/**
 * Implementation of SourceProviderContainer that is serializable and is meant to be used
 * in the model sent to the tooling API.
 *
 * It also provides convenient methods to create an instance, cloning the original
 * SourceProvider.
 *
 * When the source Provider is cloned, its values are queried and then statically stored.
 * Any further change through the DSL will not be impact. Therefore instances of this class
 * should only be used when the model is built.
 *
 * To create more dynamic isntances of SourceProviderContainer, use
 * {@link com.android.build.gradle.internal.variant.DefaultSourceProviderContainer}
