nfd::cs::Entry::reset
void reset()
clears CS entry After reset, *this == Entry()
Definition: cs-entry.cpp:65
nfd::cs::Entry::isStale
bool isStale() const
checks if the stored Data is stale
Definition: cs-entry.cpp:59
nfd::cs::Entry::getName
const Name & getName() const
returns the name of the Data packet stored in the CS entry
Definition: cs-entry.hpp:108
nfd::cs::Entry::getData
const Data & getData() const
returns the Data packet stored in the CS entry
Definition: cs-entry.hpp:122
nfd::cs::Entry::getFullName
const Name & getFullName() const
returns the full name (including implicit digest) of the Data packet stored in the CS entry ...
Definition: cs-entry.hpp:115
nfd::cs::Entry::setData
void setData(const Data &data, bool isUnsolicited)
changes the content of CS entry and recomputes digest
Definition: cs-entry.cpp:44
nfd::cs::Entry
represents a base class for CS entry
Definition: cs-entry.hpp:42
nfd::cs::Entry::isUnsolicited
bool isUnsolicited() const
Data packet is unsolicited if this particular NDN node did not receive an Interest packet for it...
Definition: cs-entry.hpp:129
nfd::cs::Entry::getStaleTime
const time::steady_clock::TimePoint & getStaleTime() const
returns the absolute time when Data becomes expired
Definition: cs-entry.hpp:135
nfd::cs::Entry::updateStaleTime
void updateStaleTime()
refreshes the time when Data becomes expired according to the current absolute time.
