Enclosing class:

ImmutableMappedValue<T>

@NotThreadSafe
public static final class ImmutableMappedValue.Builder<T>
extends Object

Builds instances of type ImmutableMappedValue. Initialize attributes and then invoke the build() method to create an immutable instance.

Builder is not thread-safe and generally should not be stored in a field or collection, but instead used immediately to create instances.
