By building upon 20 * <a href="https://jcp.org/en/jsr/detail?id=330">JSR 330</a>, Dagger 2 provides an 21 * annotation-driven API for dependency injection whose implementation is entirely generated at 22 * compile time by <a href="http://en.wikipedia.org/wiki/Java_annotation#Processing">annotation 23 * processors</a>. 24 * 25 * <p>The entry point into the API is the {@link Component}, which annotates abstract types for 26 * Dagger 2 to implement. The dependency graph is configured using using annotations such as 27 * {@link Module}, {@link Provides} and {@link javax.inject.Inject}. 28 * 29 * <p>{@code dagger.internal.codegen.ComponentProcessor} is the processor responsible for generating 30 * the implementation. Dagger uses the annotation procesor 31 * {@linkplain java.util.ServiceLoader service loader} to automatically configure the processor, so 32 * explict build configuration shouldn't be necessary. 33 */ 34 package dagger; 35
