Enclosing class:

ImmutableVariables

public static final class ImmutableVariables.Builder
extends Object

Builds instances of type ImmutableVariables. 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.
