Class OFErrorCauseData

java.lang.Object

org.projectfloodlight.openflow.types.OFErrorCauseData

All Implemented Interfaces:

Writeable, PrimitiveSinkable

public class OFErrorCauseData
extends Object
implements Writeable, PrimitiveSinkable

A special-purpose wrapper for the 'data' field in an OFErrorMsg message that contains a byte serialization of the offending message. This attempts to parse the offending message on demand, and if successful will present the parsed message.

Field Detail

NONE

public static final OFErrorCauseData NONE

A default 'empty' cause. Note: the OFVersion OF_13 passed in here is irrelevant, because parsing of the 0-byte array will always return null, irrespective of the version.

Method Detail

of

public static OFErrorCauseData of(byte[] data,
                                  OFVersion version)

getData

public byte[] getData()

getParsedMessage

public com.google.common.base.Optional<OFMessage> getParsedMessage()

read

public static OFErrorCauseData read(io.netty.buffer.ByteBuf bb,
                                    int length,
                                    OFVersion version)

putTo

public void putTo(com.google.common.hash.PrimitiveSink sink)

Description copied from interface: PrimitiveSinkable

Dump the state of this object into a PrimitiveSink (e.g., a Hasher) for the purpose of computing a strong hash. Equality contract: Equal objects must dump the equal data into the sink, non-equal objects must dump different data into the sink. Please see the interface documentation of PrimitiveSink for more details and caveats/traps.

Specified by:

putTo in interface PrimitiveSinkable

Parameters:

sink - the sink to dump the object state into.

writeTo

public void writeTo(io.netty.buffer.ByteBuf bb)

Specified by:

writeTo in interface Writeable

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
