explicit

Create a new name::Component from the buffer pointer (buffer pointer will be copied)

Parameters
bufferA pointer to an immutable buffer

This constructor will create a new tlv::NameComponent Block with buffer as a payload. Note that this method will not allocate new memory for and copy the payload until toWire() method is called.
