Method Detail

intToIp

static java.lang.String intToIp(int i)

Converts an IP in a 32 bit integer to a dotted-decimal string

Parameters:

i - The IP address in a 32 bit integer

Returns:

An IP address string in dotted-decimal

arrToIp

static java.lang.String arrToIp(byte[] arr)

getNetworkDestinationMaskLen

static int getNetworkDestinationMaskLen(org.openflow.protocol.interfaces.OFMatch match)

Parse this match's wildcard fields and return the number of significant bits in the IP destination field. NOTE: this returns the number of bits that are fixed, i.e., like CIDR, not the number of bits that are free like OpenFlow encodes.

Returns:

a number between 0 (matches all IPs) and 63 ( 32>= implies exact match)

getNetworkSourceMaskLen

static int getNetworkSourceMaskLen(org.openflow.protocol.interfaces.OFMatch match)

Parse this match's wildcard fields and return the number of significant bits in the IP destination field. NOTE: this returns the number of bits that are fixed, i.e., like CIDR, not the number of bits that are free like OpenFlow encodes.

Returns:

a number between 0 (matches all IPs) and 32 (exact match)

getMaskLen

static int getMaskLen(byte[] mask)

serialize

public void serialize(org.openflow.protocol.interfaces.OFMatch match,
             org.codehaus.jackson.JsonGenerator jgen,
             org.codehaus.jackson.map.SerializerProvider provider)
               throws java.io.IOException,
                      org.codehaus.jackson.JsonProcessingException

Parameters:

match - OFMatch object

jgen - JsonGenerator object

provider - SerializerProvider object. not used.

Throws:

java.io.IOException

org.codehaus.jackson.JsonProcessingException
