visitMessagesWithDeadlineBeforeTimestamp

public boolean visitMessagesWithDeadlineBeforeTimestamp(long timestamp,
 MessageState.Index startAt,
 MessageState.ExpiredMessageVisitor visitor)

Description copied from interface: MessageState

Visits the messages with expired deadline, using the provided visitor. The visitor stops when all messages with expired deadline have been visited, but can also be controlled through the visitor function.

Specified by:

visitMessagesWithDeadlineBeforeTimestamp in interface MessageState

Parameters:

timestamp - Timestamp used to determine whether the deadline has expired

startAt - Index used to start the iteration at; visiting starts at the beginning when startAt is null

visitor - This method is called for each message with expired deadline. It must return a boolean that when true allows the visiting to continue, or when false stops the visiting.

Returns:

true when the visiting is stopped due to the returned value of the last call to visitor, otherwise false

exist

public boolean exist(org.agrona.DirectBuffer name,
 org.agrona.DirectBuffer correlationKey,
 org.agrona.DirectBuffer messageId)

Specified by:

exist in interface MessageState
