Class Relation

java.lang.Object
  org.utgenome.gwt.utgb.client.db.Relation

All Implemented Interfaces:

com.google.gwt.user.client.rpc.IsSerializable

public class Relation
extends Object
implements com.google.gwt.user.client.rpc.IsSerializable

A Relation holds one or more DataTypes and denotes their relationships. For example, in relational databases, a table has a structure, e.g. (pid:integer, name:string, address:string) You can construct this structure as follows: Relation r = new Relation(); r.add("pid", new IntegerType()); r.add("name", new StringType()); r.add("address", new StringType()); JSON format example. {"relation":[["id", "integer"], ["name", "string"], ...]}
