Annotation Type Persist

@Target(value=FIELD)
 @Retention(value=RUNTIME)
 @Documented
public @interface Persist

Fields annotated by this annotation have their value persisted in a local file.

At startup, when Agent.start() is called, the file is read and persisted values are applied to the corresponding field.

To trigger the local persistence of annotated fields, invoke org.lsst.ccs.framework.Subsystem#persistNow

Supported annotated field types are the same as the ones supported by the configuration service since serialization/deserialization relies on org.lsst.ccs.utilities.conv.TypeUtils#stringify and org.lsst.ccs.utilities.conv.InputConversionEngine#convertArgToType.
