Raised by Encoding and String methods when the source encoding is incompatible with the target encoding.
standard dynamic load exception
The base exception for JSON errors.
This exception is raised if a parser error occurs.
This exception is raised if the nesting of parsed data structures is too deep.
This exception is raised if a generator or unparser error occurs.
Generic error, common for all classes under OpenSSL module
General error for openssl library configuration files. Including formatting, parsing errors, etc.
The superclass for all exceptions raised by Ruby/zlib.
The following exceptions are defined as subclasses of Zlib::Error. These exceptions are raised when zlib library functions return with an error status.
Subclass of Zlib::Error when zlib returns a Z_DATA_ERROR.
Usually if a stream was prematurely freed.
Subclass of Zlib::Error
When zlib returns a Z_STREAM_ERROR, usually if the stream state was inconsistent.
Subclass of Zlib::Error
When zlib returns a Z_MEM_ERROR, usually if there was not enough memory.
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.
