51Degrees Pipeline .NET  4.4

51Degrees Pipeline for .NET

FiftyOne.Pipeline.Core.FlowElements.FlowElementBase< T, TMeta > Class Template Reference abstract

Detailed Description

Abstract base class for Flow Elements.

See the Specification

It is not a requirement for all FlowElements to extend FlowElementBase<T, TMeta> but it is recommended. They must implement IFlowElement though.

Template Parameters
T - The type of element data that the flow element will write to IFlowData.
TMeta - The type of meta data that the flow element will supply about the properties it populates.
Type Constraints
T :IElementData 
TMeta :IElementPropertyMetaData

◆ Dispose() [1/2]

virtual void FiftyOne.Pipeline.Core.FlowElements.FlowElementBase< T, TMeta >.Dispose ( bool   disposing )
protected virtual

Dispose of any resources.

Parameters
disposing - True if Dispose is being called 'correctly' from the Dispose method. False if Dispose is being called by the finalizer.

◆ ManagedResourcesCleanup()

abstract void FiftyOne.Pipeline.Core.FlowElements.FlowElementBase< T, TMeta >.ManagedResourcesCleanup ( )
protected pure virtual

Cleanup any managed resources that the element is using

Implemented in FiftyOne.Pipeline.Engines.FiftyOne.FlowElements.ShareUsageBase, FiftyOne.Pipeline.Engines.FlowElements.AspectEngineBase< T, TMeta >, FiftyOne.Pipeline.JavaScriptBuilder.FlowElement.JavaScriptBuilderElement, FiftyOne.Pipeline.JsonBuilder.FlowElement.JsonBuilderElement, FiftyOne.Pipeline.Core.FlowElements.ParallelElements, FiftyOne.Pipeline.Engines.FlowElements.OnPremiseAspectEngineBase< T, TMeta >, Examples.ClientSideEvidence.Shared.SimpleClientSideElement, FiftyOne.Pipeline.Engines.FiftyOne.FlowElements.SetHeadersElement, Examples.CustomFlowElement.FlowElements.SimpleFlowElement, FiftyOne.Pipeline.Math.MathElement, FiftyOne.Pipeline.IpSplitter.IpSplitterElement, and FiftyOne.Pipeline.Engines.FiftyOne.FlowElements.SequenceElement.

◆ Process()

virtual void FiftyOne.Pipeline.Core.FlowElements.FlowElementBase< T, TMeta >.Process ( IFlowData   data )
virtual

Process the given IFlowData with this FlowElement.

Parameters
data - The IFlowData instance that provides input evidence and carries the output data to the user.
Exceptions
ArgumentNullException - Thrown if the supplied data parameter is null.

◆ UnmanagedResourcesCleanup()

abstract void FiftyOne.Pipeline.Core.FlowElements.FlowElementBase< T, TMeta >.UnmanagedResourcesCleanup ( )
protected pure virtual

Cleanup any unmanaged resources that the element is using

Implemented in FiftyOne.Pipeline.JavaScriptBuilder.FlowElement.JavaScriptBuilderElement, FiftyOne.Pipeline.Engines.FiftyOne.FlowElements.ShareUsageBase, FiftyOne.Pipeline.JsonBuilder.FlowElement.JsonBuilderElement, FiftyOne.Pipeline.Core.FlowElements.ParallelElements, Examples.ClientSideEvidence.Shared.SimpleClientSideElement, FiftyOne.Pipeline.Engines.FiftyOne.FlowElements.SequenceElement, FiftyOne.Pipeline.Engines.FiftyOne.FlowElements.SetHeadersElement, Examples.CustomFlowElement.FlowElements.SimpleFlowElement, FiftyOne.Pipeline.Math.MathElement, and FiftyOne.Pipeline.IpSplitter.IpSplitterElement.

Property Documentation

◆ Asynchronous

virtual bool FiftyOne.Pipeline.Core.FlowElements.FlowElementBase< T, TMeta >.Asynchronous
get

True if the element can be run totally asynchronously, false otherwise.

This should only return true if the FlowElement does not modify the IFlowData or it's values are lazily loaded. Otherwise the process method may return before the element has completed processing.
