If the access mode is :row or :col_or_row, and each argument is either an Integer or a Range, returns rows. Otherwise, returns columns data.
In either case, the returned values are in the order specified by the arguments. Arguments may be repeated.
Returns rows as an Array of CSV::Row objects.
No argument:
source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n" table = CSV.parse(source, headers: true) table.values_at # => []
One index:
values = table.values_at(0) values # => [#<CSV::Row "Name":"foo" "Value":"0">]
Two indexes:
values = table.values_at(2, 0) values # => [#<CSV::Row "Name":"baz" "Value":"2">, #<CSV::Row "Name":"foo" "Value":"0">]
One Range:
values = table.values_at(1..2) values # => [#<CSV::Row "Name":"bar" "Value":"1">, #<CSV::Row "Name":"baz" "Value":"2">]
Ranges and indexes:
values = table.values_at(0..1, 1..2, 0, 2) pp values
Output:
[#<CSV::Row "Name":"foo" "Value":"0">, #<CSV::Row "Name":"bar" "Value":"1">, #<CSV::Row "Name":"bar" "Value":"1">, #<CSV::Row "Name":"baz" "Value":"2">, #<CSV::Row "Name":"foo" "Value":"0">, #<CSV::Row "Name":"baz" "Value":"2">]
Returns columns data as row Arrays, each consisting of the specified columns data for that row:
values = table.values_at('Name') values # => [["foo"], ["bar"], ["baz"]] values = table.values_at('Value', 'Name') values # => [["0", "foo"], ["1", "bar"], ["2", "baz"]]
Creates a Regexp to match an address.
The main loop performed by a DRbServer’s internal thread.
Accepts a connection from a client, and starts up its own thread to handle it. This thread loops, receiving requests from the client, invoking them on a local object, and returning responses, until the client closes the connection or a local method call fails.
Maximum number of times to retry an idempotent request in case of Net::ReadTimeout, IOError, EOFError, Errno::ECONNRESET, Errno::ECONNABORTED, Errno::EPIPE, OpenSSL::SSL::SSLError, Timeout::Error. Should be a non-negative integer number. Zero means no retries. The default value is 1.
Adds an authenticator for Net::IMAP#authenticate. auth_type is the type of authentication this authenticator supports (for instance, “LOGIN”). The authenticator is an object which defines a process() method to handle authentication with the server. See Net::IMAP::LoginAuthenticator, Net::IMAP::CramMD5Authenticator, and Net::IMAP::DigestMD5Authenticator for examples.
If auth_type refers to an existing authenticator, it will be replaced by the new one.
Similar to search(), but returns unique identifiers.
Validates typecode v, returns true or false.
Private setter for the path of the URI::FTP.
