RetentionPolicy

public final enum RetentionPolicy extends Enum<RetentionPolicy>

Annotation retention policy. The constants of this enumerated type describe the various policies for retaining annotations. They are used in conjunction with the Retention meta-annotation type to specify how long annotations are to be retained.

final Object	clone() Throws CloneNotSupportedException.
final int	compareTo(RetentionPolicy o) Compares this enum with the specified object for order.
final boolean	equals(Object other) Returns true if the specified object is equal to this enum constant.

final Class<RetentionPolicy>	getDeclaringClass() Returns the Class object corresponding to this enum constant's enum type.
final int	hashCode() Returns a hash code for this enum constant.
final String	name() Returns the name of this enum constant, exactly as declared in its enum declaration.
final int	ordinal() Returns the ordinal of this enumeration constant (its position in its enum declaration, where the initial constant is assigned an ordinal of zero).

int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait(long timeout, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.

Enum Values

public static final RetentionPolicy CLASS

Annotations are to be recorded in the class file by the compiler but need not be retained by the VM at run time. This is the default behavior.

public static final RetentionPolicy RUNTIME

Annotations are to be recorded in the class file by the compiler and retained by the VM at run time, so they may be read reflectively.
