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
Transfers ownership to a new buffer, deallocating the current one.
buffer = IO::Buffer.new('test') other = buffer.transfer other # => # #<IO::Buffer 0x00007f136a15f7b0+4 SLICE> # 0x00000000 74 65 73 74 test buffer # => # #<IO::Buffer 0x0000000000000000+0 NULL> buffer.null? # => true
If the buffer is internal, meaning it references memory allocated by the buffer itself.
An internal buffer is not associated with any external memory (e.g. string) or file mapping.
Internal buffers are created using ::new and is the default when the requested size is less than the IO::Buffer::PAGE_SIZE and it was not requested to be mapped on creation.
Internal buffers can be resized, and such an operation will typically invalidate all slices, but not always.
Returns a human-readable string representation of this instruction sequence, including the label and path.
Set domain for which this cookie applies
A summary of cookie string.
Returns the index for the given header, if it exists; otherwise returns nil.
With the single argument header, returns the index of the first-found field with the given header:
source = "Name,Name,Name\nFoo,Bar,Baz\n" table = CSV.parse(source, headers: true) row = table[0] row.index('Name') # => 0 row.index('NAME') # => nil
With arguments header and offset, returns the index of the first-found field with given header, but ignoring the first offset fields:
row.index('Name', 1) # => 1 row.index('Name', 3) # => nil
Returns an ASCII-compatible String showing:
Class CSV::Row.
Header-value pairs.
Example:
source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n" table = CSV.parse(source, headers: true) row = table[0] row.inspect # => "#<CSV::Row \"Name\":\"foo\" \"Value\":\"0\">"
Returns a US-ASCII-encoded String showing table:
Class: CSV::Table.
Access mode: :row, :col, or :col_or_row.
Size: Row count, including the header row.
Example:
source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n" table = CSV.parse(source, headers: true) table.inspect # => "#<CSV::Table mode:col_or_row row_count:4>\nName,Value\nfoo,0\nbar,1\nbaz,2\n"
