Specifies the scope for this selector in order to narrow down its target.For example, given the following classes:
record Phone(String countryCode, String number) {} record Person(Phone home, Phone cell) {}
setting
home
andcell
phone numbers to different values would require differentiating between twofield(Phone::number)
selectors. This can be achieved using scopes as follows:Scope homePhone = field(Person::home).toScope(); Scope cellPhone = field(Person::cell).toScope(); Person person = Instancio.of(Person.class) .set(field(Phone::number).within(homePhone), "777-88-99") .set(field(Phone::number).within(cellPhone), "123-45-67") .create();
See Selector Scopes section of the user guide for details.
