ndn::name::Component::Component ( const ConstBufferPtr & buffer )

explicit

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

Parameters

buffer A 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.
