Class ListStructure

java.lang.Object
oracle.javatools.data.Structure
oracle.javatools.data.ListStructure

All Implemented Interfaces:

java.lang.Iterable, java.util.Collection, java.util.List, Dirtyable

public class ListStructure

extends Structure

implements java.util.List

This class implements a list data structure that complements HashStructure. Instances of ListStructure can be contained in HashStructure and vice versa. ListStructure may also contain other instances of ListStructure.

Supported Types

The only types of objects that may be added to ListStructure are the same types that are supported by HashStructure:

• java.lang.String
• java.lang.Boolean
• java.lang.Integer
• java.lang.Long
• java.lang.Float
• java.lang.Double
• java.net.URL
• oracle.javatools.data.HashStructure
• oracle.javatools.data.ListStructure

The public methods of ListStructure are a subset of the methods declared by the List interface. This class may be enhanced in the future to implement the List interface completely.
