InjectionPoint (Guice 4.1 API)

java.lang.Object
- com.google.inject.spi.InjectionPoint

```
public final class InjectionPoint
extends Object
```
A constructor, field or method that can receive injections. Typically this is a member with the @Inject annotation. For non-private, no argument constructors, the member may omit the annotation.

2.0

- Method Detail
  - getMember
```
public Member getMember()
```
    Returns the injected constructor, field, or method.
  - getDependencies
```
public List<Dependency<?>> getDependencies()
```
    Returns the dependencies for this injection point. If the injection point is for a method or constructor, the dependencies will correspond to that member's parameters. Field injection points always have a single dependency for the field itself.
    
    Returns:
    
    a possibly-empty list
  - isOptional
```
public boolean isOptional()
```
    Returns true if this injection point shall be skipped if the injector cannot resolve bindings for all required dependencies. Both explicit bindings (as specified in a module), and implicit bindings (@ImplementedBy, default constructors etc.) may be used to satisfy optional injection points.
  - isToolable
```
public boolean isToolable()
```
    Returns true if the element is annotated with @Toolable.
    
    Since:
    
    3.0
  - getDeclaringType
```
public TypeLiteral<?> getDeclaringType()
```
    Returns the generic type that defines this injection point. If the member exists on a parameterized type, the result will include more type information than the member's raw declaring class.
    
    Since:
    
    3.0
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - forConstructor
```
public static <T> InjectionPoint forConstructor(Constructor<T> constructor)
```
    Returns a new injection point for the specified constructor. If the declaring type of constructor is parameterized (such as List<T>), prefer the overload that includes a type literal.
    
    Parameters:
    
    constructor - any single constructor present on type.
    
    Since:
    
    3.0
  - forConstructor
```
public static <T> InjectionPoint forConstructor(Constructor<T> constructor,
                                                TypeLiteral<? extends T> type)
```
    Returns a new injection point for the specified constructor of type.
    
    Parameters:
    
    constructor - any single constructor present on type.
    
    type - the concrete type that defines constructor.
    
    Since:
    
    3.0
  - forConstructorOf
```
public static InjectionPoint forConstructorOf(TypeLiteral<?> type)
```
    Returns a new injection point for the injectable constructor of type.
    
    Parameters:
    
    type - a concrete type with exactly one constructor annotated @Inject, or a no-arguments constructor that is not private.
    
    Throws:
    
    ConfigurationException - if there is no injectable constructor, more than one injectable constructor, or if parameters of the injectable constructor are malformed, such as a parameter with multiple binding annotations.
  - forConstructorOf
```
public static InjectionPoint forConstructorOf(Class<?> type)
```
    Returns a new injection point for the injectable constructor of type.
    
    Parameters:
    
    type - a concrete type with exactly one constructor annotated @Inject, or a no-arguments constructor that is not private.
    
    Throws:
    
    ConfigurationException - if there is no injectable constructor, more than one injectable constructor, or if parameters of the injectable constructor are malformed, such as a parameter with multiple binding annotations.
  - forMethod
```
public static <T> InjectionPoint forMethod(Method method,
                                           TypeLiteral<T> type)
```
    Returns a new injection point for the specified method of type. This is useful for extensions that need to build dependency graphs from arbitrary methods.
    
    Parameters:
    
    method - any single method present on type.
    
    type - the concrete type that defines method.
    
    Since:
    
    4.0
  - forStaticMethodsAndFields
```
public static Set<InjectionPoint> forStaticMethodsAndFields(TypeLiteral<?> type)
```
    Returns all static method and field injection points on type.
    
    Returns:
    
    a possibly empty set of injection points. The set has a specified iteration order. All fields are returned and then all methods. Within the fields, supertype fields are returned before subtype fields. Similarly, supertype methods are returned before subtype methods.
    
    Throws:
    
    ConfigurationException - if there is a malformed injection point on type, such as a field with multiple binding annotations. The exception's partial value is a Set<InjectionPoint> of the valid injection points.
  - forStaticMethodsAndFields
```
public static Set<InjectionPoint> forStaticMethodsAndFields(Class<?> type)
```
    Returns all static method and field injection points on type.
    
    Returns:
    
    a possibly empty set of injection points. The set has a specified iteration order. All fields are returned and then all methods. Within the fields, supertype fields are returned before subtype fields. Similarly, supertype methods are returned before subtype methods.
    
    Throws:
    
    ConfigurationException - if there is a malformed injection point on type, such as a field with multiple binding annotations. The exception's partial value is a Set<InjectionPoint> of the valid injection points.
  - forInstanceMethodsAndFields
```
public static Set<InjectionPoint> forInstanceMethodsAndFields(TypeLiteral<?> type)
```
    Returns all instance method and field injection points on type.
    
    Returns:
    
    a possibly empty set of injection points. The set has a specified iteration order. All fields are returned and then all methods. Within the fields, supertype fields are returned before subtype fields. Similarly, supertype methods are returned before subtype methods.
    
    Throws:
    
    ConfigurationException - if there is a malformed injection point on type, such as a field with multiple binding annotations. The exception's partial value is a Set<InjectionPoint> of the valid injection points.
  - forInstanceMethodsAndFields
```
public static Set<InjectionPoint> forInstanceMethodsAndFields(Class<?> type)
```
    Returns all instance method and field injection points on type.
    
    Returns:
    
    a possibly empty set of injection points. The set has a specified iteration order. All fields are returned and then all methods. Within the fields, supertype fields are returned before subtype fields. Similarly, supertype methods are returned before subtype methods.
