An intermediary builder type used while building an IfFlow.
IfChain represents a conditional structure consisting of an initial ifThen clause and optional elseIfThens. It does not include an elseThen clause. An IfChain can be converted into a complete IfFlow by adding an orElse clause via its extension function.
If the condition of the primary ifThen is true, its associated node is executed. Otherwise, the elseIfThens are evaluated in order. If any IfThen condition in elseIfThens is true, its associated node is executed, and subsequent conditions are skipped. If no condition is met, execution continues to the Node following this IfChain in the parent SequentialFlow.
Subsequent conditional clauses in the IfChain. These will execute in order if the first IfThen is false. If any IfThen condition is true, its associated node is executed, and the rest of the conditions are not evaluated.
