class

Compress::Zlib::Reader

Inherits IO::Buffered / IO / Reference / Object

A read-only IO object to decompress data in the zlib format.

Instances of this class wrap another IO object. When you read from this instance instance, it reads data from the underlying IO, decompresses it, and returns it to the caller.
