public Map<K,V> generate()

Description copied from interface: Generator

Depending on implementation, repeated invocations may return different values. Some implementations may return random values on each invocation, while others may return predefined values or random values from a given set.

Generators can be passed in as a lambda function. The following example shows how to override generation strategy for certain fields.

     Person person = Instancio.of(Person.class)
         .generate(field("age"), gen -> gen.oneOf(20, 30, 40, 50))
         .supply(field("location"), () -> "Canada")
         .supply(all(LocalDateTime.class), () -> LocalDateTime.now())
         .create();
 

Specified by:

generate in interface Generator<K>

Overrides:

generate in class MapGenerator<K,V>

Returns:

generated value
