Detailed Description

Sqlite3ProducerDb extends ProducerDb to implement storage of keys for the producer using SQLite3.

It contains one table that maps time slots (to the nearest hour) to the content key created for that time slot.

Note

This class is an experimental feature. The API may change.

The path of the SQLite file.

Member Function Documentation

virtual void ndn::Sqlite3ProducerDb::addContentKey ( MillisecondsSince1970  timeSlot, const Blob &  key  )

virtual

Add key as the content key for the hour covering timeSlot.

Parameters

timeSlot	The time slot as milliseconds since Jan 1, 1970 UTC.
key	The encoded key.

Exceptions

ProducerDb::Error

if a key for the same hour already exists in the database, or other database error.

Implements ndn::ProducerDb.

virtual void ndn::Sqlite3ProducerDb::deleteContentKey ( MillisecondsSince1970  timeSlot )

virtual

Delete the content key for the hour covering timeSlot.

If there is no key for the time slot, do nothing.

Parameters

timeSlot

The time slot as milliseconds since Jan 1, 1970 UTC.

Exceptions

ProducerDb::Error

for a database error.

Implements ndn::ProducerDb.

virtual Blob ndn::Sqlite3ProducerDb::getContentKey ( MillisecondsSince1970  timeSlot )

virtual

Get the content key for the hour covering timeSlot.

Parameters

timeSlot

The time slot as milliseconds since Jan 1, 1970 UTC.

Returns

A Blob with the encoded key.

Exceptions

ProducerDb::Error

if there is no key covering timeSlot or other database error.

Implements ndn::ProducerDb.

virtual bool ndn::Sqlite3ProducerDb::hasContentKey ( MillisecondsSince1970  timeSlot )

virtual

Check if a content key exists for the hour covering timeSlot.

Parameters

timeSlot

The time slot as milliseconds since Jan 1, 1970 UTC.

Returns

True if there is a content key for timeSlot.

Exceptions

ProducerDb::Error

for a database error.

Implements ndn::ProducerDb.
