Zlib::GzipReader
is the class for reading a gzipped file. GzipReader
should be used as an IO
, or -IO-like, object.
Zlib::GzipReader.open('hoge.gz') {|gz| print gz.read } File.open('hoge.gz') do |f| gz = Zlib::GzipReader.new(f) print gz.read gz.close end
Method
Catalogue The following methods in Zlib::GzipReader
are just like their counterparts in IO
, but they raise Zlib::Error
or Zlib::GzipFile::Error
exception if an error was found in the gzip file.
Be careful of the footer of the gzip file. A gzip file has the checksum of pre-compressed data in its footer. GzipReader
checks all uncompressed data against that checksum at the following cases, and if it fails, raises Zlib::GzipFile::NoFooter
, Zlib::GzipFile::CRCError
, or Zlib::GzipFile::LengthError
exception.
When an reading request is received beyond the end of file (the end of compressed data). That is, when Zlib::GzipReader#read
, Zlib::GzipReader#gets
, or some other methods for reading returns nil.
When Zlib::GzipFile#close
method is called after the object reaches the end of file.
When Zlib::GzipReader#unused
method is called after the object reaches the end of file.
The rest of the methods are adequately described in their own documentation.
The error thrown when the parser encounters illegal CSV
formatting.
Error raised by the DRb
module when an attempt is made to refer to the context’s current drb server but the context does not have one. See current_server.
Error raised by a dRuby protocol when it doesn’t support the scheme specified in a URI
. See DRb::DRbProtocol
.
Class
representing a drb server instance.
A DRbServer must be running in the local process before any incoming dRuby calls can be accepted, or any local objects can be passed as dRuby references to remote processes, even if those local objects are never actually called remotely. You do not need to start a DRbServer in the local process if you are only making outgoing dRuby calls passing marshalled parameters.
Unless multiple servers are being used, the local DRbServer is normally started by calling DRb.start_service
.
Raised when the provided IP address is an invalid address.
Raised when the address family is invalid such as an address with an unsupported family, an address with an inconsistent family, or an address who’s family cannot be determined.
Raised when the address is an invalid length.
ReadTimeout
, a subclass of Timeout::Error
, is raised if a chunk of the response cannot be read within the read_timeout.
Represents SMTP
error code 420 or 450, a temporary error.
Indicates a timeout resolving a name or address.
Represents a tagged XML
element. Elements
are characterized by having children, attributes, and names, and can themselves be children.
A class which provides filtering of children for Elements
, and XPath
search support. You are expected to only encounter this class as the element.elements
object. Therefore, you are not expected to instantiate this yourself.
A parent has children, and has methods for accessing them. The Parent
class is never encountered except as the superclass for some other object.
