Binding

```
public interface Binding
```
The association between a Key and the way in which instances of the key are provided. Includes any dependencies that are needed in order to provide the instances.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`java.util.Optional<? extends javax.lang.model.element.Element>`	`bindingElement()` The `Element` that declares this binding.
`java.util.Optional<javax.lang.model.element.TypeElement>`	`contributingModule()` The `TypeElement` of the module which contributes this binding.
`com.google.common.collect.ImmutableSet<DependencyRequest>`	`dependencies()` The dependencies of this binding.
`boolean`	`isNullable()` Returns `true` if this binding may provide `null` instead of an instance of `key()`.
`boolean`	`isProduction()` Returns `true` if this is a production binding, e.g.
`Key`	`key()` The binding's key.
`BindingKind`	`kind()` The kind of binding this instance represents.
`java.util.Optional<Scope>`	`scope()` The scope of this binding if it has one.

- Method Detail
  - key
```
Key key()
```
    The binding's key.
  - dependencies
```
com.google.common.collect.ImmutableSet<DependencyRequest> dependencies()
```
    The dependencies of this binding. The order of the dependencies corresponds to the order in which they will be injected when the binding is requested.
  - bindingElement
```
java.util.Optional<? extends javax.lang.model.element.Element> bindingElement()
```
    The Element that declares this binding. Absent for binding kinds that are not always declared by exactly one element.
    For example, consider BindingKind.MULTIBOUND_SET. A component with many @IntoSet bindings for the same key will have a synthetic binding that depends on all contributions, but with no identifiying binding element. A @Multibinds method will also contribute a synthetic binding, but since multiple @Multibinds methods can coexist in the same component (and contribute to one single binding), it has no binding element.
  - contributingModule
```
java.util.Optional<javax.lang.model.element.TypeElement> contributingModule()
```
    The TypeElement of the module which contributes this binding. Absent for bindings that have no binding element.
  - scope
```
java.util.Optional<Scope> scope()
```
    The scope of this binding if it has one.
  - isNullable
```
boolean isNullable()
```
    Returns true if this binding may provide null instead of an instance of key(). Nullable bindings cannot be requested from non-nullable dependency requests.
  - isProduction
```
boolean isProduction()
```
    Returns true if this is a production binding, e.g. an @Produces method.
  - kind
```
BindingKind kind()
```
    The kind of binding this instance represents.
