Declaration
public CustomSource()

CustomSource(Func<Int32, TOutput>, Predicate<Int32>)

Declaration
public CustomSource(Func<int, TOutput> readFunc, Predicate<int> readingCompleted)
Parameters
Type Name Description
System.Func<System.Int32, TOutput> readFunc

Sets the ReadFunc
System.Predicate<System.Int32> readingCompleted

Sets the ReadingCompleted

Properties

ReadFunc

The function that returns a data row as output. An integer value with the current progress count is the input of the function.

Declaration
public Func<int, TOutput> ReadFunc { get; set; }
Property Value
Type Description
System.Func<System.Int32, TOutput>

ReadingCompleted

This predicate returns true when all rows for the flow are successfully returned from the ReadFunc. An integer value with the current progress count is the input of the predicate.

Declaration
public Predicate<int> ReadingCompleted { get; set; }
Property Value
Type Description
System.Predicate<System.Int32>

TaskName

A name to identify the task or component. Every component or task comes with a default name that can be overwritten.

Declaration
public override string TaskName { get; set; }
