parse_param_elem(input_source, enctypes, context)[source]

callback( level_prefix, parameter, parameter_value )

expand_incoming(trans, incoming, request_context)[source]
handle_input(trans, incoming, history=None, use_cached_job=False)[source]

Process incoming parameters for this tool from the dict incoming, update the tool state (or create if none existed), and either return to the form or execute the tool (only if ‘execute’ was clicked and there were no errors).

handle_single_execution(trans, rerun_remap_job_id, execution_slice, history, execution_cache=None, completed_job=None, collection_info=None)[source]

Return a pair with whether execution is successful as well as either resulting output data or an error message indicating the problem.

params_with_missing_index_file

Return all parameters that are dynamically generated select lists whose options refer to a missing .loc file.

get_static_param_values(trans)[source]
