# obspy.clients.seedlink.slclient.SLClient

class `SLClient`(loglevel='DEBUG', timeout=None)

  Bases: `builtins.object`

  Basic class to create and use a connection to a SeedLink server using a SeedLinkConnection object.

  A new SeedLink application can be created by sub-classing SLClient and overriding at least the packet_handler method of SLClient.

  Variables: | slconn SeedLinkConnection object for communicating with the SeedLinkConnection over a socket. verbose Verbosity level, 0 is lowest. ppackets Flag to indicate show detailed packet information. streamfile Name of file containing stream list for multi-station mode. selectors Selectors for uni-station or default selectors for multi-station. multiselect Selectors for multi-station. statefile Name of file for reading (if exists) and storing state. begin_time Beginning of time window for read start in past. end_time End of time window for reading windowed data. infolevel INFO LEVEL for info request only.
  Parameters: | timeout (float) Timeout in seconds, passed on to the underlying SeedLinkConnection.
