- Method Detail
  - values
```
public static JavaType[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (JavaType c : JavaType.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static JavaType valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - getTypeStub
```
public TypeDescription getTypeStub()
```
    Returns at least a stub representing this type where the stub does not define any methods or fields. If a type exists for the current runtime, a loaded type representation is returned.
    
    Returns:
    
    A type description for this Java type.
  - load
```
@Enhance("loaded")
public java.lang.Class<?> load()
                        throws java.lang.ClassNotFoundException
```
    Loads the class that is represented by this Java type.
    
    Returns:
    
    A loaded type of this Java type.
    
    Throws:
    
    java.lang.ClassNotFoundException - If the represented type cannot be loaded.
  - loadAsDescription
```
public TypeDescription loadAsDescription()
                                  throws java.lang.ClassNotFoundException
```
    Loads the class that is represented by this Java type and represents it as a TypeDescription.
    
    Returns:
    
    A loaded type of this Java type.
    
    Throws:
    
    java.lang.ClassNotFoundException - If the represented type cannot be loaded.
  - isAvailable
```
public boolean isAvailable()
```
    Returns true if this type is available on the current JVM.
    
    Returns:
    
    true if this type is available on the current JVM.
  - doIsAvailable
```
@Enhance("available")
private java.lang.Boolean doIsAvailable()
```
    Returns true if this type is available on the current VM. By boxing the result, the result can be cached efficiently what is not possible when using a primitive type.
    
    Returns:
    
    true if this type is available on the current JVM.
  - isInstance
```
public boolean isInstance(java.lang.Object instance)
```
    Checks if the supplied object is an instance of this type.
    
    Parameters:
    
    instance - The instance to check.
