MergeBranches
Chooses the first non-Nil object, or reports an error if there is no such object.
| Name | Type | Description | |
|---|---|---|---|
 |
inConditionalObject1 | <T>? | First conditional input object |
|
inConditionalObject2 | <T>? | Second conditional input object |
|
inConditionalObject3 | <T>? | Third conditional input object |
|
inConditionalObject4 | <T>? | Fourth conditional input object |
|
inConditionalObject5 | <T>? | Fifth conditional input object |
|
inConditionalObject6 | <T>? | Sixth conditional input object |
|
inConditionalObject7 | <T>? | Seventh conditional input object |
|
inConditionalObject8 | <T>? | Eighth conditional input object |
 |
outObject | <T> | First not-Nil input object |
The type of this filter is defined using the type variable T which represents any valid type. Read more.
Description
The operation collects a number of conditional objects and passes the existing input values onto the outObject output. The filter assumes that at least one of the input values exists; otherwise an error with appropriate description occurs.
The operation is similar to the MergeConditionals filter, yet it computes the proper (non-conditional) object.
Examples
|
|
|
inConditionalObject1 = Nil inConditionalObject2 = Nil inConditionalObject3 = "Mike" inConditionalObject4 = "Alice" inConditionalObject5 = Nil inConditionalObject6 = "Joanne" inConditionalObject7 = Nil inConditionalObject8 = Nil |
outObject = "Mike" |
|
|
|
inConditionalObject1 = Nil inConditionalObject2 = Nil inConditionalObject3 = Nil inConditionalObject4 = Nil inConditionalObject5 = Nil inConditionalObject6 = Nil inConditionalObject7 = Nil inConditionalObject8 = Nil |
Error occurs. |
Errors
This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
List of possible exceptions:
| Error type | Description |
|---|---|
| DomainError | All of the conditional objects on input are Nil in MergeBranches. |
