Class GuidGeneratorWithTime

java.lang.Object

com.adaptris.util.GuidGenerator

com.adaptris.util.GuidGeneratorWithTime

All Implemented Interfaces:

IdGenerator

@ComponentProfile(summary="unique id generator that is globally unique, but contains a time component",
                  since="3.9.1")
public class GuidGeneratorWithTime
extends GuidGenerator

Generates a unique id that is still globally unique similar to GuidGenerator but contains a date/time component.

You can use this IdGenerator if you need to record the date that a GUID was generated. The date that the GUID was generated can be found using the computeTime(String) method.

Since:

3.9.1

In the adapter configuration file this class is aliased as guid-generator-with-time which is the preferred alternative to the fully qualified classname when building your configuration.
