Class Queue

com.h3c.of.lib.OpenflowStructure

com.h3c.of.lib.msg.Queue

All Implemented Interfaces:

Structure

Direct Known Subclasses:

MutableQueue

public class Queue
extends OpenflowStructure

Represents a queue that can attach to a port.

An OpenFlow switch provides limited QoS support through a simple queuing mechanism. One (or more) queues can attach to a port and be used to map flow entries on it. Flow entries mapped to a specific queue will be treated according to that queue's configuration (e.g. min rate).

Instances of this class are immutable.

Method Detail

toString

public String toString()

Overrides:

toString in class OpenflowStructure

validate

public void validate()
              throws IncompleteStructureException

Description copied from class: OpenflowStructure

Validates this structure for completeness and throws an exception if the structure is considered "not complete".

This default implementation does nothing, i.e. default behavior is that structures are considered complete.

Subclasses should override this method to check that mandatory fields or other internal state is present, throwing an exception if it is not.

Overrides:

validate in class OpenflowStructure

Throws:

IncompleteStructureException - if the structure is not complete

getId

public QueueId getId()

Returns the ID of this queue.

Returns:

the queue ID

getPort

public BigPortNumber getPort()

Returns the ID of the port that this queue is attached to.

Protocol versions 1.0 and 1.1 will return null.

Returns:

returns the port

getProps

public List<QueueProperty> getProps()

Returns an unmodifiable view of the properties of this queue.

Returns:

the properties of this queue.
