Methods
Modifier and Type	Method and Description
`<B,V> V`	`acceptExtensionVisitor(BindingTargetVisitor<B,V> visitor, ProviderInstanceBinding<? extends B> binding)` Instructs the extension determine if the visitor is an instance of a custom extension visitor, and if so, visit it using that method.
`void`	`configure(Binder binder)`
`boolean`	`equals(Object obj)`
`T`	`get()` Provides an instance of `T`.
`Annotation`	`getAnnotation()` Returns the annotation that caused this binding to be created.
`Set<Dependency<?>>`	`getDependencies()` Returns the known dependencies for this type.
`Object`	`getEnclosingInstance()` Returns the instance of the object the method is defined in.
`Object`	`getInstance()`
`Key<T>`	`getKey()` Returns the key of the binding.
`Method`	`getMethod()` Returns the method this binding uses.

  - getKey
```
public Key<T> getKey()
```
    Description copied from interface: ProvidesMethodBinding
    
    Returns the key of the binding.
    
    Specified by:
    
    getKey in interface ProvidesMethodBinding<T>
  - getMethod
```
public Method getMethod()
```
    Description copied from interface: ProvidesMethodBinding
    
    Returns the method this binding uses.
    
    Specified by:
    
    getMethod in interface ProvidesMethodBinding<T>
  - getInstance
```
public Object getInstance()
```
  - getEnclosingInstance
```
public Object getEnclosingInstance()
```
    Description copied from interface: ProvidesMethodBinding
    
    Returns the instance of the object the method is defined in.
    
    Specified by:
    
    getEnclosingInstance in interface ProvidesMethodBinding<T>
  - getAnnotation
```
public Annotation getAnnotation()
```
    Description copied from interface: ProvidesMethodBinding
    
    Returns the annotation that caused this binding to be created. For @Provides methods, this is an instance of the @Provides annotation. For bindings from ModuleAnnotatedMethodScanner, this is the annotation that caused the scanner to produce the binding.
    
    Specified by:
    
    getAnnotation in interface ProvidesMethodBinding<T>
  - configure
```
public void configure(Binder binder)
```
  - get
```
public T get()
```
    Description copied from interface: Provider
    
    Provides an instance of T. Must never return null.
    
    Specified by:
    
    get in interface javax.inject.Provider<T>
  - getDependencies
```
public Set<Dependency<?>> getDependencies()
```
    Description copied from interface: HasDependencies
    
    Returns the known dependencies for this type. If this has dependencies whose values are not known statically, a dependency for the Injector will be included in the returned set.
    
    Specified by:
    
    getDependencies in interface HasDependencies
    
    Returns:
    a possibly empty set
  - acceptExtensionVisitor
```
public <B,V> V acceptExtensionVisitor(BindingTargetVisitor<B,V> visitor,
                             ProviderInstanceBinding<? extends B> binding)
```
    Description copied from interface: ProviderWithExtensionVisitor
    
    Instructs the extension determine if the visitor is an instance of a custom extension visitor, and if so, visit it using that method. If the visitor is not an instance of the custom extension visitor, this method MUST call visitor.visit(binding).
    Due to issues with generics, the type parameters of this method do not relate to the type of the provider. In practice, the 'B' type will always be a supertype of 'T'.
    
    Specified by:
    
    acceptExtensionVisitor in interface ProviderWithExtensionVisitor<T>
  - toString
```
public String toString()
