Method Detail

clearXid

public void clearXid()

Description copied from interface: MutableMessage

Clears the transaction ID field of this message (sets it to 0).

Specified by:

clearXid in interface MutableMessage

toImmutable

public OpenflowMessage toImmutable()

Description copied from interface: MutableMessage

Returns an immutable instance of this message. In essence, converts this message to be read-only.

It is expected that the reference to this mutable message will be dropped. Note that all method calls invoked on a MutableMessage after toImmutable() has been invoked will result in an InvalidMutableException being thrown.

Specified by:

toImmutable in interface MutableMessage

Returns:

an immutable instance of this message.

writable

public boolean writable()

Description copied from interface: MutableObject

Returns true if this mutable object is still writable. That is, the #toImmutable() method (defined on a sub-interface) has not yet been invoked.

Specified by:

writable in interface MutableObject

Returns:

true if this mutable object is still writable

toString

public String toString()

Overrides:

toString in class OfmPacketOut

bufferId

public OfmMutablePacketOut bufferId(BufferId bufferId)

Sets the buffer id; Since 1.0.

Parameters:

bufferId - the buffer id

Returns:

self, for chaining

Throws:

InvalidMutableException - if this instance is no longer writable

NullPointerException - if bufferId is null

inPort

public OfmMutablePacketOut inPort(BigPortNumber inPort)

Sets the ingress port that must be associated with the packet; Since 1.0. This must be either a valid standard switch port (from 1 to MAX) or CONTROLLER.

Note that in 1.0, port numbers are u16.

Parameters:

inPort - the ingress port

Returns:

self, for chaining

Throws:

InvalidMutableException - if this instance is no longer writable

NullPointerException - if inPort is null

IllegalArgumentException - if the port number is invalid

See Also:

Port

inPort

@Deprecated
public OfmMutablePacketOut inPort(OfmPacketIn pktIn)

Deprecated.

Sets the ingress port that must be associated with the packet; Since 1.0. This must be either a valid standard switch port (from 1 to MAX) or CONTROLLER.

Note that in 1.0, port numbers are u16.

Parameters:

pktIn - the ingress port

Returns:

self, for chaining

Throws:

InvalidMutableException - if this instance is no longer writable

NullPointerException - if inPort is null

IllegalArgumentException - if the port number is invalid

Port

addAction

public OfmMutablePacketOut addAction(Action act)

Adds an action to the action list; Since 1.0; Removed at 1.1.

Parameters:

act - the action to add

Returns:

self, for chaining

Throws:

InvalidMutableException - if this instance is no longer writable

VersionMismatchException - if action version does not match

NullPointerException - if act is null

data

public OfmMutablePacketOut data(byte[] data)

Sets the packet frame data; Since 1.0.

Parameters:

data - the frame data

Returns:

self, for chaining

Throws:

InvalidMutableException - if this instance is no longer writable

NullPointerException - if data is null

resetWritable

public void resetWritable()
