All Implemented Interfaces:

AnnotationTarget

Direct Known Subclasses:

EmptyTypeTarget, PositionBasedTypeTarget
```
public abstract class TypeTarget
extends java.lang.Object
implements AnnotationTarget
```
Represents a type that is the target of a type annotation. Type annotations can occur at any nesting level on any type declaration. For this reason, an enclosing target is provided, as well as other usage specific information to determine the starting point for locating the type.
It is expected that callers will traverse the full tree from the specified starting point, since this context is important in interpreting the meaning of the type annotation

Since:

2.0

    Description copied from interface: AnnotationTarget
    
    Returns the kind of object this target represents.
    
    Specified by:
    
    kind in interface AnnotationTarget
    
    Returns:
    
    the target kind.
  - enclosingTarget
```
public AnnotationTarget enclosingTarget()
```
    Returns the enclosing target that contains the type referred to by the target() method.
    
    Returns:
    
    the enclosing target
  - target
```
public Type target()
```
    Returns the type which contains the respective annotation. In some cases this may be null (e.g. in the case of a bridge method, which erases type information so there is no target to map to)
    
    Returns:
    
    the type containing the respective annotation
  - usage
```
public abstract TypeTarget.Usage usage()
```
    Returns the kind of usage of this type target. This allows a caller to use a switch statement as opposed to getClass() comparisons.
    
    Returns:
    
    the kind of usage of this type target
  - asEmpty
```
public EmptyTypeTarget asEmpty()
```
  - asClassExtends
```
public ClassExtendsTypeTarget asClassExtends()
```
    Casts and returns this type target as a ClassExtendsTypeTarget. If this type target is not a ClassExtendsTypeTarget, then an exception will be thrown.
    
    Returns:
    
    an instance of ClassExtendsTypeTarget
