de.flapdoodle.transition.initlike.ImmutableStateListener.Builder<T>

Enclosing class:

ImmutableStateListener<T>

public static final class ImmutableStateListener.Builder<T>
extends Object

Builds instances of type ImmutableStateListener. 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.
