - processing runnable

◆ asKeyMap()

Map<String, Object> fiftyone.pipeline.engines.data.AspectDataBase.asKeyMap

(

)

Get the data contained in this instance as a read only Map.

Returns: the data

Implements fiftyone.pipeline.core.data.Data.

◆ get()

Object fiftyone.pipeline.engines.data.AspectDataBase.get

(

String

propertyName

)

throws PropertyMissingException

Gets the value stored using the specified key with full checks against the MissingPropertyService.

Parameters: propertyName - to get the value for

Returns: value of the property

Exceptions: PropertyMissingException - the property was not found

Implements fiftyone.pipeline.core.data.Data.

◆ getEngines()

List<AspectEngine> fiftyone.pipeline.engines.data.AspectDataBase.getEngines

(

)

Get the engines that generated the data withing this data instance.

Returns: engines which generated the data

Implements fiftyone.pipeline.engines.data.AspectData.

◆ getProcessFuture()

Future<?> fiftyone.pipeline.engines.data.AspectDataBase.getProcessFuture

(

)

If the engine is configured for lazy loading, this property returns a Future that will complete once the engine has finished processing.

Otherwise, it will be null.

Returns: lazy loading future or null
