Methods

ParseFrom()

Parses the TLV from a given message at given offset, ensures the TLV is well-formed and its header and value are fully contained in the message. Can be used independent of whether the TLV is an Extended TLV or not.

ParseFrom()

FindIn()

Searches in a given message starting from message offset for a TLV of given type and if found, parses the TLV and validates that the entire TLV is present in the message. Can be used independent of whether the TLV is an Extended TLV or not.
