computed until another plugin asks for it.
<p>
By making metadata values lazy, no computation is done by the providing
plugin until absolutely necessary (if ever). Additionally,
LazyMetadataValue objects cache their values internally unless overridden
by a <a href="LazyMetadataValue.CacheStrategy.html" title="enum class in org.bukkit.metadata"><code>LazyMetadataValue.CacheStrategy</code></a> or invalidated at the individual or plugin
level. Once invalidated, the LazyMetadataValue will recompute its value
