Class Sequence

java.lang.Object
  de.mguennewig.pobjects.metadata.Sequence

All Implemented Interfaces:

SqlEntity

public class Sequence
extends java.lang.Object
implements SqlEntity

Provides the parameters needed to maintain an automatically generated primary key for the table rows.

Id's are generated from sequences and are never reused. That is, for a given table an id value identifies exactly one row, even past the lifetime of the row.

Multiple class definitions may use the same sequence.
