Class Overview
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.
Summary
| Enum Values |
|---|
| 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. |
| 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. |
| RetentionPolicy |
SOURCE |
Annotations are to be discarded by the compiler. |

Enum Values
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.
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.
Annotations are to be discarded by the compiler.
