Class AbstractHierarchicalContentConvertedResourceView

java.lang.Object
  org.imemex.contentconverters.AbstractHierarchicalContentConvertedResourceView

All Implemented Interfaces:

java.lang.Comparable<ContentConvertedResourceView>, ContentConvertedResourceView, ResourceView

Direct Known Subclasses:

DefaultHierarchicalContentConvertedResourceView

public abstract class AbstractHierarchicalContentConvertedResourceView
extends java.lang.Object
implements ContentConvertedResourceView, java.lang.Comparable<ContentConvertedResourceView>

This class implements a resource view plugin id scheme in which the plugin id of a view is given by a concatenation of the plugin id from its parent view with a suffix. Note that this works on resource view graphs that are tree-shaped. To avoid unnecessary repetition of the prefix in all views that are indirectly to a given start view, we do not store the whole id on each view explicitly, but rather compute it when necessary based on the top-level views' plugin ids. Note that this scheme helps save main memory for the object representation of a resource view graph. The storage of plugin ids in the catalog may, however, remain using the innefficient alternative of storing all prefixes many times. NOTE: the ids assigned in this scheme are not updateable for now. That is done to avoid performance issues on computation that needs to unroll the id, such as hashCode.

This abstract implementation provides

• ResourceView.getName()
• ContentConvertedResourceView.getContentConvertedId()
• Comparable.compareTo()
• hashCode()
• equals()
• toString
