pipeline-python.fiftyone_pipeline_core.fiftyone_pipeline_core.flowelement.FlowElement Class Reference

Detailed Description

A FlowElement is placed inside a Pipeline It receives Evidence via a FlowData object It uses this to optionally create ElementData on the FlowData Any errors in processing are caught in the FlowData's errors object.

@type flowdata: FlowData

Parameters

flowdata - a FlowData that has some Evidence set

@rtype: dict

Returns

: Returns a dictionary of evidence that has passed the filter

◆ filter_evidence_key()

def pipeline-python.fiftyone_pipeline_core.fiftyone_pipeline_core.flowelement.FlowElement.filter_evidence_key	(		self,
			key
	)

Filter FlowData.evidence using the flowElement's EvidenceKeyFilter with the property key of evidence of interest.

@type key: string

Parameters

key - the property key being sought within FlowData.evidence

@rtype: dict

Returns

: Returns a dictionary containing the property key and the evidence related to it as its value

◆ get_evidence_key_filter()

def pipeline-python.fiftyone_pipeline_core.fiftyone_pipeline_core.flowelement.FlowElement.get_evidence_key_filter

(

self

)

Filter FlowData evidence using the FlowElement's EvidenceKeyFilter.

@rtype: EvidenceKeyFilter

Returns

: Returns an EvidenceKeyFilter

◆ get_properties()

def pipeline-python.fiftyone_pipeline_core.fiftyone_pipeline_core.flowelement.FlowElement.get_properties

(

self

)

Get the FlowElement.properties of a FlowElement.

This is usually overridden by specific flowElements.

@rtype: DataPropertyDictionary

Returns

: Returns dictionary of the FlowElement's properties

◆ on_registration()

def pipeline-python.fiftyone_pipeline_core.fiftyone_pipeline_core.flowelement.FlowElement.on_registration	(		self,
			pipeline
	)

Function called when an element is added to the pipeline.

Used for example, for elements that depend on other elements in a pipeline

@type pipeline: Pipeline

Parameters

pipeline - Pipeline the element has been added to

◆ process()

def pipeline-python.fiftyone_pipeline_core.fiftyone_pipeline_core.flowelement.FlowElement.process	(		self,
			flowdata
	)

Function for getting the FlowElement's EvidenceKeyFilter Used by the filterEvidence method.

@type flowdata: FlowData

Parameters

flowdata - FlowData to be processed

@rtype: mixed

Returns

: Returns whatever the self.processInternal method is set to return

◆ process_internal()

def pipeline-python.fiftyone_pipeline_core.fiftyone_pipeline_core.flowelement.FlowElement.process_internal	(		self,
			flowdata
	)

The method behind FlowElement.Process - it is called by the process() function.

It is usually overridden by specific flowElements to do their core work.

@type flowdata: FlowData

Parameters

flowdata - FlowData to be processed

@rtype: bool

Returns

: Returns True
