public 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.
public static final RetentionPolicy SOURCE
Annotations are to be discarded by the compiler.
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.
public static RetentionPolicy 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 (RetentionPolicy c : RetentionPolicy.values()) System.out.println(c);
public static RetentionPolicy valueOf(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.)
name- the name of the enum constant to be returned.
IllegalArgumentException- if this enum type has no constant with the specified name
NullPointerException- if the argument is null
