TypeKey (Objectify App Engine 6.0.7 API)

java.lang.Object
- com.googlecode.objectify.impl.translate.TypeKey<T>

```
public class TypeKey<T>
extends Object
```
Unique identifier for a translator instance. Important so we can re-use translators as we navigate the tree, allowing us to store recursive structures.

Constructor Summary

Constructors
Constructor	Description
`TypeKey(Property prop)`	Create a typekey from a property
`TypeKey(Type type)`
`TypeKey(Type type, TypeKey previous)`	Create a new typekey for a new type but which preserves characteristics of the old typekey (ie annotations).

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`<A extends Annotation> A`	`getAnnotation(Class<A> annotationType)`	Gets the annotation that has the specified type, or null if there isn't one
`<A extends Annotation> A`	`getAnnotationAnywhere(Class<A> annotationType)`	Checks not only the listed annotations but also annotations on the class.
`Class<T>`	`getTypeAsClass()`	Get the basic class through erasure.
`boolean`	`isAnnotationPresent(Class<? extends Annotation> annotationType)`
`boolean`	`isAssignableTo(Class<?> superclass)`	Can this type be assigned to a variable with the specified type? This is the inverse of isAssignableFrom().

  - TypeKey
```
public TypeKey(Type type,
               TypeKey previous)
```
    Create a new typekey for a new type but which preserves characteristics of the old typekey (ie annotations). This is used when creating a new typekey for component types.

  - getTypeAsClass
```
public Class<T> getTypeAsClass()
```
    Get the basic class through erasure.
  - getAnnotation
```
public <A extends Annotation> A getAnnotation(Class<A> annotationType)
```
    Gets the annotation that has the specified type, or null if there isn't one
  - isAnnotationPresent
```
public boolean isAnnotationPresent(Class<? extends Annotation> annotationType)
```
    Returns:
    
    true if the annotation is present
  - getAnnotationAnywhere
```
public <A extends Annotation> A getAnnotationAnywhere(Class<A> annotationType)
```
    Checks not only the listed annotations but also annotations on the class.
  - isAssignableTo
```
public boolean isAssignableTo(Class<?> superclass)
```
    Can this type be assigned to a variable with the specified type? This is the inverse of isAssignableFrom().
