Method Detail

toString

public String toString()

Overrides:

toString in class OpenflowMessage

toDebugString

public String toDebugString()

Description copied from class: OpenflowMessage

Returns a string representation useful for debugging. This default implementation delegates to OpenflowMessage.toString(), but subclasses are free to override this behavior.

Specified by:

toDebugString in interface Structure

Overrides:

toDebugString in class OpenflowMessage

Returns:

a (possibly multi-line) string representation of this message

validate

public void validate()
              throws IncompleteMessageException

Description copied from class: OpenflowMessage

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

This default implementation does nothing, i.e. default behavior is that messages 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 OpenflowMessage

Throws:

IncompleteMessageException - if the message is not complete

getBufferId

public BufferId getBufferId()

ID assigned by datapath (BufferId.NO_BUFFER if none); since 1.0.

Returns:

the buffer ID

getInPort

public BigPortNumber getInPort()

Returns the port on which the frame was received; Since 1.0.

Returns:

the ingress port

getInPhyPort

public BigPortNumber getInPhyPort()

Returns the physical port on which the frame was received; Since 1.1.

Returns:

the ingress physical port

getTotalLen

public int getTotalLen()

Returns the total length value from the in-port message header; Since 1.0.

Returns:

the total length value

getReason

public PacketInReason getReason()

Returns the reason the packet is being sent; Since 1.0.

Returns:

the reason

getTableId

public TableId getTableId()

Returns the ID of the table that was looked up; Since 1.1.

Returns:

the table ID

getCookie

public long getCookie()

Returns the cookie of the flow entry that caused the packet to be sent to the controller; Since 1.3.

Returns:

the cookie

getMatch

public Match getMatch()

Returns the packet metadata; Since 1.2. This match structure reflects the packet's headers and context when the event that triggers the PACKET_IN message occurred.

Returns:

the packet metadata

getData

public byte[] getData()

Returns a copy of the packet data; Since 1.0. Contains the packet itself, or a fraction of the packet if the packet is buffered.

Returns:

a copy of the packet data
