Represents design time metadata about a variable.

OdiVariable class is the only member of OdiVariable aggregate, thus it is the root entity and implements IOdiEntity interface. An OdiVariable has an ID that can be obtained from getVariableId() method call. This ID is assigned when an OdiVariable is stored in design time repository. This ID represents the identity of an OdiVariable. Equals / hashCode method are implemented according this identity.

There is two distinct scopes of OdiVariable: Global and Project.

• Global Scope OdiVariable are not bound to a given project and can be used in every OdiInterfaces or OdiPackages.
• Project Scope OdiVariable are bound to a single OdiProject and can only be used inside OdiInterfaces or OdiPackages of the same OdiProject.

Scope of an OdiVariable cannot be changed.

Life cycle of an OdiVariable begins at design time when it is created from one of its constructors, or when imported from external XML file. It is then typically stored inside ODI design time repository. The users can modify it in order to make it fit their needs. Life cycle ends when a user remove the OdiVariable instance from design time repository, or if enclosing OdiProject is removed (Project Scope).

getInternalId

public java.io.Serializable getInternalId()

Description copied from interface: IRepositoryEntity

Provides a common getter for the persistence layer to obtain an identity, irrespective of the actual type of identity used.

Typically a subclass will delegate to a public SomePrimitiveWrapper getId() method. The necessity for the getInternalId() abstract method is solely because the persistence layer needs a way of obtaining the identity irrespective of the actual identity implementation choice.

Returning null from this method will indicate the object has never been saved. This will likely be relied on by some DAO implementations.

Specified by:

getInternalId in interface IRepositoryEntity

Returns:

the persistence identity of this instance
