Method Detail

process

public HistoryFlow process(String flowKey,
                           String formKey,
                           String currentUrl)

Process/update the HistoryFlow stored in session for the flowKey, formKey, and currentUrl passed in.

If flowKey is blank or equal to "start", this will begin a new flow, otherwise the flow will continue by picking up the last flow that matches the flowKey, but if it also matches to a formKey that already is keyed to that flowKey, it will "jump" back to that HistoryFlow instead.

Parameters:

flowKey - the flow key

formKey - the form key

currentUrl - the currentUrl being process

Returns:

the HistoryFlow which represents the current HistoryFlow based on the parameters passed in

getMostRecentFlowByKey

public HistoryFlow getMostRecentFlowByKey(String key)

Get the flow that matches the flow key. This represents the most recent flow tied to this flow key.

Parameters:

key - the flow key

Returns:

the HistoryFlow, null if not found

getMostRecentFlowByFormKey

public HistoryFlow getMostRecentFlowByFormKey(String key,
                                              String formKey)

Get the flow by flowKey and formKey. This represents a flow specific to this combination.

Parameters:

key - the flow key

formKey - the form key

Returns:

the HistoryFlow if found, null otherwise
