obspy.seedlink.easyseedlink¶

A simplified interface to the obspy.seedlink module.

The EasySeedLinkClient class contained in this module provides a more pythonic interface to the obspy.seedlink module with a focus on ease of use, while minimizing unnecessary exposure of the protocol specifics.

A client object can easily be created using the create_client() function, e.g. by providing a function to handle incoming data and a server URL:

from obspy.seedlink.easyseedlink import create_client

# A function to handle incoming data
def handle_data(trace):
    print('Received the following trace:')
    print(trace)
    print()

# Create the client and pass the function as a callback
client = create_client('geofon.gfz-potsdam.de', on_data=handle_data)
client.select_stream('BW', 'MANZ', 'EHZ')
client.loop()

For advanced applications, subclassing the EasySeedLinkClient class allows for more flexibility. See the EasySeedLinkClient documentation for an example.

Limitations

As of now, single station mode is not supported. Neither are in-stream INFO requests.

The client is using the SeedLinkConnection class and hence inherits all of its limitations. For example, erroneous packets are only logged, but otherwise ignored, with no possibility of handling them explicitly. Keepalive handling is completely encapsulated inside the connection object and cannot be easily influenced. Also, a HELLO is always sent to the server when connecting in order to determine the SeedLink protocol version.
