Public Class methods

new(family)

Create the new socket for the provided family - ipv4, piv6, or unix.

  Socket.new(Socket::PF_INET)

@param [ Integer ] family The socket domain.

Public Instance methods

alive?()

Is the socket connection alive?

@example Is the socket alive? 

  socket.alive?

@return [ true, false ] If the socket is alive.

@deprecated Use connectable? on the connection instead.

close()

@example Close the socket. 

  socket.close

@return [ true ] Always true.

@since 2.0.0

connectable?()

For backwards compatibilty only, do not use.

@return [ true ] Always true.

@deprecated

eof?()

Tests if this socket has reached EOF. Primarily used for liveness checks.

@since 2.0.5

gets(*args)

Delegates gets to the underlying socket.

@example Get the next line. 

  socket.gets(10)

@param [ Array<Object> ] args The arguments to pass through.

@return [ Object ] The returned bytes.

@since 2.0.0

read(length)

Will read all data from the socket for the provided number of bytes. If no data is returned, an exception will be raised.

@example Read all the requested data from the socket. 

  socket.read(4096)

@param [ Integer ] length The number of bytes to read.

@raise [ Mongo::SocketError ] If not all data is returned.

@return [ Object ] The data from the socket.

@since 2.0.0

readbyte()

Read a single byte from the socket.

@example Read a single byte. 

  socket.readbyte

@return [ Object ] The read byte.
