Method Detail

clearXid

public void clearXid()

Description copied from interface: MutableMessage

Clears the transaction ID field of this message (sets it to 0). This is provided for unit testing purposes, only.

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()

data

public OfmMutableEchoRequest data(byte[] data)

Sets the data; Since 1.0.

Parameters:

data - the data

Returns:

self, for chaining

Throws:

NullPointerException - if data is null

InvalidMutableException - if this instance is no longer writable

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

getData

public byte[] getData()

Returns a copy of the data.

Returns:

the data
