Method Detail

visitOther

protected V visitOther()

Default visit implementation. Returns null.

visitEagerSingleton

public V visitEagerSingleton()

Description copied from interface: BindingScopingVisitor

Visit an eager singleton or single instance. This scope strategy is found on both module and injector bindings.

Specified by:

visitEagerSingleton in interface BindingScopingVisitor<V>

visitScope

public V visitScope(Scope scope)

Description copied from interface: BindingScopingVisitor

Visit a scope instance. This scope strategy is found on both module and injector bindings.

Specified by:

visitScope in interface BindingScopingVisitor<V>

visitScopeAnnotation

public V visitScopeAnnotation(Class<? extends Annotation> scopeAnnotation)

Description copied from interface: BindingScopingVisitor

Visit a scope annotation. This scope strategy is found only on module bindings. The instance that implements this scope is registered by Binder.bindScope().

Specified by:

visitScopeAnnotation in interface BindingScopingVisitor<V>

visitNoScoping

public V visitNoScoping()

Description copied from interface: BindingScopingVisitor

Visit an unspecified or unscoped strategy. On a module, this strategy indicates that the injector should use scoping annotations to find a scope. On an injector, it indicates that no scope is applied to the binding. An unscoped binding will behave like a scoped one when it is linked to a scoped binding.
