Detailed Description

The Pipeline groups together FlowElements and is a factory for FlowData which serves as the evidence, results, and a means to access the Pipeline's processing capabilities.

A FlowData is linked to the Pipeline which created it, and cannot function without it.

Member Function Documentation

◆ createFlowData()

FlowData fiftyone.pipeline.core.flowelements.Pipeline.createFlowData

(

)

Create a new FlowData instance linked to this Pipeline.

The resulting FlowData's FlowData#process() method will cause the FlowData to be processed.

Returns: a new FlowData linked to this Pipeline

◆ getElement()

<T extends FlowElement> T fiftyone.pipeline.core.flowelements.Pipeline.getElement

(

Class< T >

type

)

Get the specified element from the pipeline.

If the pipeline contains multiple elements of the requested type, this method will return null.

Parameters: type - the type of the FlowElement to get; <T> - the type of the FlowElement to get

Returns: An instance of the specified FlowElement if the pipeline contains one. Null is returned if there is no such instance or there are multiple instances of that type.

◆ getElementAvailableProperties()

Map<String, Map<String, ElementPropertyMetaData> > fiftyone.pipeline.core.flowelements.Pipeline.getElementAvailableProperties

(

)

Get the map of available properties for an FlowElement#getElementDataKey().

The map returned contains the ElementPropertyMetaDatas keyed on the name field.

Returns: an immutable map of available properties

◆ getEvidenceKeyFilter()

EvidenceKeyFilter fiftyone.pipeline.core.flowelements.Pipeline.getEvidenceKeyFilter

(

)

Get the evidence keys used by all the FlowElements in the Pipeline.

Returns: merged list of evidence keys

◆ getFlowElements()

List<FlowElement> fiftyone.pipeline.core.flowelements.Pipeline.getFlowElements

(

)

Get list of the flow elements that are part of this pipeline.

Returns: an immutable list of the flow elements

◆ isClosed()

boolean fiftyone.pipeline.core.flowelements.Pipeline.isClosed

(

)

Indicates whether the Pipeline has been closed using the close() method, either explicitly or as a result of a 'try with resource'.

Returns: true if the Pipeline has been closed

◆ isConcurrent()

boolean fiftyone.pipeline.core.flowelements.Pipeline.isConcurrent

(

)

True if any of the FlowElements in this pipeline will create multiple threads and execute in parallel.

False otherwise.

Returns: true if any FlowElements are concurrent
