Method Detail

getPriority

public int getPriority()

Method which should return the priority level of this message. The messages can range in priority from 0 (highest priority) to Integer.MAX_VALUE (lowest) - when sending messages across the wire, the queue is sorted by message priority. If the queue reaches its limit, the lowest priority messages are discarded. Thus, applications which are very verbose should have LOW_PRIORITY or lower, and applications which are somewhat quiet are allowed to have MEDIUM_PRIORITY or possibly even HIGH_PRIORITY.

Returns:

This message's priority

getId

public RingId getId()

Method which returns this messages' id

Returns:

The id of this message

getRawMessage

public RawMessage getRawMessage()

Method which returns this messages' internal message

Returns:

The internal message of this message

getMessage

public Message getMessage()

getApplication

public java.lang.String getApplication()

Method which returns this messages' applicaiton name

Returns:

The application name of this message
