Package com.google.inject.internal

Class DynamicClassProvider

  • All Implemented Interfaces:
    com.google.inject.Provider<java.lang.Object>, javax.inject.Provider<java.lang.Object>
    Direct Known Subclasses:
    DynamicSingletonProvider
    @Singleton
public class DynamicClassProvider
extends java.lang.Object
implements com.google.inject.Provider<java.lang.Object>
    Provider allows using interfaces or abstract classes as normal guice beans. Simply annotate interface or abstract class with @ProvidedBy(DynamicClassProvider.class) and use it as usual guice bean.

    Original bean will be correctly handled by guice aop: provider will generate new class, which guice could use for proxy generation.

    If used with injectors hierarchy or within private modules, use together with GeneratorAnchorModule to properly scope dynamic bindings.

    Providers use guice package to use internal guice api (to resolve actual required type)
