public interface FileAttachableData
extends IdentifiableData

A fileattachable item is an item which can have a File attached to it.

This interface defines Hibernate database mapping for the file property to the database column file_id. If a subclass wants to map the property to another column, it should override the getFile() method and add a Hibernate tag in the comment.

Reference implementation

private FileData file;
public FileData getFile()
{
   return file;
}
public void setFile(FileData file)
{
   this.file = file;
}
