Class ImmutableHelper.Builder

java.lang.Object

de.flapdoodle.transition.processlike.ImmutableHelper.Builder

All Implemented Interfaces:

ProcessListener.Helper.Builder

Enclosing class:

ImmutableHelper

public static final class ImmutableHelper.Builder
extends Object
implements ProcessListener.Helper.Builder

Builds instances of type ImmutableHelper. 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.
