Binding

All Superinterfaces:

BindingGraph.MaybeBinding, BindingGraph.Node
```
public interface Binding
extends BindingGraph.MaybeBinding
```
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.
If a binding is owned by more than one component, there is one Binding for every owning component.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods Deprecated Methods
Modifier and Type	Method and Description
`default java.util.Optional<Binding>`	`binding()` Deprecated. This always returns `Optional.of(this)`.
`java.util.Optional<DaggerElement>`	`bindingElement()` The `DaggerElement` that declares this binding.
`ComponentPath`	`componentPath()` The component that owns the binding, or in which the binding is missing.
`java.util.Optional<DaggerTypeElement>`	`contributingModule()` The `DaggerTypeElement` 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 `BindingGraph.MaybeBinding.key()`.
`boolean`	`isProduction()` Returns `true` if this is a production binding, e.g.
`BindingKind`	`kind()` The kind of binding this instance represents.
`boolean`	`requiresModuleInstance()` Returns `true` if using this binding requires an instance of the `contributingModule()`.
`java.util.Optional<Scope>`	`scope()` The scope of this binding if it has one.

  - componentPath
```
ComponentPath componentPath()
```
    Description copied from interface: BindingGraph.MaybeBinding
    
    The component that owns the binding, or in which the binding is missing.
    
    Specified by:
    
    componentPath in interface BindingGraph.MaybeBinding
    
    Specified by:
    
    componentPath in interface BindingGraph.Node
  - binding
```
@Deprecated
default java.util.Optional<Binding> binding()
```
    Deprecated. This always returns Optional.of(this).
    
    Description copied from interface: BindingGraph.MaybeBinding
    
    The binding, or empty if missing.
    
    Specified by:
    
    binding in interface BindingGraph.MaybeBinding
  - 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<DaggerElement> bindingElement()
```
    The DaggerElement 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<DaggerTypeElement> contributingModule()
```
    The DaggerTypeElement of the module which contributes this binding. Absent for bindings that have no binding element.
  - requiresModuleInstance
```
boolean requiresModuleInstance()
```
    Returns true if using this binding requires an instance of the contributingModule().
  - 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 BindingGraph.MaybeBinding.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.
