public class: Inject [javadoc | source]

com.google.inject.Inject

Annotates members of your implementation class (constructors, methods and fields) into which the Injector should inject values. The Injector fulfills injection requests for:

Every instance it constructs. The class being constructed must have exactly one of its constructors marked with {@code @Inject} or must have a constructor taking no parameters. The Injector then proceeds to perform method and field injections.
Pre-constructed instances passed to Injector#injectMembers , com.google.inject.binder.LinkedBindingBuilder#toInstance(Object) and com.google.inject.binder.LinkedBindingBuilder#toProvider(Provider) . In this case all constructors are, of course, ignored.
Static fields and methods of classes which any Module has specifically requested static injection for, using Binder#requestStaticInjection .

In all cases, a member can be injected regardless of its Java access specifier (private, default, protected, public).

Method from com.google.inject.Inject Summary:
optional

Method from com.google.inject.Inject Detail:
boolean optional() { } If true, and the appropriate binding is not found, the Injector will skip injection of this method or field rather than produce an error. When applied to a field, any default value already assigned to the field will remain (guice will not actively null out the field). When applied to a method, the method will only be invoked if bindings for all parameters are found. When applied to a constructor, an error will result upon Injector creation.
