Non-Dataflow Workers

A non-dataflow (a.k.a. control flow) worker has no input or output ports.

Also see the dataflow workers:

Note

There is no fundamental difference between dataflow and non-dataflow workers; they can be mixed and matched as needed.

ActionWorker

Run an Action or Func callback, optionally creating child workers.

ActionWorkerBase

Run an Action or Func callback, optionally creating child workers. Must be inherited.

AdbExecuteNonQueryWorker

Execute a query on an SQL database (e.g. INSERT, UPDATE, DELETE and DML statements) without returning any result set. Can also generate provider-specific TRUNCATE, DROP, DELETE, IF EXISTS table statements. RecordsAffected is returned.

AdbExecuteScalarWorker

Execute a query on an SQL database and return a single result value.

AdbTableNonQueryWorker

Execute a query on a table-like object in an SQL database: DELETE all rows (with RecordsAffected), IF EXISTS, DROP, or TRUNCATE.

AdbTransactionActionWorker

Creates an AdbKeepOpenConnection and a local AdbTransaction, runs a user supplied callback inside the transaction, and commits/rolls back and disposes the transaction and connection.

CopyFileWorker

Copy a file.

CreateFileWorker

Create a file.

DeleteFileWorker

Delete a file.

ExecuteProcessWorker

Launch an external process, e.g. an executable, a batch script, or a document.

FileExistsWorker

Check if a file exists.

ForEachActionWorker

Execute an Action or Func callback once (optionally creating child workers) for each item in an enumerable.

MoveFileWorker

Move a file.

UsingActionWorker

Mimics the using statement in C#/VB to create an arbitrary disposable object, run a callback with the disposable object, and automatically dispose the object.

WhileActionWorker

Execute an Action or Func callback (optionally creating child workers) for each iteration in a while-loop.

Worker

Bare-bones worker with only the intrinsic functionality inherited from WorkerBase<TDerived> and WorkerBase, such as start constraints and grouping children.

WorkerBase and WorkerBase<TDerived>

WorkerBase is a base class that all other workers inherit from indirectly, via WorkerBase<TDerived>.

Specify WorkerBase when referring to workers without knowing the final derived worker type. It has many useful members, such as the worker Name, Parent, etc.

WorkerBase<TDerived> is a base class that all other workers inherit from directly or indirectly. It contains members that use the type of the final derived worker (TDerived).
