Inherited Members
Namespace: ETLBox.DataFlow
Assembly: ETLBox.dll
Syntax
    public static class NetworkHelper
Remarks

The caller selects the node. A replacement must be a real DataFlowComponent.

Methods

GetDestinations(IDataFlowComponent)

Destinations in the main flow. Auto-generated void destinations and error destinations are excluded.

Declaration
    public static IReadOnlyList<IDataFlowDestination> GetDestinations(IDataFlowComponent startNode)
Parameters
TypeNameDescription
IDataFlowComponentstartNode
Returns
TypeDescription
IReadOnlyList<IDataFlowDestination>

GetErrorDestinations(IDataFlowComponent)

Destinations linked through LinkErrorTo(IDataFlowDestination<ETLBoxError>).

Declaration
    public static IReadOnlyList<IDataFlowDestination<ETLBoxError>> GetErrorDestinations(IDataFlowComponent startNode)
Parameters
TypeNameDescription
IDataFlowComponentstartNode
Returns
TypeDescription
IReadOnlyList<IDataFlowDestination<ETLBoxError>>

GetSources(IDataFlowComponent)

Executable sources in the network. ErrorSource is excluded.

Declaration
    public static IReadOnlyList<IDataFlowExecutableSource> GetSources(IDataFlowComponent startNode)
Parameters
TypeNameDescription
IDataFlowComponentstartNode
Returns
TypeDescription
IReadOnlyList<IDataFlowExecutableSource>

ReplaceDestination<TReplacement>(IDataFlowComponent, Func<IDataFlowDestination, bool>, TReplacement)

Replaces the single main-flow destination for which match returns true.

Declaration
    public static TReplacement ReplaceDestination<TReplacement>(IDataFlowComponent startNode, Func<IDataFlowDestination, bool> match, TReplacement replacement) where TReplacement : DataFlowComponent, IDataFlowDestination
Parameters

ReplaceErrorDestination<TReplacement>(IDataFlowComponent, Func<IDataFlowDestination<ETLBoxError>, bool>, TReplacement)

Replaces the single error destination for which match returns true.

Declaration
    public static TReplacement ReplaceErrorDestination<TReplacement>(IDataFlowComponent startNode, Func<IDataFlowDestination<ETLBoxError>, bool> match, TReplacement replacement) where TReplacement : DataFlowComponent, IDataFlowDestination<ETLBoxError>

ReplaceErrorDestination<TReplacement>(IDataFlowComponent, Func<IReadOnlyList<IDataFlowDestination<ETLBoxError>>, IDataFlowDestination<ETLBoxError>>, TReplacement)

Replaces one error destination. The selector must return one of the offered error destinations.

Declaration
    public static TReplacement ReplaceErrorDestination<TReplacement>(IDataFlowComponent startNode, Func<IReadOnlyList<IDataFlowDestination<ETLBoxError>>, IDataFlowDestination<ETLBoxError>> select, TReplacement replacement) where TReplacement : DataFlowComponent, IDataFlowDestination<ETLBoxError>
Parameters

TReplacementreplacement
Returns
TypeDescription
TReplacement
Type Parameters
NameDescription
TReplacement

ReplaceSource<TReplacement>(IDataFlowComponent, Func<IDataFlowExecutableSource, bool>, TReplacement)

Replaces the single source for which match returns true.
