Enum RetentionPolicy

Enum Constant Detail

• SOURCE

  public static final RetentionPolicy SOURCE

  Annotations are to be discarded by the compiler.

• CLASS

  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.

• RUNTIME

  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.
