UniversalFlowInputOutput

STATUS: ACTIVE

This is a common object for passing data from a flow, into a class method, and back out to flow.

Constructors

public UniversalFlowInputOutput()

Flow requires a 0 argument constructor, so we provide one here.

public UniversalFlowInputOutput(String className, String methodName, Object returnValue, Boolean isError)

This constructor variant is used by this class, and the the UniversalInvocable class to construct the return object.

Parameters

Param	Description
className	String Name of the class called
methodName	String Name of the method called
returnValue	UniversalFlowInputOutputParameter The return value of the called method is automatically cast to it's respective primitive type and stored in this object.
isError	boolean If the method called threw an exception, this should be true. Otherwise, false.

Fields

public className → String

AURAENABLED INVOCABLEVARIABLE

String representing Apex recognized name of the class you're instantiating.

public methodName → String

AURAENABLED INVOCABLEVARIABLE

String representing the method name you're calling

public parameters → List<UniversalFlowInputOutputParameter>

AURAENABLED INVOCABLEVARIABLE

This is a list of individual parameters you're passing to the method you're calling.

public result → UniversalFlowInputOutputParameter

AURAENABLED INVOCABLEVARIABLE

While the parameters list is used for passing parameters to the method you're calling, this single object is used for passing the return value of the method you're calling back to flow. As a side effect of the way this works, you can build aggregating methods that call multiple methods and return multiple values - of different types - to the flow via this object.

public success → Boolean

AURAENABLED INVOCABLEVARIABLE

Methods

public Map toCallableParamMap()

Method is responsible for converting the list of UniversalFlowInputOutputParameter objects delivered by the Flow action framework, to a Map<String, Object> needed by the Callable interface. Note, this is a hard limitation of the Flow action framework and the Apex Defined Data Types. This is not a limitation of this pattern / framework. If you want to, say pass a list of records to a method, you'll need to pass a list of strings, and query for the objects in the Apex. #sorryNothingICanDo.

Returns

Type	Description
Map<String,Object>	Map<String, Object> This returns a map of parameters you're passing to your method.

public override String toString()

Used to provide a usable key for the Map that uses this method.

Returns

Type	Description
String	String This value maps unique class/method names
