Description copied from interface: MsgRepositoryIfc

Loads head of the payloads queue which holds items that would be expired after stated time with an option to delete them from repository after being retrieved. This is blocking method, which means if there is not data to return, implementation should block the call until data is available.

Specified by:

getMessageExpired in interface MsgRepositoryIfc

Parameters:

time - time in milliseconds representing time after which given message would be considered as expired

delete - boolean parameter controlling whether messages should be removed from repository after they retrieved.

Returns:

head of the payloads queue which holds items that would be expired after stated time with an option to delete them from repository after being retrieved.

getStanzaTo

public String getStanzaTo()
