Detailed Description

A PendingInterest holds an interest which onInterest received but could not satisfy.

When we add a new data packet to the cache, we will also check if it satisfies a pending interest.

Constructor & Destructor Documentation

ndn::MemoryContentCache::PendingInterest::PendingInterest	(	const ptr_lib::shared_ptr< const Interest > &	interest,
		Face &	face
	)

Create a new PendingInterest and set the timeoutTime_ based on the current time and the interest lifetime.

Parameters

interest	A shared_ptr for the interest.
face	The face from the onInterest callback. If the interest is satisfied later by a new data packet, we will send the data packet to the face.

Member Function Documentation

const ptr_lib::shared_ptr<const Interest>& ndn::MemoryContentCache::PendingInterest::getInterest ( ) const

inline

Return the interest given to the constructor.

You must not modify this object - if you need to modify it then make a copy.

MillisecondsSince1970 ndn::MemoryContentCache::PendingInterest::getTimeoutPeriodStart ( ) const

inline

Return the time when this pending interest entry was created (the time when the unsatisfied interest arrived and was added to the pending interest table).

The interest timeout is based on this value.

Returns

The timeout period start time in milliseconds since 1/1/1970, as returned by ndn_getNowMilliseconds.

bool ndn::MemoryContentCache::PendingInterest::isTimedOut ( MillisecondsSince1970  nowMilliseconds ) const

inline

Check if this interest is timed out.

Parameters

nowMilliseconds

The current time in milliseconds from ndn_getNowMilliseconds.

Returns

true if this interest timed out, otherwise false.
