◆ getMetaDataForProperty()

ElementPropertyMetaData fiftyone.pipeline.core.flowelements.PipelineInternal.getMetaDataForProperty

(

String

propertyName

)

throws PipelineDataException

Get the meta data for the specified property name.

If there are no properties with that name or multiple properties on different elements then an exception will be thrown.

Parameters: propertyName - the property name to find the meta data for

Returns: the meta data associated with the specified property name

Exceptions: PipelineDataException - if the property name is associated with zero or multiple elements.

◆ process()

void fiftyone.pipeline.core.flowelements.PipelineInternal.process

(

FlowData

data

)
