Class IlvMContainer

java.lang.Object

ilog.views.sdm.metadata.IlvMResource

ilog.views.sdm.metadata.IlvMContainer

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

IlvMModel

public class IlvMContainer
extends IlvMResource

An implementation of metadata with RDF (Resource Description Framework). A Container is either a bag, a sequence, or an alternative. It simply holds resources.

The implementation leaves all the freedom to the list object which eventually holds the resources. Note also that there is no check on the validity of the resources (for example, no verification that ALT type is enabled and there is at least one child).

The implementation has been dramatically simplified in JViews 8.5 to improve performance. Only 'BAG' containers are supported, they contain statements only, and statements must define a non null subject. Subclass IlvMModel is backed by a map, and subclass IlvMList is backed by a list.

Since:

JViews 5.5

Constructor Detail

IlvMContainer

public IlvMContainer()

Creates an anonymous bag RDF container, with an empty ArrayList as list.
