メソッドの詳細

getSource

public Object getSource()

インタフェースからコピーされた説明: Element

Returns an arbitrary object containing information about the "place" where this element was configured. Used by Guice in the production of descriptive error messages.

Tools might specially handle types they know about; StackTraceElement is a good example. Tools should simply call toString() on the source object if the type is unfamiliar.

定義:

getSource インタフェース内 Element

getType

public TypeLiteral<T> getType()

Gets the type containing the members to be injected.

acceptVisitor

public <T> T acceptVisitor(ElementVisitor<T> visitor)

インタフェースからコピーされた説明: Element

Accepts an element visitor. Invokes the visitor method specific to this element's type.

定義:

acceptVisitor インタフェース内 Element

パラメータ:

visitor - to call back on

initializeDelegate

public void initializeDelegate(MembersInjector<T> delegate)

Sets the actual members injector.

例外:

IllegalStateException - if the delegate is already set

applyTo

public void applyTo(Binder binder)

インタフェースからコピーされた説明: Element

Writes this module element to the given binder (optional operation).

定義:

applyTo インタフェース内 Element

パラメータ:

binder - to apply configuration element to

getDelegate

public MembersInjector<T> getDelegate()

Returns the delegate members injector, or null if it has not yet been initialized. The delegate will be initialized when this element is processed, or otherwise used to create an injector.

getMembersInjector

public MembersInjector<T> getMembersInjector()

Returns the looked up members injector. The result is not valid until this lookup has been initialized, which usually happens when the injector is created. The members injector will throw an IllegalStateException if you try to use it beforehand.
