Control

Unit	Description
If (Formerly Branch)	Executes the True branch if the provided input is true, otherwise executes the False branch.
Break	Immediately exits the current loop.
Cache	Flow node reads its input value whenever a value from any source is entered and outputs it when its output port is pulled.
For	A loop control. The Body branch is executed, providing an Index equal to First. If execution isn't interrupted (for example, by Break), the Index is incremented by Step. If the Index is less than Last, the Body branch is executed again. This process repeats until the Index is greater than Last, at which point the Exit branch is executed and the loop terminates.
ForEach	A loop control that executes Body once for every item (provided as Item) contained in the provided collection. Once completed, the Exit branch is executed.
Once	Flow node with an internal state that triggers its output only the first time it is entered. Entering a second time does not trigger the output flow. After a reset, the next time you enter, will trigger the output flow.

SwitchOnInteger	Flow branching based on an input integer.
SwitchOnString	Flow branching based on an input string.
Throw	Causes an exception with the provided message.
ToggleFlow	Flow branching based on whether the node is On or Off, with inputs to set or toggle its On/Off state.
ToggleValue	Flow branching based on whether a value got set to its associated On/Off value.
TryCatch	Executes the Try branch. If an exception occurs in that branch, execute the Catch branch. Once the Try branch completes without exceptions or the Catch branch completes, the Finally branch is executed.
While	Executes the Body branch. Repeat this step as long as the provide condition is true. When that condition is no longer true, execute the Exit branch.
