Constructor Detail

NxmHeader

public NxmHeader(org.opendaylight.yangtools.yang.common.Uint64 header)

Builds a NxmHeader from a BigInteger representation, that is, one for which BigInteger.longValue() produces a valid long representation.

Parameters:

header - the header as BigInteger.

See Also:

NxmHeader(long)

NxmHeader

public NxmHeader(long header)

Builds a NxmHeader from a long representation. For non experimenter, the 4 byte header are the least significant of the long, being the other 4 most significant bytes 0. For experimenter, the full 8 byte constitute the header, being the 4 least significant the experimenter id.

Parameters:

header - the header as a long.

NxmHeader

public NxmHeader(int oxmClass,
                 int nxmField,
                 boolean hasMask,
                 int length)

Build a non experimenter header from it's constituent fields.

Parameters:

oxmClass - the OXM class.

nxmField - the NXM field.

hasMask - the hasMask field.

length - the length field.

NxmHeader

public NxmHeader(int nxmField,
                 boolean hasMask,
                 int length,
                 long experimenterId)

Build a experimenter header from it's constituent fields. The OXM class will be set to 0xFFFF.

Parameters:

nxmField - the NXM field.

hasMask - the hasMask field.

length - the length field.

experimenterId - the esperimenter id field.
