Given are the two unrelated classes Person and DetailedPerson.

mapEqualNames()

anInputPerson {
     age: 45,
     name: "Jane",
     surname: "Doe",
     city: "Los Angeles",
     country: "USA",
     street: "22, Main Road",
     zip: 90077

The object anInputPerson is of type DetailedPerson.

Code Block

language	none

set anOutputPerson = mapEqualNames(anInputPerson);

This statement assigns values to the matching attributes of object anOutputPerson which is of type Person:

anOutputPerson {
      name: "Jane",
      surname: "Doe",
      city: "Los Angeles",
      street: "22, Main Road",
      zip: 90077
}

mapEqualNamesIfExists()

aPerson {
     name: "John Ethan George",
     surname: "Smith",
     city: "New York",
     street: "65, Upper Eastside",
     zip: 0
}

The object aPerson of type Person already contains values.
In our example, the zip code is unknown, so the attribute zip contains the value 0.

anotherInputPerson {
     age: 32,
     name: "John",
     surname: "Smith",
     city: "New York",
     country: "USA",
     street: NULL,
     zip: 12345
}

The object anotherInputPerson is of type DetailedPerson.
In this example object, the attribute name street is missing.

Code Block

language	none

set aPerson = mapEqualNamesIfExists(anotherInputPerson);

This statement assigns values to the matching attributes of object aPerson:

aPerson {
      name: "John",
      surname: "Smith",
      city: "New York",
      street: "65, Upper Eastside",
      zip: 12345
}
The value of street remains unchanged, because in the source object it did not exist (was NULL).
