VKey

java.lang.Object
- google.registry.model.ImmutableObject
- - google.registry.persistence.VKey<T>

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable
```
public class VKey<T>
extends ImmutableObject
implements java.io.Serializable
```
VKey is an abstraction that encapsulates the key concept.
A VKey instance must contain the JPA primary key for the referenced entity class.

- Method Detail
  - create
```
public static <T> VKey<T> create(java.lang.Class<T> kind,
                                 java.io.Serializable key)
```
    Creates a VKey with supplied the SQL primary key.
  - createEppVKeyFromString
```
public static <T extends EppResource> VKey<T> createEppVKeyFromString(java.lang.String keyString)
```
    Constructs a VKey for an EppResource from the string representation.
    The string representation is obtained from the stringify() function and like this: kind:SomeEntity@sql:rO0ABXQAA2Zvbw
  - getKind
```
public java.lang.Class<? extends T> getKind()
```
    Returns the type of the entity.
  - getKey
```
public java.io.Serializable getKey()
```
    Returns the primary key.
  - stringify
```
public java.lang.String stringify()
```
    Constructs the string representation of a VKey.
    The string representation contains its kind and Base64 SQL key, in the following format: kind:class_name@sql:encoded_sqlKey.
  - toString
```
public java.lang.String toString()
```
    Constructs the readable string representation of a VKey.
    
    Overrides:
    
    toString in class ImmutableObject
