🔍 Code Extractor

Initializes a TCP messenger client and sends a job to a server queue for processing graph-related tasks with specified label types and language settings.

Purpose

This function serves as an entry point for creating a print client connection to a server, configuring it with graph data, queue information, label types, and language settings, then triggering the job submission. It appears to be part of a distributed printing or document processing system where jobs are queued and processed remotely via TCP connections.

Source Code

def main(graph, server, queue, labeltype, language, obj_uid, **kwargs):
    tcp_messenger = print_client(graph, server, queue, labeltype, language, obj_uid, **kwargs)
    tcp_messenger.send_job()

Parameters

Parameter Details

graph: Graph data structure or identifier representing the data/document to be processed. Expected to be compatible with the print_client function's requirements.

server: Server address or hostname where the print client should connect. Typically a string containing IP address or domain name.

queue: Queue identifier or name where the job should be submitted. Used to route the job to the appropriate processing queue on the server.

labeltype: Type or format of labels to be used in the printing/processing operation. Specifies how labels should be rendered or formatted.

language: Language code or identifier for localization purposes. Determines the language used for labels, text rendering, or document generation.

obj_uid: Unique identifier for the object being processed. Used to track and identify the specific job or document in the system.

**kwargs: Additional keyword arguments passed through to the print_client function. Allows for extensibility and additional configuration options without modifying the function signature.

Return Value

This function does not explicitly return a value (implicitly returns None). The function's purpose is to perform side effects by creating a TCP messenger and sending a job, rather than returning data.

• asyncio
• socket

Usage Example

# Assuming print_client is defined elsewhere in the module
# Example usage:
graph_data = {'nodes': [1, 2, 3], 'edges': [(1, 2), (2, 3)]}
server_address = '192.168.1.100'
queue_name = 'print_queue_1'
label_type = 'barcode'
language_code = 'en-US'
object_uid = 'doc-12345'

# Call the main function
main(
    graph=graph_data,
    server=server_address,
    queue=queue_name,
    labeltype=label_type,
    language=language_code,
    obj_uid=object_uid,
    timeout=30,
    retry_count=3
)

Best Practices

• Ensure the print_client function is properly defined and handles connection errors gracefully
• Validate server address and queue name before calling this function to avoid connection failures
• Consider wrapping this function call in try-except blocks to handle potential network or connection errors
• The function assumes print_client returns an object with a send_job() method - ensure this contract is maintained
• Consider adding timeout parameters in kwargs to prevent indefinite blocking on network operations
• Ensure obj_uid is unique to prevent job conflicts or overwrites in the queue system
