interface - Transfer | PLANTA Online-Hilfe

This topic discusses the functions to execute a transfer with the PLANTA link API and how to read the results.

Classes

The CounterDimmer class displays a dimmer during the transfer and records the results

All transfer methods return the CounterDimmer instance so you can check what happened

Property	Getter	Setter	Description
CounterDimmer.critical			`True` when a critical error aborted the transfer before it could finish
CounterDimmer.duration			Duration of the transfer in seconds
CounterDimmer.errors			Number of records that couldn't be received by the target module
CounterDimmer.received_records			Total number of records received by the target module
CounterDimmer.sent_records			Total number of records sent by the source module
CounterDimmer.was_successful			`True` when no errors were encountered

All transfer functions need an instance that is derived from ppms.interface.Config to execute the interface

If you do not have a reason to explicitly use the base ppms.interface.Config class you should use the ppms.interface.StaticConfig class as it outperforms the former heavily

Function	Parameters	Return Value	Description
direct_transfer`(invoker_module, config)`	invoker_module: A `Module` instance config: A `ppms.interface.Config` instance	`CounterDimmer`	Transfer the data from the source module to the target module. Use this if you have no pool module.
transfer_both_steps`(invoker_module, config)`	invoker_module: A `Module` instance config: A `ppms.interface.Config` instance	`CounterDimmer`	Perform `transfer_step_one()` and if it succeeded, call `transfer_step_two()`. If the source to pool step fails, the transfer is aborted and the `CounterDimmer` for that transfer is returned. If it succeeded the `CounterDimmer` for the second step is returned.
transfer_step_one`(invoker_module, config)`	invoker_module: A `Module` instance config: A `ppms.interface.Config` instance	`CounterDimmer`	Transfer the data from the source module to the pool module.
transfer_step_two`(invoker_module, config)`	invoker_module: A `Module` instance config: A `ppms.interface.Config` instance	`CounterDimmer`	Transfer the data from the pool module to the target module. Make sure to call `transfer_step_one()` before calling this!
