Field Detail

version

protected final ProtocolVersion version

Every structure knows what version it is representing.

Constructor Detail

OpenflowStructure

public OpenflowStructure(ProtocolVersion pv)

Constructs an OpenFlow structure.

Parameters:

pv - the protocol version

Method Detail

getVersion

public ProtocolVersion getVersion()

Description copied from interface: Structure

Returns the protocol version of this OpenFlow structure.

Specified by:

getVersion in interface Structure

Returns:

the structure protocol version

toString

public String toString()

Overrides:

toString in class Object

toDebugString

public String toDebugString()

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

Specified by:

toDebugString in interface Structure

Returns:

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

validate

public void validate()
              throws IncompleteStructureException

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.

Throws:

IncompleteStructureException - if the structure is not complete

hex

protected static String hex(long value)

Returns the given long as a string in hex form.

Parameters:

value - the value

Returns:

the value in hex form

hex

protected static String hex(int value)

Returns the given int as a string in hex form.

Parameters:

value - the value

Returns:

the value in hex form
