Func< IPipeline, FlowElementBase< T, TMeta >, T >   aspectDataFactory,
string   tempDataFilePath

Member Function Documentation

◆ GetDataFileMetaData()

IAspectEngineDataFile FiftyOne.Pipeline.Engines.FlowElements.OnPremiseAspectEngineBase< T, TMeta >.GetDataFileMetaData ( string   dataFileIdentifier = null )

Get the details of a specific data file used by this engine.

Parameters
dataFileIdentifier - The identifier of the data file to get meta data for. This parameter is ignored if the engine only has one data file.
Returns
The meta data associated with the specified data file. Returns null if the engine has no associated data files.

Implements FiftyOne.Pipeline.Engines.FlowElements.IOnPremiseAspectEngine.

◆ RefreshData() [1/2]

abstract void FiftyOne.Pipeline.Engines.FlowElements.OnPremiseAspectEngineBase< T, TMeta >.RefreshData ( string   dataFileIdentifier )
pure virtual

Causes the engine to reload data from the file at IAspectEngineDataFile.DataFilePath for the data file matching the given identifier.

Implementors should consider thread-safety to ensure that parallel calls to 'Process' will resolve as normal.

Parameters
dataFileIdentifier - The identifier of the data file to update. Must match the value in IAspectEngineDataFile.Identifier. If the engine only has a single data file, this parameter is ignored. If null is passed then all data files should be refreshed.

Implements FiftyOne.Pipeline.Engines.FlowElements.IOnPremiseAspectEngine.

Implemented in Examples.OnPremiseEngine.FlowElements.SimpleOnPremiseEngine.

◆ RefreshData() [2/2]

abstract void FiftyOne.Pipeline.Engines.FlowElements.OnPremiseAspectEngineBase< T, TMeta >.RefreshData ( string   dataFileIdentifier,
Stream   data  
)
pure virtual

Causes the engine to reload data from the supplied Stream for the file matching the given identifier.

Implementors should consider thread-safety to ensure that parallel calls to 'Process' will resolve as normal.

Parameters
dataFileIdentifier - The identifier of the data file to update. Must match the value in IAspectEngineDataFile.Identifier. If the engine only has a single data file, this parameter is ignored.
data - A Stream containing the data to use when refreshing.

Implements FiftyOne.Pipeline.Engines.FlowElements.IOnPremiseAspectEngine.

Implemented in Examples.OnPremiseEngine.FlowElements.SimpleOnPremiseEngine.
