zlib.ZipEntry.rawContent

The entry's raw (still compressed, if applicable) content when it is held in memory, or null when there is no in-memory buffer to expose - for an entry created with zlib.ZipEntry.createStream(), or a file-backed entry returned by zipFile.get(), whose bytes are read from disk on demand rather than retained. Use zipEntry.content() or zipEntry.contentIterator() to read a file-backed entry.
