Class Constraint

java.lang.Object
  net.sourceforge.jdbdump.dump.Constraint

All Implemented Interfaces:

java.io.Serializable

public class Constraint
extends java.lang.Object
implements java.io.Serializable

Represents a table or column constraint.

A constraint can be assigned either to a single column (e.g. "..., cash integer CHECK (cash > 0), ...") or to the entire table (e.g. "..., CONSTRAINT table_pkey PRIMARY KEY (id), ..."). It has three attributes: its name (not always used, in the second example that would be "table_pkey"), its text (entire SQL expression used in create table command), and its type which can be PRIMARE_KEY, FOREIGN_KEY or OTHER.
