Class DBObjectDeclarationFactory

java.lang.Object

oracle.jdeveloper.db.dependency.DBObjectDeclarationFactory

public final class DBObjectDeclarationFactory
extends java.lang.Object

This factory is used to create Declaration implementations for database objects in the IDE. They are based on declaration ids - strings to be used with the IDE's IdDeclaration and IdReference.

Examples:
(Column, Table and DBObjectProvider are all in package oracle.javatools.db)

1) Create a reference to table "EMP" in schema "SCOTT" in a given DBObjectProvider (pro):

   DBObjectDeclarationFactory factory = DBObjectDeclarationFactory.getInstance();
   DBObjectDeclaration decl =
      factory.createDeclaration( pro, "SCOTT", Table.TYPE, "EMP" );
 

2) Create a reference to column "ENAME" in table "EMP" using the default schema a DBObjectProvider (pro):

   DBObjectDeclarationFactory factory = DBObjectDeclarationFactory.getInstance();
   DBObjectDeclaration decl =
     factory.createDelcaration( pro, null, Table.TYPE, "EMP", Column.TYPE, "ENAME" );
 

Since:

11.1.1.2.0
