Logs a message
at the info (syslog info) log level, or logs the message returned from the block.
Returns true if the stream is finished.
Finishes the stream and flushes output buffer. If a block is given each chunk is yielded to the block until the input buffer has been flushed to the output buffer.
Decompresses string
. Raises a Zlib::NeedDict
exception if a preset dictionary is needed for decompression.
This method is almost equivalent to the following code:
def inflate(string) zstream = Zlib::Inflate.new buf = zstream.inflate(string) zstream.finish zstream.close buf end
See also Zlib.deflate
Inputs deflate_string
into the inflate stream and returns the output from the stream. Calling this method, both the input and the output buffer of the stream are flushed. If string is nil
, this method finishes the stream, just like Zlib::ZStream#finish
.
If a block is given consecutive inflated chunks from the deflate_string
are yielded to the block and nil
is returned.
Raises a Zlib::NeedDict
exception if a preset dictionary is needed to decompress. Set
the dictionary by Zlib::Inflate#set_dictionary
and then call this method again with an empty string to flush the stream:
inflater = Zlib::Inflate.new begin out = inflater.inflate compressed rescue Zlib::NeedDict # ensure the dictionary matches the stream's required dictionary raise unless inflater.adler == Zlib.adler32(dictionary) inflater.set_dictionary dictionary inflater.inflate '' end # ... inflater.close

Closes the GzipFile
object. Unlike Zlib::GzipFile#close
, this method never calls the close method of the associated IO
object. Returns the associated IO
object.
Same as IO
.
The line number of the last row read from this file.
Specify line number of the last row read from this file.
Resets the position of the file pointer to the point created the GzipReader
object. The associated IO
object needs to respond to the seek
method.

Returns the number of hard links to stat.
File.stat("testfile").nlink #=> 1 File.link("testfile", "testfile.bak") #=> 0 File.stat("testfile").nlink #=> 2
Produce a nicely formatted description of stat.
File.stat("/etc/passwd").inspect #=> "#<File::Stat dev=0xe000005, ino=1078078, mode=0100644, # nlink=1, uid=0, gid=0, rdev=0x0, size=1374, blksize=4096, # blocks=8, atime=Wed Dec 10 10:16:12 CST 2003, # mtime=Fri Sep 12 15:41:41 CDT 2003, # ctime=Mon Oct 27 11:20:27 CST 2003, # birthtime=Mon Aug 04 08:13:49 CDT 2003>"
Returns true
if stat is writable by the effective user id of this process.
File.stat("testfile").writable? #=> true
Returns true
if stat is a symbolic link, false
if it isn’t or if the operating system doesn’t support this feature. As File::stat
automatically follows symbolic links, symlink?
will always be false
for an object returned by File::stat
.
File.symlink("testfile", "alink") #=> 0 File.stat("alink").symlink? #=> false File.lstat("alink").symlink? #=> true
Returns true
if stat has its sticky bit set, false
if it doesn’t or if the operating system doesn’t support this feature.
File.stat("testfile").sticky? #=> false
Returns true
if key
is registered
Returns the number of referenced objects
Returns a human-readable string representation of this instruction sequence, including the label
and path
.
