public class TLfnThemeMetadata
extends ALfnResourceMetadata

A representation of a theme, which groups any number and type of resources. The representation provides the following parameters in addition to those provided by the superclass:

• resource IDs: the IDs of the resources grouped by a theme (optional, defaults to the empty collection if unspecified, never null
• keywords: the keywords associated with a theme (optional, defaults to the empty collection if unspecified, never null

Instances of this class are immutable, thus thread-safe.

A theme refers to other resources and as such a theme represents a collection of resources. There is no hierarchical relationship (such as ownership) between the theme and its referenced resources. The theme's resources can contain nested themes and forms a directed graph of resources. Note that the graph of resources formed by a theme may contain:

• loops (recusion) caused by nested themes
• duplicate resources
• unresolved resources

For easy traversal of a theme, the TLfnThemeMetadataTraverser can be used.
