Interface ExtraduceSettings<S, A, EA>

Any supplementary data that should be available in processing.

Function that should be called to test whether current action is valid and should be passed for reducing. If the function returns false, the current action will be ignored (will not be passed into source reducer). This function is called after a function that is specified in prepareAction setting.

Size of list of fulfilled operations (processed actions). 0 (default value) means that data about operations should not be saved in the list. Negative value (for example -1) means that list size is not restricted.

Function that should be called at the end of each processing step.

Function that should be called at the start of each processing step.

Function that should be called after source (wrapped) reducer. State returned by source reducer and current action will be passed into the function.

Whether result of postreduce function should be used as new state in further processing. Default value is false.

Function that should be called to prepare current action for further processing before filtering. Value returned by the function will be used as new current action.

Function that should be called before source (wrapped) reducer.

Whether result of prereduce function should be used as new state in further processing. Default value is false.

Whether an array that is passed as action should be treated as list of actions that should be processed separately. Default value is true.

Supplementary arguments that should be passed into source (wrapped) reducer besides state and action. Or a function that returns such arguments.

Whether processing of an action that has a falsy value should be skipped. Default value is true. The corresponding check is made before calling a function that is specified in filterAction setting.

Function that should be called to transform current valid action after filtering. Value returned by the function will be used as new current action for further processing.
