Method Detail

getParent

public IPacket getParent()

Description copied from interface: IPacket

Obtain the parent packet.

Specified by:

getParent in interface IPacket

Returns:

parent packet

setParent

public IPacket setParent(IPacket parent)

Description copied from interface: IPacket

Configure a new parent packet.

Specified by:

setParent in interface IPacket

Parameters:

parent - new parent

Returns:

getPayload

public IPacket getPayload()

Description copied from interface: IPacket

Obtain the packet payload.

Specified by:

getPayload in interface IPacket

Returns:

the payload

setPayload

public IPacket setPayload(IPacket payload)

Description copied from interface: IPacket

Assign the packet payload.

Specified by:

setPayload in interface IPacket

Parameters:

payload - new payload

Returns:

self

resetChecksum

public void resetChecksum()

Description copied from interface: IPacket

Reset any checksum as needed, and call resetChecksum on all parents.

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

clone

public Object clone()

This implementation of clone() is here to preserve backwards compatibility. Applications should not use clone() and instead use the duplicate() methods on the packet classes.
