LazyResource

class LazyResource(resourceProvider: LazyResourceProvider, cachedSize: Long, zipEntryName: String, href: String = zipEntryName) : Resource(source)

A Resource that loads its bytes only on-demand from an EPUB file.

zipEntryName is the resource's full path within the archive and is used as the lookup key. It is kept separate from href, which the package-document reader rewrites to be relative to the OPF.

The data is loaded on the first call that requires it, and can be released via close.
