Subclass of Zlib::Error when zlib returns a Z_BUF_ERROR.
Usually if no progress is possible.
Subclass of Zlib::Error
When zlib returns a Z_VERSION_ERROR, usually if the zlib library version is incompatible with the version assumed by the caller.
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.
A CSV::Row is part Array and part Hash. It retains an order for the fields and allows duplicates just as an Array would, but also allows you to access fields by name just as you could if they were in a Hash.
All rows returned by CSV will be constructed from this class, if header row processing is activated.
The error thrown when the parser encounters illegal CSV formatting.
Superclass of all errors raised in the DRb module.
Error raised when an error occurs on the underlying communication protocol.
An exception wrapping a DRb::DRbUnknown object
An exception wrapping an error object
The default drb protocol which communicates over a TCP socket.
The DRb TCP protocol URI looks like: druby://<host>:<port>?<option>. The option is optional.
The protocol for DRb over an SSL socket
The URI for a DRb socket over SSL is: drbssl://<host>:<port>?<option>. The option is optional
Implements DRb over a UNIX socket
DRb UNIX socket URIs look like drbunix:<path>?<option>. The option is optional.
Error types.
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.
