prepare_data(job_dict, attr_name, default_value)

Method used to prepare specific SWF attributes, by converting entries from the original job dictionary

Parameters:

• job_dict – The job dictionary
• attr_name – The name of the attribute to be processed
• default_value – Default value to be used for the attribute, if not present in job_dict

Returns:

The processed value for attr_name, if present, or default_value otherwise

process_dictionary(job_dict)

Converts a job dictionary to a string to be written in the workload.

Parameters:job_dict – The job dictionary Returns:A properly formatted SWF string entry

class accasim.experimentation.schedule_writer.WorkloadWriter(path, overwrite=False, append=False)

Bases: abc.ABC

add_newline(job_dict)

Writes a new line corresponding to a job dictionary given as input

Parameters:job_dict – The input job dictionary

close_file()

Closes the output file stream

classmethod process_dictionary(job_dict)

This method must convert the job dictionary to a string formatted in a specific way, according to the implementation

Parameters:job_dict – Dictionary related to one specific job Returns:The string corresponding to the input dictionary
