Member Function Documentation

void ns3::PbbTlv::Deserialize ( Buffer::Iterator & start )

Deserializes a TLV from the specified buffer.

Parameters

start a reference to the point in a buffer to begin deserializing.

Users should not need to call this. TLVs will be deserialized by their containing blocks.
