Class InternalProviderInstanceBindingImpl.Factory<T>

java.lang.Object

com.google.inject.internal.InternalProviderInstanceBindingImpl.Factory<T>

All Implemented Interfaces:

InternalFactory<T>, HasDependencies, javax.inject.Provider<T>

Direct Known Subclasses:

InternalProviderInstanceBindingImpl.CyclicFactory, RealMapBinder.ProviderMapEntry, RealMapBinder.RealMapBinderProviderWithDependencies, RealMapBinder.RealMultimapBinderProviderWithDependencies, RealMultibinder.RealMultibinderCollectionOfProvidersProvider, RealMultibinder.RealMultibinderProvider, RealOptionalBinder.RealOptionalBinderProviderWithDependencies

Enclosing class:

InternalProviderInstanceBindingImpl<T>

abstract static class InternalProviderInstanceBindingImpl.Factory<T>
extends java.lang.Object
implements InternalFactory<T>, Provider<T>, HasDependencies

A base factory implementation. Any Factories that delegate to other bindings should use the CyclicFactory subclass, but trivial factories can use this one.

Method Detail

getSource

final java.lang.Object getSource()

The binding source.

May be useful for augmenting runtime error messages.

Note: this will return {#code null} until initialize(InjectorImpl, Errors) has already been called.

initialize

abstract void initialize(InjectorImpl injector,
                         Errors errors)
                  throws ErrorsException

A callback that allows for implementations to fetch dependencies on other bindings.

Will be called exactly once, prior to any call to doProvision(com.google.inject.internal.InternalContext, com.google.inject.spi.Dependency<?>).

Throws:

ErrorsException

get

public final T get()

Description copied from interface: Provider

Provides an instance of T.

Specified by:

get in interface javax.inject.Provider<T>

get

public T get(InternalContext context,
             Dependency<?> dependency,
             boolean linked)
      throws InternalProvisionException

Description copied from interface: InternalFactory

Creates an object to be injected.

Specified by:

get in interface InternalFactory<T>

Parameters:

context - of this injection

linked - true if getting as a result of a linked binding

Returns:

instance that was created

Throws:

InternalProvisionException - if a value cannot be provided

doProvision

protected abstract T doProvision(InternalContext context,
                                 Dependency<?> dependency)
                          throws InternalProvisionException

Creates an object to be injected.

Returns:

instance to be injected

Throws:

InternalProvisionException - if a value cannot be provided
